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 the distribution.

Front

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

Back

In a stem-and-leaf plot, the 'stem' represents the leading digit(s) of the data points, while the 'leaf' represents the trailing digit. For example, in the stem '5 | 3', '5' is the stem and '3' is the leaf, representing the number 53.

What is the purpose of using a dot plot?

Back

Dot plots are used to display small sets of data and to show the distribution of data points clearly.

Front

How do you determine the number of data points in a stem-and-leaf plot?

Back

Count the total number of leaves in the plot; each leaf represents one data point.

Front

What type of data is best represented by a stem-and-leaf plot?

Back

Stem-and-leaf plots are best for small to moderate-sized datasets of quantitative data.

Front

What is the advantage of using a stem-and-leaf plot over a histogram?

Back

A stem-and-leaf plot retains the original data values while providing a visual representation, unlike a histogram which groups data into bins.

Front

How can you identify the mode in a dot plot?

Back

The mode in a dot plot is the value that appears most frequently, represented by the highest stack of dots.

Front

How do you create a dot plot?

Back

To create a dot plot, draw a number line and place a dot above the number for each occurrence of that number in the dataset.
