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

Front

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.

Front

What does the range of a dataset represent?

Back

The range is the difference between the highest and lowest values in a dataset.

Front

How do you find the upper quartile (Q3) in a dataset?

Back

To find the upper quartile, arrange the data in ascending order and find the median of the upper half of the data.

Front

What is a line plot?

Back

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

Front

What is a frequency table?

Back

A frequency table is a table that displays the number of times each value occurs in a dataset.

Front

How do you create a box plot from a dataset?

Back

1. Order the data. 2. Find the minimum, Q1, median, Q3, and maximum. 3. Draw a box from Q1 to Q3 with a line at the median and whiskers to the min and max.

Front

What is the median of a dataset?

Back

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

Front

What does the whisker in a box plot represent?

Back

The whiskers in a box plot extend from the quartiles to the minimum and maximum values, showing the spread of the data.

Front

How can you determine the mode from a frequency table?

Back

The mode is the value that appears most frequently in the dataset, which can be identified from the highest frequency in the table.

Front

What is the purpose of using a box plot?

Back

Box plots are used to visually summarize the distribution of a dataset, highlighting its central tendency and variability.
