Question

FIST PERSON WHO ANSWERS THIS RECEIVES 30 POINTS!!

What is the mean, median, and mode for this data set: 1,7,12,32,5

Answer 1

To find the mean, sum up {1,7,12,32,5} (the sum is 57) and divide the result by the count of these numbers (5): 57/5, or 11.4.

To find the median, arrange the set of numbers in ascending order: {1, 5, 7, 12, 32}. Now pick out the middle number: It is 7. This is the median of the data.

The mode is the number that shows up most frequently. In this problem, none of the numbers show up more than once, so this data has no mode.

Summary: mean: 11.4; median: 7

Answer 2

Mean: 11.4

Median: 7

Mode: there isn't one

Mean: 1+5+7+12+32=57 57÷5=11.4

Median: 1, 5, 7, 12, 32. 7 is the middle number.

Mode: there isnt a number that repeats itself.
