Calculate the interquartile range of the following data.
{35, 20, 41, 48, 79, 83, 83, 97, 120}
Q1 = 1.__
Q3 = 2.__
IQR = 3.__
Values lower than 4.__ and higher than
5.__ are considered outliers.
The outliers in this data set is 6.__
match the correct choices to the answers
a. -40
b. -14
c. 14
d. 20
e. 38
f. 52
g. 78
h. 90
i. 120
j. 142
Q1 = 35
Q3 = 83
IQR = 83 - 35 = 48
Values lower than 35 - 1.5(48) = -40 and higher than 83 + 1.5(48) = 142 are considered outliers.
The outliers in this data set is 120
Therefore:
a. -40
b. 120
c. 48
d. 35
e. 83
f. 20
g. 41
h. 79
i. 97
j. 98
