PRESENTATIONS
FOR
CREATING
CHANGING

WORLD
RULES
5
…five simple rules for creating world-changing presentations.
11
TREAT
YOUR
AS
AUDIENCE
KING
The first rule is: Treat your audience as king.

Your audience deserves to be treated like royalty. Design a
presentation that meets their needs, not just yours.
13

YOU
CAN
DO

WHY

THE
STEPS

ACTION
THEY
NEED
TO
TO
TAKE

Audiences want to know what you can do for them, why they
should adopt your view, and the steps they need to follow to
take action.
14
$
Give them those things in a clear, easily understandable way…
15

…and you will undoubtedly find favor with the king.
16
SPREAD
IDEAS
AND
MOVE
PEOPLE
2
The second rule is: Spread ideas and move people.
17
BLAH

Your audience didn’t show up to read your 60 page on screen
dissertation.

They’re there to see you. To be inspired by your message…
19

…and witness the quality of your thought.

20
AN
OTHER
ME
ET
ING
You are not giving your presentation to have another meeting.
You are there to covey meaning.
21
So, consider including imagery that powerfully illustrates your
point.
22

Sometimes moving images can inspire in a way that static slides
cannot. A slow moving animation creates a sense of nostalgia.
23
WHICH
PRODUCT

HAS
IT
ALL?
A sequential build adds a sense of suspense.
24
And a thought-provoking video moves your audience in a way
that can change not only minds, but hearts.
25
HELP
SEE

WHAT
YOU
SAYING
THEM
ARE
3
The next rule is: Help them see what you are saying.
26

Half of the people in your audience are verbal thinkers and the
other half are visual.
27

Combining minimal text with meaningful visuals means that
you’ll reach everyone.
28
Brainstorm graphics that will effectively communicate your
message…
29

THE
PROCESS
…and replace those words with a picture, chart or diagram.
Then apply a consistent treatment to your graphics to give your
whole presentation a unified look so that your audience is
attracted to, rather than distracted from, your message.
30
PRACTICE
DESIGN
NOT

DECORATION
4
Rule number 4: Practice design, not decoration.
31

As tempting as it is to fill your slides with stuff, often de-
decorating is the best policy.
32
Any writer or designer will tell you that 90% of the creative
process…

*The text to the left of the “:” is not required (it is for

*Course Number and Name: CIS105 Introduction to Information

*Date of Submission: (Use the current date)
Abstract
Level 1 headers should be centered and boldface.
Do not indent first sentence in the Abstract.
The Abstract is often optional for research papers. Students
enrolled in courses at Strayer University should verify with the
instructor if an Abstract is required for the paper. CIS105 does
not have a major APA paper as an assignment. The Abstract
should be written in block form, which means that the paragraph
should not be indented. The Abstract should contain between
150 and 250 words and should not contain in-text citations or
references. The Abstract provides a brief summary of the paper
and usually contains words such as, “This paper will discuss…”,
or “The purpose of this paper is to…”. The Abstract should not
to be confused with the thesis statement. Write the Abstract in

short and concise sentences that tell the story of the paper. The
Abstract should be written after the entire paper has been
completed. The Abstract should be located after the title page,
but before the introduction of the paper. Do not write the
Abstract in first-person; write the Abstract in third-person.
Introduction and Thesis Statement
The title of the paper is centered but not bolded for this
instance.
Do indent the first sentence in a paragraph.
How to Format an APA Paper According to 6th Edition
Standards. Input and center the above title of the paper at the
top of the page. This title is not bolded but the titles in the rest
of the body will be centered and bolded. An introduction and
thesis statement header is not used and should not be included.
The first sentence of the introduction should grab the attention
of the audience of readers. It should be an original, broad
statement, quote, or paraphrase. Narrow down the broad topic to
a specific argument that is worthy of research and writing.
Research papers should be written in a narrative format. Write
the paper in third-person; refrain from writing papers in first-
and second-person. Provide background, definitions, or other
details about the topic that will help the audience of readers
understand the topic more effectively and writer’s logical flow
of the paper. The introduction paragraph should lead into a
specific or main topic, known as the thesis statement. The thesis

