What is the most appropriate measure of central tendency to report for the following survey item:

"What is your highest level of education?"

1) GED 2) Associate's 3) Bachelor's 4) Master's 5) PhD

• Mean

• Median

• Mode

• Variability

Measures of central tendency tell us what is most _________ about a variable

• useful

• typical

• unusual

• accurate

When dealing with a skewed distribution, the most appropriate measure of central tendency to report would be:

• mean

• median

• mode

• trimmed mean

The most appropriate measure of central tendency to use with a dichotomous variable is:

• mean

• median

• mode

• standard deviation

For nominal level data (e.g. undergraduate major), the best way to represent variability is

• frequency distribution or graph

• range

• standard deviation

• mode

When reporting mean as the measure of central tendency, it is best practice to also report _______ as your measure of variability

• mean deviation

• standard deviation

• range

• variance

This measure of variability is the distance that encompasses all attributes within a data set

• standard deviation

• range

• interquartile range

• variance

When determining your grades in class, which measure of central tendency would I use?

• mean

• trimmed mean

• arithmetic mean

• weighted mean
