ALG 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 shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

Front

What does the 'whisker' represent in a Box and Whisker Plot?

Back

The 'whisker' represents the range of the data outside the interquartile range (IQR), extending from the minimum value to Q1 and from Q3 to the maximum value.

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

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

Back

The median is the middle value of the dataset when it is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle values.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the median of the lower half of the dataset, representing the 25th percentile.

Front

What is the upper quartile (Q3)?

Back

The upper quartile (Q3) is the median of the upper half of the dataset, representing the 75th percentile.

Front

What does a Box and Whisker Plot help to identify?

Back

A Box and Whisker Plot helps to identify the spread, center, and skewness of the data, as well as potential outliers.

Front

What is an outlier in a Box and Whisker Plot?

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 determine the maximum value from a Box and Whisker Plot?

Back

The maximum value is the highest point on the plot, located at the end of the upper whisker.

Front

How can you determine the minimum value from a Box and Whisker Plot?

Back

The minimum value is the lowest point on the plot, located at the end of the lower whisker.
