What is another word for AVERAGE?

• Mode

• Median

• Mean

• Not nice

Answer explanation

The term 'mean' is commonly used to refer to the average of a set of numbers. While 'mode' and 'median' are also measures of central tendency, they are not synonymous with 'average'. Therefore, 'mean' is the correct answer.

What is the MEDIAN of this set of data?

10, 90, 80, 60, 50, 40, 70, 30, 20, 100

• 50

• 60

• 55

• 45

Answer explanation

To find the median, first sort the data: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. With 10 numbers, the median is the average of the 5th and 6th values (50 and 60), which is (50+60)/2 = 55.

What is the range?

• The sum of the largest and smallest number

• The number in the middle

• The difference between the largest and smallest number

• The number that appears most often

Answer explanation

The range is defined as the difference between the largest and smallest number in a set. This means you subtract the smallest value from the largest value, making the correct choice the difference between the largest and smallest number.
