Answer 1

a

Explanation:

Mode refers to a value that appears most frequently in a data set.

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Median is the number that occurs in the middle of a set of observations

Arranging the numbers in ascending order : 55, 66, 82, 89, 90, 92

median = (82 + 89) / 2 = 85.5

There is no mode because the numbers only appear once

Range = 92 - 55 = 37

mean = 476/6 = 79
