You will use this data for the Box and Whisker chart. You will get the third table as shown below.

In the second row – compute values as First Quartile - Minimum Value.Retain the first row – Minimum Value as it is.Step 2 − Create a third table from the second table, computing the differences − The resulting second table will be as given below.

PARTS OF A BOX AND WHISKER PLOT SERIES

Step 1 − Compute the following for each of the series – 2014, 20 using Excel Functions MIN, QUARTILE and MAX. Suppose you are given the following data −Ĭreate a second table from the above table as follows − The outliers also help in identifying the reasons for the data to get outcast. Traffic patterns on a particular route to streamline the signals that are enroute. Laboratory results to draw conclusions on a new drug that is invented. Question-Answer patterns for a competitive examination to finalize the combination of categories. Survey responses on a particular product or service to understand the user’s preferences.Įxamination results to identify which students need more attention in a particular subject. And the data can be diverse that is drawn from any field for statistical analysis. You can use Box and Whisker chart wherever to understand the distribution of data.

Whiskers indicate variability outside the upper and lower quartiles, and any point outside the whiskers is considered as an outlier.Ī Box and Whisker chart looks as shown below. The minimums and maximums outside the first and third quartiles are depicted with lines, which are called whiskers. In a Box and Whisker chart, numerical data is divided into quartiles and a box is drawn between the first and third quartiles, with an additional line drawn along the second quartile to mark the median. For example, you can use a Box and Whisker chart to compare experimental results or competitive exam results. Box and Whisker charts, also referred to as Box Plots are commonly used in statistical analysis.
