**What is a numerical summary stats?**

A numerical summary is a number used to describe a specific characteristic about a data set.

**Are box plots used for numerical data?**

Box plots are used to show distributions of numeric data values, especially when you want to compare them between multiple groups. They are built to provide high-level information at a glance, offering general information about a group of data’s symmetry, skew, variance, and outliers.

### How do you find a number summary?

How to Find a Five-Number Summary: Steps

- Step 1: Put your numbers in ascending order (from smallest to largest).
- Step 2: Find the minimum and maximum for your data set.
- Step 3: Find the median.
- Step 4: Place parentheses around the numbers above and below the median.
- Step 5: Find Q1 and Q3.

**What is the 5 number summary on Boxplot?**

A box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value. We use these values to compare how close other data values are to them.

**How do you analyze a Boxplot?**

- Step 1: Assess the key characteristics. Examine the center and spread of the distribution.
- Step 2: Look for indicators of nonnormal or unusual data. Skewed data indicate that data may be nonnormal.
- Step 3: Assess and compare groups. If your boxplot has groups, assess and compare the center and spread of groups.

#### How do you read a box plot?

How to Read a Box Plot. A boxplot is a way to show a five number summary in a chart. The main part of the chart (the “box”) shows where the middle portion of the data is: the interquartile range.

## What do box plots represent?

In descriptive statistics, a box plot or boxplot (also known as box and whisker plot) is a type of chart often used in explanatory data analysis. Box plots visually show the distribution of numerical data and skewness through displaying the data quartiles (or percentiles) and averages.
