What is a box plot?

Back

A box plot, or box-and-whisker plot, is a graphical representation of a dataset that displays its minimum, first quartile, median, third quartile, and maximum.

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

How do you find the minimum value in a dataset?

Back

The minimum value is the smallest number in the dataset.

Front

What is the range of a dataset?

Back

The range is the difference between the maximum and minimum values in a dataset.

Front

How do you calculate the median of an even set of numbers?

Back

To find the median of an even set, average the two middle numbers after sorting the dataset.

Front

What is a quartile in statistics?

Back

A quartile is a type of quantile that divides a dataset into four equal parts.

Front

What does the first quartile (Q1) represent?

Back

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

Front

What does the third quartile (Q3) represent?

Back

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

Front

How do you interpret the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between Q3 and Q1, representing the range of the middle 50% of the data.

Front

What is the purpose of a box plot?

Back

A box plot is used to visually summarize the distribution of a dataset, highlighting its central tendency and variability.
