How do you find the minimum value in a box plot?

Back

The minimum value is represented by the leftmost point of the box plot.

Front

What does the maximum value indicate in a box plot?

Back

The maximum value is represented by the rightmost point of the box plot.

Front

What are quartiles in a box plot?

Back

Quartiles are values that divide a dataset into four equal parts: Q1 (first quartile), Q2 (median), and Q3 (third quartile).

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), representing the middle 50% of the data.

Front

How is the median calculated from a box plot?

Back

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

Front

What does a longer box in a box plot indicate?

Back

A longer box indicates a larger interquartile range (IQR), suggesting more variability in the middle 50% of the data.

Front

What does a box plot tell us about data distribution?

Back

A box plot provides insights into the data's central tendency, variability, and potential outliers.

Front

What are outliers in a box plot?

Back

Outliers are data points that fall significantly outside the range of the box plot, often represented as individual points.
