3. The median of a data set is the middle value when the
values are written in numerical order. If a data set
has an even number of values, the median is the
mean of the two middle values.
Minimum monthly temperatures (C) for Big
Delta, Alaska.
-24, -21, -17, -7, 3, 8, 11, 8, 2, -8, -18, -23
What is the median of the data set?
-24, -23, -21, -18, -17, -8, -7, 2, 3, 8, 8, 11
-7.5
4. The mode of a data set is the value that occurs
most often. A data set can have no mode, one
mode, or more than one mode.
Minimum monthly temperatures (C) for Big
Delta, Alaska.
-24, -21, -17, -7, 3, 8, 11, 8, 2, -8, -18, -23
What is the mode of the data?
8
5. The range of a data set is the difference of the
greatest value and the least value.
Minimum monthly temperatures (C) for Big
Delta, Alaska.
-24, -21, -17, -7, 3, 8, 11, 8, 2, -8, -18, -23
What is the range of the data set?
11 – (-24) = 350 C
6. Here are some scores from a card game:
154, 113, 172, 161, 145
Find the mean, median, mode, and range of the data
set.
Mean = 149 Median = 154
Mode = no mode Range = 59
If the scores were doubled, what would happen to the
mean, median, mode, and range?
They would all double.
