What is the median of a data set?

Back

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of the data set, representing the 25th percentile.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of the data set, representing the 75th percentile.

Front

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

Back

To find the median, order the data from least to greatest and select the middle value.

Front

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

Back

To find the median, order the data from least to greatest and calculate the average of the two middle values.
