9. WHY STATISTICS IN RESEARCH?
1. Statistical methods involved in carrying out a study
include planning, designing, collecting data, analysing,
drawing meaningful interpretation and reporting of the
research findings.
Statistics
Planning
Designing
Collecting Data
Analyzing
Drawing Meaningful Interpretation
Reporting
10. WHY STATISTICS IN RESEARCH?
1. The statistical analysis gives meaning to the meaningless
numbers, thereby breathing life into a lifeless data.
2. The results and inferences are precise only if proper
statistical tests are used.
11. FEW MORE QUESTIONS ????? (VARIABLE)
Which statistical technique will you use? Why?
1. To find out the influence of one variable on other variable
2. To find out the association between variables
3. To find our the relationship between two variables?
4. To find out the level of study variable
â
12. FEW MORE QUESTIONS ????? (SAMPLE)
Which statistical technique will you use? Why?
1. If the sample size is less than 10
2. For random sample
3. Non random sample
4. Homogeneous sample and heterogeneous sample
â
13. FEW MORE QUESTIONS ????? (SCALES)
Which statistical technique will you use? Why?
1. For ratio scale data
2. For interval scale data
3. For ordinal scale data
4. For nominal scale data
â
22. When to Use?
Parametric
1. When the distribution is normal
2. Large Sample
3. Interval and Ratio distributions
4. Random sampling
5. When decided to make an
assumptions
Nonparametric
1. when the distribution is not
normal
2. Small Sample
3. Nominal and ordinal
distribution
4. Non Random sampling
5. When it is not make an
assumptions

45. LEARNING OUTCOME
At the end of the session the learners will be able to understand and
apply in their field
1. Types of statistical Analysis
âDescriptive Data Analysis
âInferential Statistical Analysis
âDifference Statistical Analysis
âAssociation Statistical Analysis
âPredictive Statistical Analysis
2. When to use parametric and non parametric?
47. TYPES OF STATISTICAL ANALYSIS
Types
of
Statistical
Analysis
Descriptive What are the characteristics of the respondents?
Inferential What are the characteristics of the population?
Differences Are two are more groups same or different?
Association Are two or more variables related in a systematic way?
Predictive
Can we predict one variable if we know one or more other
variables in the study?
66. Example of samples from two populations with the same mean but different dispersion.
The blue population is much more dispersed than the red population.
87. When to Use Parametric or Non parametric
Statistics?
88.
89.
90. WHEN TO USE?
Parametric
1. Decided to make assumption about
the Population
2. Probabilistic distribution is normal
3. Sampling is based on probability or
randomness
4. Data collected on the scale of
interval or ratio
5. Large Sample size
6. Homogeneous data
7. Independent data set
Non Parametric
1. Donât make assumption but describe
2. Distribution is arbitrary or not normal
3. Sampling is non probability or non
randomness
4. Data collected on the scale of
nominal or interval
5. Small Sample size
6. Homogeneous and Heterogeneous
data
7. Any data set
