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.

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.

How do you find the lower quartile (Q1)?

Back

The lower quartile (Q1) is found by determining the median of the lower half of the dataset.

What does the interquartile range (IQR) represent?

Back

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

What does the whisker in a box plot represent?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, showing the range of the data.

How can you determine the range of a dataset from a box plot?

Back

The range of a dataset can be determined by subtracting the minimum value from the maximum value.

What does it mean if a box plot is skewed to the right?

Back

If a box plot is skewed to the right, it indicates that there are a few high values that are pulling the median and quartiles to the right.
