What does the median represent in a box plot?

Back

The median is the middle value of a dataset when it is ordered from least to greatest, dividing the dataset into two equal halves.

How do you find the range of a dataset using a box plot?

Back

The range is found by subtracting the minimum value from the maximum value in the dataset.

What are quartiles in a box plot?

Back

Quartiles are values that divide a dataset into four equal parts: the first quartile (Q1) is the median of the lower half, the second quartile (Q2) is the median, and the third quartile (Q3) is the median of the upper half.

What does the whisker in a box plot represent?

Back

The whiskers extend from the box to the smallest and largest values that are not outliers, showing the spread of the data.

How can you identify outliers in a box plot?

Back

Outliers are typically represented as individual points that fall outside the range defined by 1.5 times the interquartile range (IQR) above Q3 and below Q1.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.

How do you interpret the median from a box plot?

Back

The median is represented by a line inside the box of the box plot, indicating the central tendency of the data.

What is the significance of the box in a box plot?

Back

The box represents the interquartile range (IQR), showing where the central 50% of the data lies.

If a box plot has a longer whisker on one side, what does it indicate?

Back

A longer whisker on one side indicates a greater spread of data on that side, suggesting more variability in the values.
