Question

A population has a mean of 377 and a mode of 333. If 17 points are added to each, which is a true choice?

a.The mean will increase by 17, and the mode will stay the same.

b.The mean and the mode will both stay the same.

c.Both the mean and mode will increase by 17.

d.The mean will stay the same, and the mode will increase by 17.

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
