## How do you find the whiskers on a box plot?

The whiskers are the two lines outside the box, that go from the minimum to the lower quartile (the start of the box) and then from the upper quartile (the end of the box) to the maximum. The graph is usually presented with an axis that indicates the values (not shown on figure 4.5.

## Does a box plot have whiskers?

A box-plot usually includes two parts, a box and a set of whiskers as shown in Figure 2. The box is drawn from Q1 to Q3 with a horizontal line drawn in the middle to denote the median. The whiskers can be defined in various ways.

**What do long whiskers on a box plot represent?**

A plot with long whiskers represents a greater range for the overall sample than simply a longer box itself does. Data covering a greater range is naturally less reliable as an indicator of highly probable values, but given the option, longer whiskers are less of a concern than a long box.

### What is a whisker diagram?

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum.

### What box and whisker plots show?

A boxplot, also called a box and whisker plot, is a way to show the spread and centers of a data set. Measures of spread include the interquartile range and the mean of the data set. Measures of center include the mean or average and median (the middle of a data set).

**What do the whiskers on a box plot represent?**

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.

## What is the first step to create this box and whisker plot?

The first step in constructing a box-and-whisker plot is to first find the median (Q2), the lower quartile (Q1) and the upper quartile (Q3) of a given set of data. You are now ready to find the interquartile range (IQR). The interquartile range is the difference between the upper quartile and the lower quartile.

## How to make a box and whisker plot?

1) Create a box and whisker chart: 2) Select your data—either a single data series, or multiple data series. (The data shown in the following illustration is a portion of the data used to create the sample chart shown above). 3) On the ribbon, click the Insert tab, and then click (the Statistical chart icon), and select Box and Whisker.

**How to make box and whisker plots?**

– The bottom and top of each box are the 25th and 75th percentiles of the sample, respectively. – The red line in the middle of each box is the sample median. – The whiskers are lines extending above and below each box. – Observations beyond the whisker length are marked as outliers. – Notches display the variability of the median between samples.
