First thing’s first…
What is the definition of
Mean
Median
Mode
Range
Mean
Mean means average!
Add a set of numbers and then
divide by the amount of numbers in
that set
Median
Medians in the middle!
Put the set of numbers in
numerical order and find the
number in the middle of the set.
Mode
Mode is most!
The number that appears the most
often in a set of data
Range
Range is the difference!
Take the smallest value in a set of
data and subtract it from the largest
value.
Let’s try it out…
Find the mean, median, mode, and range for
7, 12, 3, 6, 2, 12, 9, 17, 4
Mean:
7 + 12 + 3 + 6 + 2 + 12 + 9 + 17 + 4 = 72
72 ÷ 9 = 8
The mean of the set is 8.
Find the mean, median, mode, and range for
7, 12, 3, 6, 2, 12, 9, 17, 4
Median:
2, 3, 4, 6, 7, 9, 12, 12, 17
The media of the set is 7.
Don’t forget to put the numbers in numerical
order!!
Find the mean, median, mode, and range for
7, 12, 3, 6, 2, 12, 9, 17, 4
Mode:
12 is the only number that appears more than
once in this set.
Therefore, the mode is 12.
Find the mean, median, mode, and range for
7, 12, 3, 6, 2, 12, 9, 17, 4
Range:
Ask yourself two questions
1.What is the largest number?
2.What is the smallest number?
Subtract the smaller one from the larger one.
17 – 2 = 15
The range of this set is 15.
Lets try another one…
Find the mean, median, mode, & range
13, 13, 16, 2, 4, 8, 12, 15, 1, 10
13, 13, 16, 2, 4, 8, 12, 15, 1, 10
Mean: 9.4
13 + 13 + 16 + 2 + 4 + 8 + 12 + 15 + 1 + 10 = 94
94 ÷ 10 = 9.4
Median: There are two numbers in
the middle! Now what??
Take the numbers and average them.
10 + 13 = 23
23 ÷ 2 = 11.5
13, 13, 16, 2, 4, 8, 12, 15, 1, 10
Mode: 13
It is okay to have more than one mode if
multiple numbers appear more than once.
Range: 14

Gummy Bears
Let’s find the mean,
median, and mode for
your team’s bag of
gummy bears.
Collect your data!
Red
White
Orange
Yellow
Green
Mean
What would guess
the mean color of
gummy bears in
your bag is?
Now find the
actual mean.
Count the number
of bears of each
color to calculate
the average.
Median
Put your numbers in order to find the
median of gummy bear colors
Mode
What color do
think appears
most often?
Find the actual
mode.
Remember!
Mode is the
number that
appears most
often.
Range
What is the range of the number set you
created using the gummy bears?
Largest number – smaller number = range
