To find the deviation of a set of numbers, you need to calculate the difference between each number and the mean of the set.
Step 1: Calculate the mean of the set. -3 + 1 + 2 + 4 = 4 4 / 4 = 1
The mean of the set is 1.
Step 2: Calculate the deviation of each number from the mean. |-3 - 1| = 4 |1 - 1| = 0 |2 - 1| = 1 |4 - 1| = 3
The deviations are 4, 0, 1, and 3.
Therefore, the deviation of the numbers -3, 1, 2, and 4 from the mean is 4, 0, 1, and 3 respectively.
