Box-and-Whisker Plot

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 minimum value represent in a Box-and-Whisker Plot?

Back

The minimum value represents the smallest data point in the dataset.

Front

How is the median defined in a Box-and-Whisker Plot?

Back

The median is the middle value of the dataset when it is ordered from least to greatest.

Front

What is the Interquartile Range (IQR)?

Back

The Interquartile Range (IQR) is the difference between the upper quartile (Q3) and the lower quartile (Q1), representing the range of the middle 50% of the data.

Front

What does the lower quartile (Q1) indicate?

Back

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

Front

What does the upper quartile (Q3) indicate?

Back

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

Front

How do you calculate the Interquartile Range (IQR)?

Back

IQR = Q3 - Q1.

Front

What is the significance of the whiskers in a Box-and-Whisker Plot?

Back

The whiskers extend from the quartiles to the minimum and maximum values, showing the range of the data.

Front

What does a Box-and-Whisker Plot reveal about data distribution?

Back

It provides insights into the central tendency, variability, and potential outliers in the dataset.

Front

How can outliers be identified in a Box-and-Whisker Plot?

Back

Outliers can be identified as data points that fall outside the range defined by Q1 - 1.5*IQR and Q3 + 1.5*IQR.
