Box Plots, Line Plots, & Frequency Tables Oh My!

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, median, third quartile, and maximum.

What does the term 'quartile' mean?

Back

A quartile is a type of quantile that divides a dataset into four equal parts, with each part representing 25% of the data.

How do you find the range of a dataset?

The range is found by subtracting the smallest value in the dataset from the largest value.

Front

What is a line plot?

A line plot is a simple way to display data along a number line, showing the frequency of each value.

What is the median of a dataset?

Back

The median is the middle value when the data is arranged in ascending order. If there is an even number of values, it is the average of the two middle values.

Front

What does the upper quartile represent?

Back

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

Front

How can you determine the number of data points above a certain value in a dot plot?

Back

Count the dots that are located to the right of the specified value on the dot plot.

What is the purpose of a box-and-whisker plot?

Back

A box-and-whisker plot is used to summarize a dataset and show its distribution, highlighting the median and quartiles.
