Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted on a number line, where each dot represents a data point.

How do you find the mean of a data set?

Back

To find the mean, add all the numbers together and divide by the total number of data points.

What is the median of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there are two middle numbers, add them together and divide by 2.

Front

What is the mode of a data set?

Back

The mode is the number that appears most frequently in a data set.

Front

What is the range of a data set?

Back

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

Front

How do you create a stem-and-leaf plot?

Back

A stem-and-leaf plot is created by separating each data point into a 'stem' (the leading digit or digits) and a 'leaf' (the last digit).

Front

What does a dot plot show?

Back

A dot plot visually displays the frequency of data points in a data set, making it easy to see patterns and trends.

Front

What is the purpose of a stem-and-leaf plot?

Back

A stem-and-leaf plot helps to organize data while preserving the original values, allowing for easy identification of the distribution.

Front

How do you identify the mode in a dot plot?

Back

The mode in a dot plot is identified by finding the value with the most dots above it.

Front

What is the first step in finding the mean?

Back

The first step in finding the mean is to add all the values in the data set together.
