Analyzing 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 is the range in a box plot?

Back

The range is the difference between the maximum and minimum values in a dataset.

Front

What do the whiskers 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

What is the interquartile range (IQR)?

Back

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

Front

How do you find the median from a box plot?

Back

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

Front

What does a longer whisker indicate in a box plot?

Back

A longer whisker indicates a greater spread of data points in that direction, suggesting more variability.

Front

What does it mean if a box plot has a larger IQR?

Back

A larger IQR indicates that the middle 50% of the data is more spread out, showing greater variability in that portion of the dataset.

Front

How can you tell if a dataset has outliers from a box plot?

Back

Outliers are typically represented as individual points that fall outside the whiskers of the box plot.

Front

What is the purpose of comparing two box plots?

Back

Comparing two box plots allows you to analyze differences in central tendency, spread, and overall distribution between two datasets.
