Here you will learn about the mode, the measure of central tendency concerned with the value(s) of greatest frequency in a data set.Noela is working on a homework assignment for her social studies class, and needs to find the 10-year historical period between 1900 and 2000 with the greatest number of recorded hurricanes worldwide.

Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.




Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.


Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.
