Box and whisker plots

Front

What is a box and whisker plot?

Back

A box and whisker plot is a graphical representation of a dataset that displays its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

Front

What does the interquartile range (IQR) represent?

Back

The interquartile range (IQR) represents the range of the middle 50% of a dataset, calculated as Q3 - Q1.

Front

How do you find the median of a dataset?

Back

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

Front

What does Q1 represent in a box and whisker plot?

Back

Q1, or the first quartile, represents the value below which 25% of the data falls.

Front

What does Q3 represent in a box and whisker plot?

Back

Q3, or the third quartile, represents the value below which 75% of the data falls.

Front

How do you calculate the IQR?

Back

The IQR is calculated by subtracting Q1 from Q3 (IQR = Q3 - Q1).

Front

What is the purpose of a box and whisker plot?

Back

The purpose of a box and whisker plot is to summarize a dataset and show its distribution, including its central tendency and variability.

Front

What does the whisker in a box and whisker plot represent?

Back

The whiskers in a box and whisker plot extend from the quartiles to the minimum and maximum values, showing the range of the data.

Front

If a box and whisker plot shows a longer whisker on one side, what does it indicate?

Back

A longer whisker on one side indicates greater variability or spread in the data on that side.

Front

What is the significance of the median in a box and whisker plot?

Back

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