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 \(12\) 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 \(62\) 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 \(96\) 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 \(28\) 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).
