By using software we have to find the first, second, and third quartile for the given data set.We have to draw a box-and whisker plot that represent the data.

Step 2 of 3:

(a)

The median is the middle most value of the data set after arranging the data in an order (Q2).First quartile is the median of data points which is below the median (Q1).Third quartile is the median of data points which is above the median (Q3).

We can find the quartiles by using Minitab. Enter the given data in Minitab Go to Stat Select Basic Statistic Choose Display descriptive statistics Select the data set Select the statistics we want Then press ok. So, the first quartile of the data set, Q1=2.
