32, 34, 39, 40, 40, 42, 45, 50, 52, 68, 12, 13, 18, 20, 22, 24, 26, 26, 28, 32 create a box and whisker plot for the data.
Step 1:
Write the given data in ascending order.
12,13,18,20,22,24,26,26,28,32,32,34,39,40,40,42,45,50,52,68
Number of data-20
Step 2:
Find the median of the ascending order data
Median, Q2= 32 (average of two middle values 32, and 32)
Step 3:
Divide the data into two equal halves of first 10 set of data and last 10 set of data. Find their median.
First halve:
12,13,18,20,22,24,26,26,28,32
Median, Q1= 23 (22 and 24)
Second halve:
32,34,39,40,40,42,45,50,52,68
Median Q3= 41 (40 and 42)
Step 4:
Draw the line with the given set of as measurements and mark Q1 and Q3. Draw a both between Q1 and Q3, then draw Q2 as middle line. The box plot can be draw in horizontal also.
