Khalid’s bowling scores are show in the table - Find the mean, median , mode , and range of the data . Round to the nearest tenth.

Mean: 149.9
Median: 157.5
Mode: 162
Range: 36

Mean is the average of all the scores.
128 + 130 + 138 + 157 + 158 + 162 + 162 + 164 = 1199
Divide that by the number of games (8) and the mean is 1199/8 = 149.875
Rounded = 149.9

Median is the middle number of a data set, or the average of the two middle numbers when there is an even number of entries in the data set. The data entries have to be written in ascending order for median.

128, 130, 138, 157, 158, 162, 162, 164
I spaced things out to isolate the two middle numbers. 157 + 158 = 315
315/2 = 157.5
———————
Mode is the number that occurs most often in the data set. The only number that shows up more than once in the set is 162. That is your mode.
——————-
Range is the result of your lowest number subtracted from your highest number.

164 - 128 = 36
