Problems Involving Mean and Median
This lecture series discusses using mean and median to make inferences about data points and how the small changes in data can affect mean and median. Watch the videos and complete the interactive exercises.

Estimating mean and median in data displays - Questions
1. An article reported the ages of 
CEOs:
The approximate location of the median is point (A/B/C).
The approximate location of the mean is point (A/B/C).
2. A meteorologist recorded the daily high temperature in their city for 
consecutive days. Here are the temperatures:
The approximate location of the median is point (A/B/C).
The approximate location of the mean is point (A/B/C).
3. Researchers asked a sample of 
teenagers how much cash they currently had with them. Here is a histogram showing their results:
The approximate location of the median is in interval (A/B/C).
The approximate location of the mean is in interval (A/B/C).
4. A teacher surveyed 
students on how long they each spent on a homework assignment. Here are their responses:
The approximate location of the median is point (A/B/C).
