6. Using the data set, construct a histogram of the sales data. Is

the data set unimodal or multimodal? Is the dataset left skewed, right skewed, or

symmetric?

The first column is the data in “YYYYMM” format (202001

would be January 2020) and the second column contains the total sales for

a single US retail location for that time period.

Answer #1

the data set multimodal since it has three high peak that is three modes.

The histogram is symmetric in nature which indicates our data is symmetrically distributed

It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others).
