## What is a box graph?

Description. Box Plot (or Box Chart) is a convenient way of graphically depicting groups of numerical data through their quartiles. It provides a visual representation of statistical data based on the minimum, first quartile, median, third quartile, and maximum. Outliers can be plotted on Box Plots as individual points …

**What is a box chart called?**

Description. A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles. The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles.

### How do you plot a box graph?

- Step 1: Calculate the quartile values. First you need to calculate the minimum, maximum and median values, as well as the first and third quartiles, from the data set.
- Step 2: Calculate quartile differences.
- Step 3: Create a stacked column chart.
- Step 4: Convert the stacked column chart to the box plot style.

**What is Boxplot used for?**

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.

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

The far left of the chart (at the end of the left “whisker”) is the minimum (the smallest number in the set) and the far right is the maximum (the largest number in the set). Finally, the median is represented by a vertical bar in the center of the box. Box plots aren’t used that much in real life.

**What is the difference between box plot and histogram?**

Histograms are a special kind of bar graph that shows a bar for a range of data values instead of a single value. A box plot is a data display that draws a box over a number line to show the interquartile range of the data. The ‘whiskers’ of a box plot show the least and greatest values in the data set.

## How do you find the range in a box plot?

To find the range of all plots, subtract the smallest value from the largest value.

**How do you explain boxplot results?**

The median (middle quartile) marks the mid-point of the data and is shown by the line that divides the box into two parts. Half the scores are greater than or equal to this value and half are less. The middle “box” represents the middle 50% of scores for the group.

### What can we conclude from Boxplot?

Using box plots we can better understand our data by understanding its distribution, outliers, mean, median and variance. Box plot packs all of this information about our data in a single concise diagram. It allows us to understand the nature of our data at a single glance.
