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.

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) represents 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 calculate the median of a dataset?

Back

To calculate the median, arrange the data in ascending order and find the middle value. If there is an even number of values, average the two middle values.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

What does a box plot visually represent?

Back

A box plot visually represents the distribution of a dataset, highlighting its central tendency and variability.

Front

What is the first quartile (Q1)?

Back

The first quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What is the third quartile (Q3)?

Back

The third quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

How do you find the interquartile range (IQR)?

Back

To find the IQR, subtract the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

Front

What is the purpose of a box plot?

Back

The purpose of a box plot is to summarize a dataset and identify outliers, as well as to compare distributions between different datasets.
