Answer:
Mean = [tex]30.7[/tex]
Median = [tex]34[/tex]
Mode = no mode
Step-by-step explanation:
To find the mean:
Step 1. Arrange the set of data points from least to greatest: [tex]15, 22, 29, 34, 37, 38, 40[/tex]
Step 2. Add up all of the data points and use division to get the average. NOTE: Divide the sum according to the number of data points given. In this case, use [tex]7[/tex] since there are [tex]7[/tex] numbers given in the set.
Therefore, the mean for the given set is [tex]30.7[/tex].
To find the median:
Step 1. Arrange the set of data points: [tex]15, 22, 29, 34, 37, 38, 40[/tex]
Step 2. If a set of data points are odd, then the middle one will be the median. If a set of data points are even, then the average of the two numbers will be the median of the set. In this problem, [tex]34[/tex] is our median.
To find the mode:
Step 1. Arrange: [tex]15, 22, 29, 34, 37, 38, 40[/tex]
Step 2. Cancel out ALL of the similar numbers. But what if there's NO repeating numbers? Then, there's no mode in the set.
