This list represents the number of minutes 13 people spend watching television each day.

{22, 30, 30, 36, 37, 38, 39, 45, 45, 48, 55, 60, 120 }

What are the mean and median of this data set? Round any decimals to the nearest tenth.

Mean = [?]

Median = [?]

Compare the values of mean and median to determine whether the data is symmetric or skewed. Interpret the shape in relation to the context.

Use the drop-down arrows to complete the sentences.

The data is [skewed-left, skewed-right, symmetric], which means that compared to the mean, [many, few] people spend more time than average watching television.

The median of a list of numbers is the number that is in the middle of the list from least to greatest, which is easy to calculate if odd (we do not have to worry about an even amount of numbers since we are dealing with an odd list), in this case, the median is 39 since it has six values before and after it.

What do skewed and symmetric mean?

Symmetric means that the mean and median are equal, whereas skewed means that they are not. A graph can be either skewed left or skewed right. Skewed left means that more people are a lower amount (in say minutes of TV watched ever) than the mean, meaning that the median is going to be left of or less than the mean.

Skewed right means that more people are a higher amount than the mean, meaning that the median is right of or greater than the mean.

Comparing the mean and median, the mean is 46.5 and the median is 39, which means the data is skewed left since the median is less than the mean. This tells us that there are few people who spend more time than average watching TV.
