Explanation:
Eliminating the lowest value, -6, from the data set will have the following effect on the mean (average):
Original data set:
-6, 3, 3, 3, 3, 5, 6, 6, 8, 10
Calculate the mean of the original data set:
Mean = (Sum of all values) / (Number of values)
Mean = (-6 + 3 + 3 + 3 + 3 + 5 + 6 + 6 + 8 + 10) / 10
Mean = 39 / 10
Mean = 3.9
Eliminate the lowest value (-6) from the data set:
New data set: 3, 3, 3, 3, 5, 6, 6, 8, 10
Calculate the mean of the new data set:
Mean = (Sum of all values) / (Number of values)
Mean = (3 + 3 + 3 + 3 + 5 + 6 + 6 + 8 + 10) / 9
Mean = 45 / 9
Mean = 5
So, eliminating the lowest value (-6) from the data set increases the mean from 3.9 to 5.
