Statistical Measures: Mean, Median, Mode

Miss Thompson introduces measures of center, including mean, median, and mode, and explains how to calculate each. The video also covers the concept of range as a measure of variability. Students are guided through practice problems to reinforce their understanding of these statistical concepts.

What is the mean of the data set {15, 7, 24, 13, 21}?

• 16

• 18

• 20

• 22

If you have the data set {5, 7, 2, 3, 5, 8, 12, 14}, what is the mean?

• 7

• 5

• 11

• 9

How do you find the median of a data set with an odd number of values?

• Find the average of all values

• Subtract the smallest value from the largest value

• Find the middle value after ordering the data

• Find the most frequently occurring value

For the data set {7, 13, 15, 21, 24}, what is the median?

• 15

• 24

• 13

• 21

What is the median of the data set {2, 3, 5, 5, 7, 8, 12, 14}?

• 6

• 5

• 7

• 8

How do you determine the mode of a data set?

• Find the middle value after ordering the data

• Subtract the smallest value from the largest value

• Find the average of all values

If a data set has no repeating values, what is the mode?

• 1

• No mode

• 0

• All values are modes

What is the range of the data set {7, 13, 15, 21, 24}?

• 7

• 13

• 17
