Box Plots

Front

What is a box plot?

Back

A box plot, or 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 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. It measures the spread of the middle 50% of the data.

Front

How do you find the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What does the maximum value represent in a box plot?

Back

The maximum value is the largest number in the dataset, represented by the rightmost point in the box plot.

Front

What is the purpose of the whiskers in a box plot?

Back

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

Front

How can you identify the median from a box plot?

Back

The median is represented by the line inside the box of the box plot.

Front

What does a higher median indicate about a dataset?

Back

A higher median indicates that the central tendency of the dataset is higher, meaning that more data points are above the lower half of the dataset.

Front

What is the first quartile (Q1)?

Back

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

Front

What is the third quartile (Q3)?

Back

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