What is a Stem-and-Leaf Plot?

Back

A Stem-and-Leaf Plot is a method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values while showing their distribution.

Front

What is a Box-and-Whisker Plot?

Back

A Box-and-Whisker Plot is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

What does IQR stand for?

Back

IQR stands for Interquartile Range, which is the difference between the first quartile (Q1) and the third quartile (Q3) in a data set.

Front

How do you calculate the Median?

Back

To calculate the Median, arrange the data in ascending order and find the middle value. If there is an even number of observations, the median is the average of the two middle values.

Front

What is the Mode of a data set?

Back

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

Front

What is the purpose of a Box-and-Whisker Plot?

Back

The purpose of a Box-and-Whisker Plot is to visually summarize the distribution of a data set, highlighting its central tendency and variability.

Front

What does the top 25% of data represent in a Box-and-Whisker Plot?

Back

The top 25% of data represents the values above the third quartile (Q3) in a Box-and-Whisker Plot.

Front

How do you find the range of a data set?

Back

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

Front

What is a Quartile?

Back

A Quartile is a type of quantile that divides a ranked data set into four equal parts, with each part containing 25% of the data.

Front

What does the Whisker represent in a Box-and-Whisker Plot?

Back

The Whiskers in a Box-and-Whisker Plot extend from the quartiles to the minimum and maximum values, showing the spread of the data.
