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 median represent in a dataset?

Back

The median is the middle value of a dataset when it is ordered from least to greatest. It divides the dataset into two equal halves.

Front

What is the interquartile range (IQR)?

Back

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

Front

How do you find the median of a dataset?

Back

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

Front

What does the term 'quartile' refer to?

Back

A quartile is a type of quantile that divides a dataset into four equal parts, with Q1 being the first 25%, Q2 the median (50%), and Q3 the 75%.

Front

What is the purpose of a Box and Whisker Plot?

Back

The purpose of a Box and Whisker Plot is to visually summarize the distribution of a dataset, highlighting 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

How can you determine the spread of a dataset using a Box and Whisker Plot?

Back

The spread of a dataset can be determined by looking at the length of the box (IQR) and the length of the whiskers, which indicate variability.

Front

What does a longer IQR indicate about a dataset?

Back

A longer IQR indicates greater variability in the middle 50% of the data, while a shorter IQR suggests less variability.

Front

How do you interpret the median in a Box and Whisker Plot?

Back

The median is represented by a line inside the box of the Box and Whisker Plot, indicating the central value of the dataset.
