Question

HELP I HAVE TEN MINS TO FINISH THIS

Answer 1

Step-by-step explanation:

I just answered exactly that question.

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The median is the middle value when a data set is ordered from least to greatest.

If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

so, mean (average)

(10+10+18+18+10+5+12+13)/8 = 96/8 = 12

for the median we sort the data entries

5 10 10 10 12 13 18 18

we habe an even number of entries so we need to calculate the mean of the two middle numbers 10 and 12 :

(10+12)/2 = 22/2 = 11
