Box Plots Practice

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 dataset?

Back

The median is the middle value when the data is arranged in ascending order.

Front

How do you find the maximum value in a dataset?

Back

The maximum value is the largest number in the dataset.

Front

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What are quartiles in a box plot?

Back

Quartiles divide the dataset into four equal parts: Q1 (first quartile), Q2 (median), and Q3 (third quartile).

Front

How do you calculate the median if there are two middle numbers?

Back

Add the two middle numbers and divide by two.

Front

What does the interquartile range (IQR) represent?

Back

The IQR is the range between the first quartile (Q1) and the third quartile (Q3) and shows the spread of the middle 50% of the data.

Front

What is the purpose of a box plot?

Back

A box plot visually summarizes the distribution of a dataset and highlights its central tendency and variability.

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 a box plot tell you about outliers?

Back

Outliers are data points that fall outside the range of the whiskers in a box plot.
