Deck 28: How Do I Decide What to Do With My Data

Question 1

What is the first step in designing a research project after developing the research question?

A) To decide how to break down a main effect
B) To decide what types of statistical test you need to run to analyse your data
C) To decide how to break down an interaction
D) To decide which research approach you will take

Answer 1

D

Question 2

What is the difference between a t test and ANOVA?

A) The t test determines whether two conditions are statistically different from each other, whereas ANOVA determines whether three or more conditions are statistically different from each other.
B) The t test determines whether three or more conditions are statistically different from each other, whereas ANOVA determines whether two conditions are statistically different from each other.
C) There is no difference.
D) The t test shows the strength of association between two sets of variables, whereas ANOVA shows the strength of the association between three or more sets of variables.

Answer 2

A

Question 3

Which of the following tests do you need to use when you compare the means between two conditions from one set of participants, on the same continuous, dependent variable?

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

Answer 3

A

Question 4

When do you use a factorial mixed ANOVA?

A) When you have independent measures variables
B) When you have a mixture of independent measures and repeated measures variables
C) When you have repeated measures variables
D) When you have three or more independent measures measures variables

Question 5

Which of the following options is incorrect about breaking down a main effect while using ANOVA?

A) If your main effect is not significant, then there is no need for any further contrasts.
B) If you have a two-tailed hypothesis, then you will need to use post hoc contrasts when there is a significant main effect.
C) If you have a one-tailed hypothesis, then you will need to use post hoc contrasts when there is a significant main effect.
D) If your main effect is significant, but there are only two conditions, there is no need for any further contrasts.

Question 6

Which of the following tests do you need to use when the outcome variable is categorical, and the predictor variables are categorical and/or continuous in a correlation research study?

A) Linear regression
B) Hierarchical regression
C) Multiple regression
D) Logistic regression

Question 7

What is the purpose of factor analysis?

A) The purpose of factor analysis is to reduce many individual items into a smaller number of variables.
B) The purpose of factor analysis is to use a set of variables to predict an outcome variable.
C) The purpose of factor analysis is to look for a relationship between two variables.
D) The purpose of factor analysis is to determine if there is a significant difference between the means of two groups.

Question 8

What do you need to do if your data are not normally distributed?

A) Use post hoc tests.
B) Use parametric tests.
C) Use non-parametric tests or data transformation techniques.
D) Use Bonferroni correction.

Question 9

Which of the following ways is not used to evaluate the assumption of similar variability across a dataset?

A) Levene's test
B) Tukey test
C) Mauchly's test
D) Scatterplot of residuals

Question 10

Which of the following methods do you need to use it when you want to explore in detail how participants are making sense of their personal lived experience?

A) Content Analysis
B) Discourse Analysis
C) Grounded Theory
D) Interpretative Phenomenological Analysis
