Find the mean, median and mode for each set of values.

Question

1,1,3,3,5,5,6,7,9,9,9,10,10

Answer 1

Mean: (1+1+3+3+5+5+6+7+9+9+9+10+10)/13 = 69/13 ≈ 5,31

Median: There are 13 numbers, so the median is the middle number when they are listed in order. Putting them in order, we get: 1,1,3,3,5,5,6,7,9,9,9,10,10. Thus, the median is 5.

Mode: The mode is the number that appears most frequently. In this set, both 9 and 10 appear three times, and they are the most frequent values. Therefore, the mode is 9 and 10.
