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.
