Answer:
Minimum value = 43, ,
,
, Maximum value = 69.
Distribution is negative skewed.
Step-by-step explanation:
The given data set is
44, 43, 67, 68, 57, 65, 52, 62, 69, 54, 53, 61, 67, 48, 65
Arrange the data in ascending order
43, 44, 48, 52, 53, 54, 57, 61, 62, 65, 65, 67, 67, 68, 69
Divide the data in 4 equal parts.
(43, 44, 48), 52, (53, 54, 57), 61, (62, 65, 65), 67, (67, 68, 69)
Minimum value = 43
Maximum value = 69
Starting and end point of box plot represent the minimum and maximum value respectively. Box starts from the first quartile to the third quartile. A vertical line goes through the box at the median.
The shape of the distribution.
Normally distributed: If
Positive skew: If
Negative skew: If
For the given data set
Since , therefore the given distribution is negative skewed.
