To find: the measurement of central tendency best represents the data.
Answer to Problem 13PPS
Mean would best to represent the data.
Explanation of Solution
Given information:
The graph shows the number of siblings that Ms. D’s students have.
Calculation:
As per the graph, data has given for the number of students have 1-5 sibling respectively.
3, 7, 8, 5, 2, 1
Arrange the data in ascending order for better understanding.
1, 2, 3, 5, 7, 8
Below definitions will help to determine the best measure of central tendency.
Measure | When to use |
Mean | Data have no extreme value |
Median | Data have extreme value. No big gap in the mid of the data. |
Mode | Many repetitive values in the data. |
From the data we can see that there is no mode, and there is no extreme values as well hence Mean would best to represent the data.
