We have the next data
19, 15, 97, 89, 20, 4, 47, 6, 95, 66, 22
a) mean
we need to sum all the numbers in the data and then divided by the 11 (number of numbers)
19 +15 +97+ 89+ 20+ 4+ 47+ 6+ 95+66 +22= 480
480/11=43.63
the mean of the set is 43.63
b) median
For the median, we need to reorder the number from the smaller to the bigger
4,6,15,19,20,22,47,66,89,95,97
the median is 22
c) mode
there isn't any value that is repeated so we don't have mode
d) midrange
In order to calculate the midrange we need the greatest number of the set and the least value of the set in this case
greatest =97
least =4
