Measures of Central Tendency and Finding Missing Values

Harley surveyed his classmates about how many siblings they have and got the following data: 0, 1, 3, 5, 4, 2, 2, 9, 1, 2, 0, 1, 1, 1, 1, 3  Which  measure is best measure of center of the data?

• Mean

• Median

• Mode

• Range

Find the median of these numbers:
4, 2, 7, 4, 3

• 2

• 5

• 7

• 4

In the last 5 games, Kevin Durant scored 22, 22, 18, 12, and 21 points. What is Durant's Mean (Average) score per game?

•  19 points per game

• 95 points per game

• 18.6 points per game

• 22 points per game

What is the mode of the scores?

• 24

• 14

• 34

• 30

What measure of central tendency (mean, median or mode) would be best for the following set of data?
0, 89, 92, 97, 99, 100

• Mode, because it is the one that shows up the most.

• Median, because there is an outlier.  The outlier could be incorrect and would influence the mean too much.

• Mean, because there is not an outlier.  You should always use the mean.

• There is not a best measure of central tendency for this data.

Find the median: 12, 15, 13, 18, 23, 5?

• 14

• 16

• 16.5

• 18

What is the mode in the following numbers? [3, 24, 3, 7, 30, 1, 3, 7, 3]

• 3 and 7 both are modes

• 1 and 7 both are modes

• 3 only

• 7 only

When you are trying to find the MEDIAN of a set of data and 2 numbers are left in the middle after putting them in order from least to greatest, what do you do?

• List both of the numbers as the Median.

• Add the two numbers together and divide by 2.

• Pick the one that you want.

• Subtract the two numbers.

The number of miles that Jenna cycled each week for a 7-week period is shown:

36, 42, 28, 52, 48, 36, 31

What is the median number of miles Jenna cycled?

• 24

• 39

• 36

• 52

What is the median?

• The number in the middle when the numbers are in order from least to greatest.

• The difference between the largest and smallest number.

• The average

• The number that appears most often.
