What is the five number summary for this data set?

MrRa [10]

Answer:

see explanation

Step-by-step explanation:

The median is the middle value of the data set in ascending order. If there is no exact middle then the median is the average of the values either side of the middle.

Given

3 8 14 19 22 29 33 37 43 49

↑ middle is between 22 and 29

median = $\frac{22+29}{2}$ = $\frac{51}{2}$ = 25.5

The upper quartile $Q_{3}$ is the middle value of the data to the right of the median.

29 33 37 43 49

↑

$Q_{3}$ = 37

The lower quartile $Q_{1}$ is the middle value of the data to the left of the median.

3 8 14 19 22

↑

$Q_{1}$ = 14

The min is the smallest value in the data set, that is 3

The max is the largest value in the data set, that is 49

The 5 number summary is

3, 14, 25.5, 37, 49

Mumz [18]

Answer:

It's not, the Median is 5 the mean is 10!

Step-by-step explanation:

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
