Part (a) Make a box and whisker plot
Part (b) Identify outliners. Remove them and redraw the box and whisker diagram
Part (c) How does the removal of outliners effect box and whisker plot? How does is effect the median of the set?
Answer:
Given below with explanations
Step-by-step explanation:
(a)
The data is first arranged in ascending order:
1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42
Total values = 16
Minimum value = 1
Maximum value = 42
Lower Quartile = 1/4 x 16 = 4th value = 7 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42)
Upper Quartile = 3/4 x 16 = 12th value = 16 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42)
Median = 1/2 x 16 = 8th value = 9 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23, 38, 42)
The Box and whisker plot is attached in the picture below:
(b)
Outliners are 38 and 42
1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23
Total values = 14
Minimum value = 1
Maximum value = 23
Lower Quartile = 1/4 x 14 = 3.5th value = 6 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23)
(5+7)/2
Upper Quartile = 3/4 x 14 = 10.5th value = 14.5 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23)
(14+15)/2
Median = 1/2 x 14 = 7th value = 9 (1, 3, 5, 7, 8, 8, 9, 9, 11, 14, 15, 16, 16, 23)
The Box and whisker plot is attached in the picture below:
(c)
The lower and upper quartile values have changed after removing the outliners but the median remains same in this case
