Front

What is the median?

Back

The median is the middle value in a set of data when arranged in ascending order. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What is the maximum value in a data set?

Back

The maximum value is the largest number in a set of data.

Front

What does a box and whisker plot represent?

Back

A box and whisker plot visually displays the distribution of a data set, showing the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

Front

What are the five parts of the five-number summary?

Back

The five-number summary includes the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

Front

What is the lower quartile?

Back

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

Front

What is the upper quartile?

Back

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

Front

How do you calculate the range of a data set?

Back

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

Front

What is a mode in a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

What is the difference between mean and median?

Back

The mean is the average of all values in a data set, while the median is the middle value when the data is ordered.

Front

What does it mean if a data set is skewed?

Back

A skewed data set is one that is not symmetrical, meaning one tail is longer or fatter than the other.
