Example Exam Questions
Series I
Disclaimer: Below you find example questions that are representative for the exam in
terms of the kind of questions and the level at which we test. Notice that the questions may
not cover all topics in every detail.
Also notice that tables (Z-table and t-table) and formulas (see below) will be provided with
the exam.
Formulas for Statistics:
𝑋−𝜇
Standardized values (Z-values): 𝑍 = 𝜎
𝑆𝑋
Standard error of the mean: 𝑠𝑋̅ =
√𝑁
𝑋̅−𝜇𝐻0
t statistic: 𝑡 = 𝑆𝑋

Questions:
1. Suppose the variable income is operationalized as follows: the 10% lowest incomes
receive a score 1, the next 10% higher incomes a score 2, and so forth. Hence, income is
scored from 1 through 10. What is the measurement level for income?
a. Nominal
b. Ordinal
c. Scale
2. On a random day, researchers measured how much time students spend on traveling to
the university (in minutes). They want to present the distribution of the traveling time in a
graph. What kind of graph should they best use from the following list?
a. Histogram
b. Bar Chart
c. Scatterplot
3. Consider the following three scatter plots for two different data sets. For which data set
will Pearson’s correlation coefficient be most likely the highest?
Date Set A Date Set B
a. Date Set A
b. Date Set B
