Comparing Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile, median, third quartile, and maximum.

Front

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.

Front

What are quartiles in a box plot?

Back

Quartiles are values that divide a dataset into four equal parts, with the first quartile (Q1) being the 25th percentile, the second quartile (Q2) the 50th percentile (median), and the third quartile (Q3) the 75th percentile.

Front

What does the interquartile range (IQR) measure?

Back

The interquartile range (IQR) measures the spread of the middle 50% of a dataset, calculated as Q3 - Q1.

Front

How do you determine the spread of a dataset using a box plot?

Back

The spread of a dataset can be determined by looking at the range (maximum - minimum) and the interquartile range (IQR).

Front

What do points A and E represent on a box plot?

Back

Points A and E represent the least and greatest values in the dataset, respectively.

Front

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

Back

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

Front

How can you compare two box plots?

Back

You can compare two box plots by looking at their medians, spreads (IQRs), and overall ranges.

Front

What does a larger interquartile range indicate?

Back

A larger interquartile range indicates a greater spread of the middle 50% of the data.

Front

What does it mean if two box plots have the same median?

Back

If two box plots have the same median, it means that the central tendency of the two datasets is the same.
