Deck 17: Which Statistical Test Should I Use

Question 1

You have run a study where you compared intelligence scores across three separate groups of participants: cat owners, dog owners and tortoise owners. Which type of research design have you used?

A) Categorical (or frequency)
B) Experimental
C) Qualitative
D) Correlational

Answer 1

B
Explanation: It is experimental because you are comparing scores across different condition, and those scores exist on a continuum.

Question 2

You have conducted focus groups with psychology students to find out more about their views towards feedback on assignments. Which type of research design have you used?

A) Categorical (or frequency)
B) Experimental
C) Qualitative
D) Correlational

Answer 2

C
Explanation: It is qualitative because you will have collected qualitative data through the focus groups.

Question 3

You want to run a categorical (or frequency) design study. One of the categorical variables is whether the participant has siblings or not. The other categorical variable is their level of extraversion, either high or low. How would you describe the correct way of analysing these data?

A) 2x2 chi square goodness of fit
B) 4 x 1 chi square test of association
C) 4 x 1 chi square goodness of fit.
D) 2x2 chi square test of association

Answer 3

D
Explanation: It is a test of association because there are two categorical variables (siblings and extraversion), and it is 2 x2 because each variable has two categories: siblings or not, high or low extraversion.

Question 4

If you are designing an experimental study and trying to develop your dependent variable (DV). Which of the following is true?

A) The DV can only have two categories
B) The DV must have three of more categories
C) The DV must be non-parametric
D) The DV must be a continuous score

Question 5

You conduct a study comparing sense of humour, measured from 0 - 100, between comedians and accountants. How would you analyse the data collected in this study?

A) Repeated measures t test
B) Chi square test of association
C) Independent measures t test
D) One-way independent measures ANOVA

Question 6

You conduct a study comparing sense of humour, measured from 0 - 100, between comedians and accountants. What is the independent variable (IV) in this design?

A) The participant's occupation
B) Being an accountant
C) Being a comedian
D) The participant's sense of humour

Question 7

You conduct a study comparing sense of humour, measured from 0 - 100, between comedians and accountants. What is the dependent variable (DV) in this design?

A) The participant's occupation
B) Being an accountant
C) Being a comedian
D) The participant's sense of humour

Question 8

You run a study to look at whether people with more years of formal education read more books per year. What type of research design did you use?

A) Categorical (or frequency)
B) Experimental
C) Correlational
D) Qualitative

Question 9

You run a study to look at whether people with more years of formal education read more books per year. If you were to analyse the data collected in this study using a parametric analysis you would use a __________, whereas if you were to use a non-parametric analysis you would use a __________.

A) Pearson's correlation, Spearman's correlation
B) Spearman's correlation, Pearson's correlation
C) Linear regression, Pearson's correlation
D) Pearson's correlation, linear regression

Question 10

You run a study to look at whether people with more years of formal education read more books per year. If you wanted to use years of education to predict the number of books read, which method of analysis would you use?

A) Chi square
B) Linear regression
C) Pearson's correlation
D) Spearman's correlation
