b) It is used in situations which require the collection of numerical data
c) It is often used to explore research areas we know little or nothing about
d) All of the above are true

2. Social psychologists often use stars as notation for statistical probability (the ‘p value’), which of the following is correct:
a) * denotes p < .05
b) ** denotes p < .05
c) *** denotes p < .001
d) All of the above

3. An ANOVA examining the effects of participants’ sex, as well as their favourite season (winter, spring, summer or autumn) on a personality test score (the EPQ), would be a:
a) 2 (Sex) by 2 (Season) Unrelated ANOVA
b) 1 (Sex) by 1 (Season) Unrelated ANOVA
c) 2 (Sex) by 4 (Season) Unrelated ANOVA
d) None of the above

4. A parametric test is based on the assumption that you have:

b) Collected ordinal data
c) Collected categorical data
d) A representative sample

5. A Simple Linear Regression analysis has which of the following features:
a) It is based on the formula for a line
b) It is useful for making predictions about human behaviour
c) It utilises a single Predictor value
d) All of the above are true

6. Which of the following should NOT be true of your data in order for a parametric test to be run:
a) The DV must be scale data
b) The data must be skewed
c) The data must be normally distributed
d) The data must have homogeneity of variance
Although you've got the answer they are looking for here, its not actually true that the data needs to be normally distributed. Its actually the sampling distribution has to be normally distributed.

7. Statistical probability is:
a) The probability that the effects occurred due to error/chance
b) The probability that the null hypothesis is true
c) Indicates significance when it is close to 0
d) All of the above
This question also does not make sense...

I am stuck between b and d for question 10. Any help would be much appreciated.

Thanks!

Question 10 is probably B. Did you get this MCQ from class? the questions are rubbish :P

Question 2 looks wrong because B isn't right.

I'd guess question 4 was wrong because you can use parametric tests when you have a binary outcome variable, but i'm not sure.

Q10 is b
