Box Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a dataset that displays the 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, and the third quartile (Q3) is the median of the upper half.

Front

What does the range of a dataset indicate?

Back

The range is the difference between the maximum and minimum values in a dataset, showing the spread of the data.

Front

How do you calculate the mean of a dataset?

Back

The mean is calculated by adding all the values in the dataset and dividing by the number of values.

Front

What do points B and D represent on the box plot?

Back

Points B and D represent the first quartile (Q1) and third quartile (Q3), respectively.

Front

What is the interquartile range (IQR)?

Back

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

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in a dataset.

Front

What is the maximum value in a dataset?

Back

The maximum value is the largest number in a dataset.

Front

How do you find the middle 50% of a dataset using a box plot?

Back

The middle 50% of a dataset is represented by the interquartile range (IQR), which is the area between Q1 and Q3 on the box plot.
