Research methods
- Variables
- The independent variable is
the variable that a researcher
manipulates which has a
direct effect on the DV.
- The dependent variable is
the variable that is affected
by changes in the DV.
- (IV) affects (DV)
- The independent variable is
the variable that a researcher
manipulates which has a
direct effect on the DV.
- Hypothesis
- Directional (one tailed) is knowing
the direction of results. tells you
what effect the IV has on the DV.
- Non-directional (two tailed) is if
the hypothesis just suggests that
there is going to be a difference
due to the IV but doesn't tell you
how its directed.
- Null hypothesis: there will be no significant
difference between (condition 1) and
(condition 2) in terms of the (DV). Any
difference will be due to chance.
- Directional (one tailed) is knowing
the direction of results. tells you
what effect the IV has on the DV.
- sampling
- Random
- Volunteer
- Opurtunity.
- Random
- Experimental design
- Independent groups . Splitting the
sample into two groups using allocation.
Each group completes different
conditions and the results are then
compared.
- Repeated measures.
Everyone in the sample
completes both conditions.
Results are then compared.
- Matched pairs. Participants are
paired based on their qualities.
They are then split into two
groups away from each other.
- Independent groups . Splitting the
sample into two groups using allocation.
Each group completes different
conditions and the results are then
compared.
- Extraneous variables are any
other variables apart from the IV
that are likely to affect the DV.
- if they become important
enough they can become
confounding variables. You
can't confidently
prove/disprove the hypothesis.
- if they become important
enough they can become
confounding variables. You
can't confidently
prove/disprove the hypothesis.
- Demand
characteristics are
features of the
experimental situation
that act as clues.
- investigator effects is when
the investigator may
accidently influence behavior.
- Double-blind techniques are where
neither the researcher or the participant
know the condition the participant is in.
- Double-blind techniques are where
neither the researcher or the participant
know the condition the participant is in.
- Single-blind
techniques are where
the participant is not
told what condition
they are in so can't
work out the demands
of the researcher.
- investigator effects is when
the investigator may
accidently influence behavior.
- Types of experiment
- Lab
- Field
- Natural. Natural
changes in the IV.
Not manipulated.
- Lab
- A Pilot study is a
smaller scale version
of the experiment.
Helps the researcher
see whether their
research has internal
validity.
