1. Participants must be given the right to
withdraw at any time,
Participants must be fully informed after the
study – of what it was about and where
their findings fit.
Participants must agree to take part and
having their data used, knowing as mush
as possible about the study (they consent,
and it is informed consent).
The researcher must be competent to carry
out the study..
There must be no deceit – participants
must be fully informed.

2. - Describe &
Evaluate the Experimental Research
following research Methods
methods:
Lab
Field
Natural
-Describe &
evaluate each
Mr Oakes

3. Write your idea on a post it note and stick on
the board.

4. The research deliberately manipulates the
independent variable (change) while
maintaining strict control over any other
variable.

5. Weaknesses
Strengths  Unnatural situation –
 Rigorous control over likely to lack validity
situation & ppts – can (lack ecological
repeat -tested for validity & mudane
reliability realism)
 Controls extraneous  Data lacks depth,
variables – few detail – reductionist
confounding variables method – by looking
at the parts the whole
 Objective & Scientific might not be studied –
(use stats) lacks validity

6. The researcher deliberately manipulates the
independent variable but does this in the
subjects environment

7. Strengths Weaknesses
 Careful controls –  Control over
replicable -tested for extraneous variables
reliability is harder than lab
exp – possibly more
 In natural setting - confounding
more ecologically valid variables – lack
than lab exp validity
 Less bias from  Ethical issues
sampling – subjects
don’t have to brought
to the lab

8. Cut and sort the statements (there will be one
left over)

9. The independent variable is changed by
natural occurrence, the researcher just
records the effect on the dependent variable

10. Strengths Weaknesses
 IV naturally occuring
 Lack of control
- Mudane realism &
Ecological Validity
 No cause and effect
as IV not being
 Research can be directly
carried out when manipulated
manipulating the IV
would usually be  Difficult to repeat –
unethical or not
cant test reliability
practical & generalise
