|
research issues: EXTRANEOUS VARIABLES |
-"nuscaince" variables -don't vary systematically with the IV -researcher may control some of these |
what are these? (3 points) |
|
|
research issues- CONFOUNDING VARIABLES |
-change systematically with the IV - therefore can't be sure if observed change in the DV is due to the CV or IV |
what are these? key point |
|
|
research issues: DEMAND CHARACTERISTICS |
-Pps in experiments being aware they are, and acting in a way they believe is desirable to produce the hypothesised results |
what are they? |
|
|
research issues- INVESTIGATOR EFFECTS |
-effect of investigators behaviour on the outcome of research (researcher bias) |
what is it? |
|
|
research techniques: RANDOMISATION |
use of chance when designing experiments to control bias effects. |
|
|
|
research techniques: STANDARDISATION |
using the same formalised procedures for all pps in the study. |
|
|
|
research techniques: CONTROL GROUPS |
used for setting a comparison (act as a baseline). |
|
|
|
research techniques: SINGLE AND DOUBLE BLIND |
SB- pps don't know the aim of the study DB- pps and researcher don't know aims of the study BOTH REDUCE BIAS |
|
|
|
INDEPENDENT GROUPS (+ EVAL) |
- 1 group do condition A, 1 do condition B (random allocation) + no order effects +pps won't guess aim -pps variables -more pps |
Definition, 2 pos 2 neg |
|
|
REPEATED MEASURES (+ EVAL) |
-same pps take part in all experiment conditions +more control over pps variables +fewer pps -order effects -pps may guess aims |
definition, 2 pos 2 neg |
|
|
MATCHED PAIRS (+ EVAL) |
- 2 groups of pps are used but they're also paired on pps variables e.g. Age +pps variables, high validity +no order effects -matching isn't perfect -more pps |
Definition, 2 pos 2 neg |
