Question

Find the mean, meadian, mode and range for each set of data 6, 9, 2, 4, 3, 6, 5

Answer 1

mean = sum of all digits / number of digits = ( 2+3+ 4 +5+ 6+6+9) / 7= 35/7 =5

median - put the numbers in order 2 , 3, 4, 5, 6, 6, 9 which one is in the middle - = 5

mode = most = 6 ( the number that occurs the most )

Explanation:

Answer 2

Mean: Add up the numbers and divide the sum by the number of values in the set.

6 + 9 + 2 + 4 + 3 + 6 + 5 = 35

35 / 7 = 5

Median: Sort the set from the smallest value to the largest value and select the number in the middle. If the count of the set if even, then select the two middle values and take their mean average.

2, 3, 4, 5, 6, 6, 9

^

So, the median average is 5.

Mode: What number appears the most frequently?

The mode of the set is 6 because it appears twice.

Range: Sort the set by ascending order and take the smallest value and subtract that from the largest value in the set.

9 - 2 = 7

The range is 7.
