Box and Whisker, Stem and Leaf Plots - Flashcard

Front

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 'whisker' in a Box Plot represent?

Back

The 'whisker' in a Box Plot represents the range of the data outside the interquartile range, extending to the minimum and maximum values.

Front

What is the purpose of a Stem-and-Leaf Plot?

Back

A Stem-and-Leaf Plot is used to display quantitative data in a way that retains the original data values while showing the shape of the distribution.

Front

How do you find the median in a Box Plot?

Back

The median is represented by the line inside the box of a Box Plot, dividing the data into two equal halves.

Front

What do points A and E represent on the Box Plot?

Back

Points A and E represent the least and greatest values in the dataset.

Front

What is the interquartile range (IQR)?

Back

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

Front

How do you calculate the average (mean) of a dataset?

Back

To calculate the average (mean), sum all the data values and divide by the number of values.

Front

What is a quartile?

Back

A quartile is a type of quantile that divides a dataset into four equal parts, with Q1 being the first quartile, Q2 the median, and Q3 the third quartile.

Front

What does the upper quartile (Q3) represent?

Back

The upper quartile (Q3) represents the value below which 75% of the data falls.

Front

What is the lower quartile (Q1)?

Back

The lower quartile (Q1) is the value below which 25% of the data falls.
