Focus: Outcomes and Measures of Center
5.16 The student will
a) describe mean, median, and mode as measures
of center;
c) find the mean, median, mode, and range of a set
of data; and
d)describe the range of a set of data as a measure
of variation.
Objectives
• The students will find the mean, median,
mode, and range of a set of data.
• The students will describe mean, median, and
mode as measures of center.
Pretend you have a set of data…
Now what? What does it mean?
Mean, median, mode, and range will help you
understand what the data means!

Data Set: 9, 16, 17, 17, 18, 20, 22
• Mean: Add all the numbers together, then
divide by how many numbers there are
9+16+17+17+18+20+22=119 and there are 7 numbers, so 119÷7= 17
• Median: When the data is in order, the
number in the middle
9, 16, 17,
17, 18, 20, 22
Extra Help
Data Set: 9, 16, 17, 17, 18, 20, 22
• Mode: The number repeated the most
(There may not be a mode,
or there may be more than one)
17, because it is listed twice
• Range: Subtract the smallest number from the
largest number
22-9= 13
