Box Plots and Dot Plots

Front

What is a box plot?

Back

A box plot is a graphical representation of a data set that shows the median, quartiles, and potential outliers. It displays the distribution of the data.

Front

What does the median represent in a data set?

Back

The median is the middle value of a data set when it is ordered from least to greatest. It divides the data into two equal halves.

Front

How do you find the mode of a data set?

Back

The mode is the value that appears most frequently in a data set. If no number repeats, the data set has no mode.

Front

What is a dot plot?

Back

A dot plot is a simple graphical display that uses dots to represent the frequency of data points in a data set.

Front

How do you calculate the median of an even set of numbers?

Back

To find the median of an even set of numbers, average the two middle numbers after sorting the data.

Front

What is the range of a data set?

Back

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

Front

What does a box plot indicate about outliers?

Back

In a box plot, outliers are typically represented as individual points that fall outside the whiskers of the box.

Front

How can you identify the quartiles in a box plot?

Back

The box in a box plot represents the interquartile range (IQR), with the left edge being the first quartile (Q1) and the right edge being the third quartile (Q3).

Front

What is the first step in creating a dot plot?

Back

The first step in creating a dot plot is to list the unique values of the data set along a number line.

Front

What is the significance of the whiskers in a box plot?

Back

The whiskers in a box plot extend from the quartiles to the smallest and largest values within 1.5 times the IQR, indicating the spread of the data.
