What is a box plot?

Back

A box plot is a graphical representation of a dataset that shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

What does the median represent in a box plot?

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

How do you determine the range of a dataset from a box plot?

Back

The range is calculated by subtracting the minimum value from the maximum value.

Front

What does Q1 represent in a box plot?

Back

Q1, or the first quartile, represents the value below which 25% of the data falls.

Front

What does Q3 represent in a box plot?

Back

Q3, or the third quartile, represents the value below which 75% of the data falls.

Front

How can you compare medians from two box plots?

Back

You can compare the horizontal line within each box plot; the higher line indicates a greater median.

Front

What does the whisker in a box plot indicate?

Back

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

Front

What does it mean if two box plots overlap?

Back

If two box plots overlap, it suggests that the datasets may have similar distributions or ranges.

Front

How can you identify outliers in a box plot?

Back

Outliers are typically represented as individual points that fall outside the whiskers of the box plot.

Front

What is the significance of the interquartile range (IQR)?

Back

The IQR is the range between Q1 and Q3 and measures the spread of the middle 50% of the data.
