Dot Plots and Stem & Leaf Plots

Front

What is a dot plot?

Back

A dot plot is a simple way to display data using dots above a number line, where each dot represents one data point.

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, that helps to visualize the shape of a distribution.

Front

How do you read a dot plot?

Back

To read a dot plot, count the number of dots above each value on the number line to determine how many times that value occurs.

Front

What does the 'stem' represent in a stem-and-leaf plot?

Back

The 'stem' represents the leading digit(s) of the data values.

Front

What does the 'leaf' represent in a stem-and-leaf plot?

Back

The 'leaf' represents the trailing digit(s) of the data values.

Front

How can you find the mode using a dot plot?

Back

The mode is the value that appears most frequently, which can be identified by the highest stack of dots in the dot plot.

Front

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

Back

The purpose is to organize data while preserving the original values, making it easy to see the distribution and identify the median and mode.

Front

How do you calculate the range from a dot plot?

Back

The range is calculated by subtracting the smallest value from the largest value in the data set.

Front

What is the median in a data set?

Back

The median is the middle value when the data points are arranged in order.

Front

How do you find the median in a stem-and-leaf plot?

Back

To find the median, list all the values represented by the leaves in order and locate the middle value.
