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 values.

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, dividing the dataset into two equal halves.

Front

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.

Front

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

Back

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

Front

What does a longer box in a box plot indicate?

Back

A longer box indicates greater variability in the middle 50% of the data.

Front

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.

Front

How can you compare two box plots?

Back

You can compare the medians, ranges, and the spread of the data (variability) between the two groups.

Front

What does it mean if one box plot is higher than another?

Back

If one box plot is higher, it indicates that the median of that group is greater than the median of the other group.

Front

What is an outlier in the context of box plots?

Back

An outlier is a data point that lies significantly outside the range of the other data points, often represented as individual points beyond the whiskers.

Front

What is the purpose of using box plots?

Back

Box plots are used to visually summarize and compare distributions of datasets, highlighting differences in medians and variability.
