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 range in a dataset represent?

Back

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

Front

How do you calculate the Interquartile Range (IQR)?

Back

IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3): IQR = Q3 - Q1.

Front

What does the median represent in a dataset?

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 is the purpose of a Box and Whisker Plot?

Back

The purpose is to summarize a dataset visually, showing its central tendency, variability, and potential outliers.

Front

What does a longer whisker in a Box and Whisker Plot indicate?

Back

A longer whisker indicates a greater spread of data points outside the quartiles, suggesting more variability in the dataset.

Front

What is an outlier in the context of Box and Whisker Plots?

Back

An outlier is a data point that lies significantly outside the range of the other data points, often represented as individual points beyond the whiskers.

Front

How can you identify the median from a Box and Whisker Plot?

Back

The median is represented by the line inside the box of the Box and Whisker Plot.

Front

What does Q1 represent in a Box and Whisker Plot?

Back

Q1, or the first quartile, represents the median of the lower half of the dataset, indicating that 25% of the data points fall below this value.

Front

What does Q3 represent in a Box and Whisker Plot?

Back

Q3, or the third quartile, represents the median of the upper half of the dataset, indicating that 75% of the data points fall below this value.
