What does the median represent in a data set?

Back

The median is the middle value of a data set when it is ordered from least to greatest.

Front

What are quartiles in a data set?

Back

Quartiles are values that divide a data set into four equal parts, with each part representing 25% of the data.

What is the lower quartile (Q1)?

Back

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

The interquartile range (IQR) is found by subtracting the lower quartile (Q1) from the upper quartile (Q3).

Front

What does a box and whisker plot show about outliers?

Back

Outliers are data points that fall significantly outside the range of the other data points, often represented as individual points on the plot.

Front

What percent of data lies between Q1 and Q3?

Back

50% of the data lies between the lower quartile (Q1) and the upper quartile (Q3).

Front

How do you determine the median from a box and whisker plot?

Back

The median is represented by the line inside the box of the box and whisker plot.

Front

What is the purpose of a box and whisker plot?

Back