statement should be the last sentence of the introduction
paragraph. The type of thesis statement used in this paper is the
expository thesis statement. In this case, the expository thesis
statement is one comprehensive sentence that displays three
main argumentative points that the writer thinks are critically
important for the readers to know. The writer needs to conduct
research about these specific opinions and support them with
objective and accurate data. Here is an example of an expository
thesis statement: In order to write a great research paper,
writers must understand word processing software, APA 6th
Edition formatting, and how to structure content. Without a
thesis statement, there can be no body of the paper or
conclusion.
Body of the Paper
Note: The body contains three (3) sections with Level 1
Headings: Word Processing Software, APA 6th Edition
Formatting, and Structuring Content. These should be Centered
and Bolded.
Note: A block quote is highlighted in yellow to show you in the
text to the right. Do not include the yellow highlight in your
document. Be sure to format this item according to APA 6th
edition standards.
Remember to indent the first sentence of a paragraph.
Word Processing Software

The body of the paper should outline the three main
argumentative points in the thesis statement. Therefore, if a
Header such as “Word Processing Software” is used, the
paragraph or subsequent paragraphs within the section should
discuss thesis statement argument #1.
Data that presents opposing viewpoints related to different
Word processing software, the types that exist, advantages and
disadvantages, and any other relevant information should be
written within the paragraph or subsequent paragraphs.
Subsequent paragraphs may be necessary. This can be up to the
writer, the instructor, or the constraints of the assignment. For
example, a five-paragraph paper should include:
1. An introduction paragraph, with thesis statement at the end of
the introduction paragraph.
2. A body of the paper that contains three paragraphs related to
the thesis statement.
3. A conclusion paragraph that includes a restatement of the
thesis statement, whether it is confirmed or disconfirmed, a
summary of the findings of each paragraph, and final words
based on the writer’s perspective of the research paper.
However, a research paper that is required to be longer in length
(i.e., 5-6 pages, 8-10 pages) will more than likely require
additional paragraphs and sections. This is when the use of
Headers and sub-Headings may prove useful. The writer will
need to ensure that the logical flow of data naturally transitions

from paragraph to paragraph. Content also needs to be written
objectively, not with bias. Reducing bias in language can be
easier achieved with third-person writing and critical thinking.
Writers should support the argument with credible research
from peer-reviewed resources. Wikipedia, the media, or other
non-peer-reviewed articles may not always be reliable or
acceptable. Validity and accuracy can sway the opinions of
readers if data is derived from reputable sources. Remember,
one major goal of the paper is to convince the audience of the
writer’s opinion makes sense.
Another major goal of the paper is to increase the knowledge of
the writer. If this research is done well, it should add to the
body of knowledge. The last sentence of this paragraph should
transition nicely into thesis statement argument #2.
APA 6th Edition Formatting
This paragraph or series of paragraphs within this section
should present data about argument #2, APA 6th Edition
Formatting. Just as paragraph #1 within the body of the paper,
data that presents opposing viewpoints related to APA 6th
Edition formatting should be researched and written.
Approximately 80-85% of the paper should be written in the
writer’s original words; 15-20% of the paper should be written
with in-text citations. Paraphrasing in-text citations is preferred
compared to quoting author statements. However, if quotations

are used, the writer must write them correctly. For example,
thirty-nine (39) words or less require in-text citations to be
written as follows: “The quoted sentence” (Author Last Name,
Year of Publication, page or paragraph number). Here are a few
examples:
1. “The quoted sentence” (Phillips, 2013, p. 3).
2. Phillips (2013) stated, “The quoted sentence” (para. 7).
The two previous sentences utilized the author of this paper’s
name for illustration purposes only. Quoting forty (40) words or
more requires a different formatting called Blocked Quotes.
This is how they must be written:
A tutorial will show you how to create this within the paper.
Please pay close attention to how it is written. Select the
appropriate words to lead into the hanging indentation or
blocked quote. Please note that the formatting is similar, but the
period should be written immediately after the sentence and not
before the in-text citation. (Author Last Name, 2013, p. 3)
A sentence that naturally transitions into thesis statement #3
should be written here.
Structuring Content
This paragraph should discuss thesis statement argument #3,
which is how to structure content within a research paper. The
same guidelines apply for this topic and paragraph. The writer
should articulate the components necessary to write this entire

