NEUR 3002 Final - Practice MC
questions with correct answers
Which statistical test is appropriate when you are comparing more than 2 sets of interval/ratio-scale
scores generated by variation of a single predictor variable through the independent groups design, and
when your data meets the assumptions of parametric tests?
A) One way ANOVA
B) Factorial ANOVA
C) Student's independent groups t test
D) Pearson's chi squared test - correct answer A) One way ANOVA
Which statistical test is appropriate when you are comparing 2 sets of interval/ratio scale scores
generated through a repeated measures design, when your data deviates very dramatically from the
assumptions of parametric tests?
A) Wilcoxon sum rank/Mann Whitney U
B) Friedman's ANOVA
C) Pearson's Chi squared test
D) Wilcoxon signed-rank test - correct answer D) Wilcoxon signed-rank test
To convert the Freidman's ANOVA test statistic to a p value, which distribution do we use?
A) Normal
B) F
C) t
D) Chi-squared - correct answer D) Chi-squared
, Which of the following tests is closest to being a non parametric version of the paired test?
A) Wilcoxon signed rank
B) Friedman's ANOVA
C) Wilcoxon sum rank/Mann Whitney U
D) Kurskal-Wallis test - correct answer A) Wilcoxon signed rank
The Wilcoxon rank sum test involves calculating the sum of ranks. Briefly describe how these sum of
ranks totals are obtained (no need to go into detail on procedures in excel - just give me the conceptual
steps). (2 marks) - correct answer Each score is converted to a rank for both groups and then the sum of
these ranks for each group separately calculated.
Chi-squared tests are most obviously used for datasets where:
A) The predictor variable is categorical
B) The outcome variable is categorical
C) There is no predictor variable, outcome variable can be any measurement scale.
D) There is no outcome variable, predictor variable can be any measurement scale. - correct answer B)
The outcome variable is categorical
Your research data, to be analyzed using the chi-squared test, takes the form of a 3x4 contingency table.
How many degrees of freedom would the test have?
A)12
B) Cannot answer without knowing the sample size.
C) 1
D) 6 - correct answer D) 6
A research study on infertility explores association between the following two categorical variables:
Variable 1: Treatment with a new experimental drug vs. placebo
