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 (Q1), median, third quartile (Q3), and maximum values.

Front

What does IQR stand for?

Back

IQR stands for Interquartile Range, which is the difference between the third quartile (Q3) and the first quartile (Q1) in a dataset.

Front

How do you find the median in a box plot?

Back

The median is the line inside the box of the box plot, representing the middle value of the dataset.

Front

What does the upper 25% of a box plot represent?

Back

The upper 25% of a box plot represents the values above the third quartile (Q3), indicating the highest quarter of the data.

Front

What is the purpose of comparing box plots?

Back

Comparing box plots helps to analyze and understand the differences in distributions, variability, and central tendencies of different datasets.

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, as it represents a larger interquartile range (IQR).

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 value of both datasets is the same, but their variability may differ.

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 outside the interquartile range.

Front

How can you tell which group has more variability from box plots?

Back

You can tell which group has more variability by comparing the lengths of the boxes and the whiskers; a longer box or whisker indicates more variability.

Front

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

Back

A box plot skewed to the right indicates that the majority of the data points are concentrated on the left side, with a few higher values stretching the tail to the right.
