Median = 8.8
Mode: does not exist
Best Measure: mean
Substitute values
Add terms
Calculate quotient
To identify the median, we observe the middle value. 8.2, 8.5, 8.8, 9, 9.3 We can see that the middle value in this set is 8.8, so this is our median.
The mode of a data set is the value that occurs most frequently. 8.2, 8.5, 8.8, 9, 9.3 In this set, each number in this set occurs only once. Therefore, there is no mode.
For the given scenario, the best measure is the mean because there are no outliers in the data. Moreover, mean and median are almost equal.
