Mean : Average. Add up all the numbers and divide by how many there are. Ex. 1,2,3. 6/3=2. The mean is 2.

Median: Middle number in the set. Organize the info from smallest to greatest and choose the number that is in the middle. If two middle numbers, add both and divide by 2.

Mode: Number that appears the most

Range: The difference between the greatest and least number in the set. Ex. 1, 5, 100. 100-1=99. range is 99

Interquartile Range: A measure of spread equal to the upper quartile minus the lower quartile.

Answer:

Find the median.

Calculate the median of both the lower and upper half of the data.

The IQR is the difference between the upper and lower medians.
