What is the purpose of a median in statistics?

Back

The median provides a measure of central tendency that is less affected by outliers than the mean.

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

Front

What does it mean if a box plot has a long whisker?

Back

A long whisker in a box plot indicates a larger spread of data points in that direction, suggesting the presence of outliers.

Front

How do you determine the median from a box plot?

Back

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

Front

What is the difference between mean and median?

Back

The mean is the average of all data points, while the median is the middle value when data points are ordered.
