## What is the width of a box plot?

The “width” of a box in a box plot chart has no significance to the data. It is simply an adjustment of the chart size to the number of items displayed. The critical parameters of a box plot are the LENGTH of the box and the length of the “whiskers” extending up and down from the box.

## What does the width of the box in a box plot indicate?

The widths of the box plot indicate the size of the samples. The wider the box, the larger the sample.

**What is the line on a Boxplot?**

In a typical box plot, the top of the rectangle indicates the third quartile, a horizontal line near the middle of the rectangle indicates the median, and the bottom of the rectangle indicates the first quartile.

**What is the horizontal line within the box of a Boxplot?**

In a box plot: The box represents the middle 50% or so of the numeric values. A horizontal line within the rectangle represents the median of all values (specifically, the value that is exactly in the middle of all values).

### How do you interpret a boxplot in statistics?

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 does a normal box plot look like?

If the distribution is normal, there are few exceptionally large or small values. The mean will be about the same as the median, and the box plot will look symmetric. If the distribution is skewed to the left, most values are ‘large’, but there are a few exceptionally small ones.

What is a Boxplot?

- The minimum (the smallest number in the data set).
- First quartile, Q1, is the far left of the box (or the far right of the left whisker).
- The median is shown as a line in the center of the box.
- Third quartile, Q3, shown at the far right of the box (at the far left of the right whisker).

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

Box Plot interquartile range: How to find it

- Step 1: Find Q1. Q1 is represented by the left hand edge of the “box” (at the point where the whisker stops).
- Step 2: Find Q3.
- Step 3: Subtract the number you found in step 1 from the number you found in step 3.

## Which is the horizontal line of boxes?

The horizontal line in the box plot indicates the mean and the box indicates the upper and lower quartiles, with the vertical lines representing the minimum and maximum values.