paper from beginning to end so that the content will make sense
to anyone, anywhere in the world, who decides to read it.
Writers should not write with colloquialisms or verbiage that
people in different venues, environments, or cultures will not
understand. Writers should also consider writing in past tense as
well. The content in this paragraph or section should transition
nicely to the conclusion section of the paper.
Conclusion
The header should be Centered and Bolded.
The first sentence should re-state the thesis statement in
different or similar words and remember to continue indenting
the first sentence in a paragraph. This sentence will remind the
reader of the overall arguments researched within the paper
based on the writer’s opinions on the topic.
The writer should then summarize the main points of each
paragraph or section. Writers should refrain from inputting
quotes and paraphrases in the conclusion paragraph or
paragraphs. Writers should continue to write in third-person.
The last few sentences are where the writer inputs his/her
objective perspective of the overall research. In other words, the
writer should have learned something from conducting this
research and should state those facts clearly and concisely. The
final product should equate to a great research paper that
contains objectively written content that is well-formatted in
APA 6th Edition by learning how to use the functions within

word processing software.
The reference page should be written on the next page, in
alphabetical order, and according to a specific format.
Instructions for writing Headers are written within Appendix A.
Instructions for writing in-text citations are written within
Appendix B.
References
The header should be Centered and Bolded.
Use a new page for References.
Note: Cite the provided references using the APA 6th edition
standards for formatting a Web page.

RULES

…five simple rules for creating world-changing presentations.
11
TREAT
YOUR
AS
AUDIENCE
KING

The first rule is: Treat your audience as king.
12

Your audience deserves to be treated like royalty. Design a
presentation that meets their needs, not just yours.

Audiences want to know what you can do for them, why they
should adopt your view, and the steps they need to follow to
take action.

Give them those things in a clear, easily understandable way…
15

…and you will undoubtedly find favor with the king.
16
SPREAD
IDEAS
AND

PEOPLE

The second rule is: Spread ideas and move people.

Your audience didn’t show up to read your 60 page on screen

18

They’re there to see you. To be inspired by your message…

…and witness the quality of your thought.

You are not giving your presentation to have another meeting.
You are there to covey meaning.
21

So, consider including imagery that powerfully illustrates your
point.
22
Sometimes moving images can inspire in a way that static slides
cannot. A slow moving animation creates a sense of nostalgia.
23

WHICH
PRODUCT
HAS
IT
ALL?
A sequential build adds a sense of suspense.
24
And a thought-provoking video moves your audience in a way
that can change not only minds, but hearts.

25
HELP

WHAT
YOU

The next rule is: Help them see what you are saying.
26

Combining minimal text with meaningful visuals means that
you’ll reach everyone.
28
Brainstorm graphics that will effectively communicate your
message…

…and replace those words with a picture, chart or diagram.
Then apply a consistent treatment to your graphics to give your
whole presentation a unified look so that your audience is
attracted to, rather than distracted from, your message.

Final Exam
Spring 2017

The final exam will be posted at 12:01 am on March 3, and it is
due at 11:59 pm on March 5, 2017. Eastern Time is our
reference
time.
This is an open-book exam. You may refer to your text and
other course materials
as you work on the exam, and you may use a calculator. You
must complete the
exam individually. Neither collaboration nor consultation with
others is allowed.
It is a violation of the UMUC Academic Dishonesty and
Plagiarism policy to use
unauthorized materials or work from others.
Answer all 20 questions. Make sure your answers are as

complete as possible.
Show all of your supporting work and reasoning. Answers that
come straight
from calculators, programs or software packages without any
explanation will not
be accepted. If you need to use technology (for example, Excel,
online or hand-
held calculators, statistical packages) to aid in your calculation,
you must cite the
sources and explain how you get the results.
Record your answers and work on the separate answer sheet
provided.
You must include the Honor Pledge on the title page of your
submitted final exam.

