What's on a Grade 12 mean, median, mode & range worksheet?

Each pack has up to 12 questions per page with a matching answer key, tuned to Grade 12, with beginner, intermediate, and advanced options so you can match the child's level.

What is the difference between mean and median?

The mean is the average (sum ÷ count); the median is the middle value once the data is sorted.

How do you find the mode?

Find the value that appears most often in the list. A data set can have no mode (every value is unique) or more than one (a tie for most frequent).

How do you find the range?

Subtract the smallest value from the largest.

What is standard deviation?

A measure of how spread out a data set is: find the mean, square each value's distance from it, average those (dividing by n−1 for a sample), then take the square root.
