AICE PSYCHOLOGY REVIEW TIPS QUESTIONS AND
ANSWERS SET A+
✔✔Correlation - ✔✔Relationship between two measured variables
✔✔Positive Correlation - ✔✔If one variable increases so does the other variable
✔✔Negative Correlation - ✔✔As one variable increases the other decreases
✔✔No Correlation - ✔✔The two variables do NOT appear to be related
✔✔AIM - ✔✔Written before study stating the study's purpose
✔✔Hypothesis - ✔✔Predicts the finding of the study
✔✔Directional (One-tailed) hypothesis - ✔✔Predicts the significant difference and
direction of results (EX. Females will be able to spell more words correctly out of 25
compared to males)
✔✔Non-Directional (Two-tailed) hypothesis - ✔✔
✔✔Null Hypothesis - ✔✔A testable statement saying that any difference or correlation in
the results is due to chance. no pattern in the the results is because of the variables
being studied.
✔✔Repeated Measures - ✔✔When the participant takes parts in all levels of the IV
Strength
- Controlled
- Fewer participants needed
Weakness
, - Chance for demand characteristics
- Participants get better practice
- Fatigue and boredom
✔✔Independent Measures - ✔✔When the participant takes part in only one level of the
IV
Strength
- Less likely to guess AIM (demand characteristics)
Weakness
- More people are required personally could affect DV since it is just one person
✔✔Extraneous Variable - ✔✔Variables that can influence the relationship between the
IV & DV
- They can effect the outcome or add error to the experiment
- EX. Listening to music
✔✔Uncontrolled Variables - ✔✔- Variables that cannot be controlled by the researcher
- Can lower the validity of an experiment (affects the DV)
✔✔Participant Variables - ✔✔Variables that the participant brings to the study that can
affect the DV ( Prejudice, previous experience with similar study, personality)
✔✔Situational Variables - ✔✔Variables that the situation brings to the study that can
affect the DV
EX. Noise, weather, temperature
✔✔Quantitative Data - ✔✔Numerical form to get statistical analysis
Strength
- Easy to compare data and get good conclusions
Weakness
- Miss out on valuable information. If analysis is simply yes or now we don't know the
WHY?
✔✔Qualitative Data - ✔✔Data comes in the from of a description
Strength
- Rich and detailed responses. You get to see the WHY response
Weakness
