Front

What does it mean if a data set has more than one mode?

Back

If a data set has more than one mode, it is called multimodal, indicating that multiple values appear with the highest frequency.

Front

How do you find the median in an odd-numbered data set?

Back

To find the median in an odd-numbered data set, order the values and select the middle value.

Front

How do you find the median in an even-numbered data set?