Exams submitted without the Honor Pledge will not be
accepted.
1. True or False. Justify for full credit.
(a) If A and B are any two events, then P(A AND B) = P(A) +
P(B).
(b) If the variance of a data set is 0, then all the observations in
this data set must be identical.
(c) A normal distribution curve is always symmetric to its mean.
(d) When plotted on the same graph, a distribution with a mean
of 60 and a standard deviation

of 5 will look more spread out than a distribution with a mean
of 40 and standard deviation
of 8.
(e) In a left-tailed test, the value of the test statistic is -2. The
test statistic follows a
distribution with the distribution curve shown below. If we
know the shaded area is 0.03,
then we have sufficient evidence to reject the null hypothesis at
0.05 level of significance.
2. Choose the best answer. Justify for full credit.
(a) A study was conducted at a local college to analyze the
average GPA of students graduated
from UMUC in 2016. 100 students graduated from UMUC in
2016 were randomly selected,

and the average GPA for the group is 3.5. The value 3.5 is a
(i) statistic
(ii) parameter
(iii) cannot be determined
(b) The hotel ratings are usually on a scale from 0 star to 5
stars. The level of this measurement is
(i) interval
(ii) nominal
(iii) ordinal
(iv) ratio
(c) On the day of the last presidential election, UMUC News
Club organized an exit poll in which
specific polling stations were randomly selected and all voters

were surveyed as they left those
polling stations. This type of sampling is called:
(i) cluster
(ii) convenience
(iii) systematic
(iv) stratified
3. The frequency distribution below shows the distribution for
IQ scores for a random sample of
1000 adults. (Show all work. Just the answer, without
supporting work, will receive no credit.)

IQ Scores Frequency
Cumulative Relative
Frequency
50 - 69 23
70 - 89 249
90 -109 0.722
110 - 129
130 - 149 25
Total 1000

(a) Complete the frequency table with frequency and cumulative
relative frequency. Express the
cumulative relative frequency to three decimal places.
(b) What percentage of the adults in this sample has an IQ score
of at least 110?
(c) Which of the following IQ score groups does the median of
this distribution belong to?
70 – 89, 90 – 109, or 110 – 129? Why?
4. The five-number summary below shows the grade distribution
of a STAT 200 quiz for a
sample of 100 students.
Answer each question based on the given information, and

explain your answer in each case.
(a) What is the range in the grade distribution?
(b) Which of the following score bands has the most students?
(i) 30 - 50
(ii) 50 - 70
(iii) 70 - 90
(Iv) Cannot be determined
(c) How many students in the sample are in the score band
between 70 and 100?

5. Consider selecting one card at a time from a 52-card deck.
What is the probability that the first
card is an ace and the second card is also an ace? (Note: There
are 4 aces in a deck of cards)
(Show all work. Just the answer, without supporting work, will
receive no credit.)
(a) Assuming the card selection is with replacement.
(b) Assuming the card selection is without replacement.
6. There are 2000 students in a high school. Among the 2000
students, 1500 students have a
laptop, and 900 students have a tablet. 500 students have a
laptop and a tablet. Let L be the
event that a randomly selected student has a laptop, and T be
the event that a randomly selected

student has a tablet. (Show all work. Just the answer, without
supporting work, will receive no
credit.)
(a) Provide a written description of the complement event of (L
OR T).
(b) What is the probability of complement event of (L OR T)?
7. Consider rolling a fair 6-faced die twice. Let A be the event
that the sum of the two rolls is at
most 6, and B be the event that the first one is an even number.
(a) What is the probability that the sum of the two rolls is at
most 6 given that the first one is an
even number? Show all work. Just the answer, without
supporting work, will receive no credit.

(b) Are event A and event B independent? Explain.
8. Answer the following two questions. (Show all work. Just
the answer, without supporting
work, will receive no credit).
