Question 1

Most research studies require the use of complex statistics such as regression.

Accepted Answer

False

Question 2

Boxplots can be especially helpful for displaying the distribution of responses when the responses are skewed.

Accepted Answer

Boxplots are useful for visualizing the distribution of data, including skewness, as they display the median, quartiles, and potential outliers, providing a clear summary of the data's spread and asymmetry.

Question 3

The creation of fake data, such as creating a fictitious row of data in a spreadsheet for people who never completed a questionnaire or never participated in an experiment is referred to as which of the following?

A) Fabrication
B) Falsification
C) Plagiarism
D) Justification

A

Accepted Answer

Fabrication refers to the act of creating false data or results, such as inventing data that was never collected or experiments that were never conducted.

Question 4

For what type of variables is it not possible to create a histogram or boxplot?&#10;A) Ratio variables&#10;B) Interval variables&#10;C) Ordinal variables&#10;D) Categorical variables

Accepted Answer

Histograms and boxplots are used for numerical data, not categorical data, which lacks a natural order or numerical value.

Question 5

What type of variables typically result from counting something so there are gaps between acceptable values?&#10;A) Nominal variables&#10;B) Binomial variables&#10;C) Continuous variables&#10;D) Discrete variables

Accepted Answer

Discrete variables result from counting and have distinct gaps between values, as they can only take specific, separate values.
