Summarizing Data: Mean, Median, Mode, and Range

This video tutorial covers Math 6 Lesson 8-2, focusing on summarizing data using mean, median, mode, and range. It includes examples of ordering data, calculating mean, median, mode, and range, and applying these concepts to real-world scenarios like bowling scores and music libraries. The lesson concludes with a comprehensive example of analyzing wait times and a brief introduction to the next lesson on box plots.

What is the median of the ordered student reading hours?

• 11 hours

• 7 hours

• 12 hours

• 5 hours

If a team's average score increases, what could be the reason?

• A team member scored higher than before

• The number of team members changed

• A team member scored lower than before

• All team members scored the same as before

What is the mean score of Carla's bowling team?

• 95

• 86

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

• Choose the lowest value

• There is no median in even sets

• Average the two middle values

• Choose the highest value

If two numbers are in the middle of a sorted data set, how do you find the median?

• Choose the smaller number

• Find the average of the two

• Choose the larger number

• Add them together

What is the mode in a data set where no values are repeated?

• There is no mode

• The highest value

• All values are the mode

• The lowest value

What is true about the mode of a data set?

• It is always the smallest number

• It is the number that appears most frequently

• It is the difference between the highest and lowest values

• It is the average of all numbers

What does the range of a data set represent?

• The difference between the highest and lowest values

• The most frequent value

• The middle value

• The average value

What is the range of Trey's music library playing times?

• 13 minutes

• 16 minutes

• 59 minutes

• 72 minutes

In a data set, if the mean and median are the same, what does this indicate about the data set?

• It is skewed to the left

• It has a large range

• It has no mode

• It is perfectly symmetrical
