Stem and Leaf Plots

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, to retain the original data values while showing their distribution.

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 do you determine the minimum value from a stem and leaf plot?

Back

The minimum value is found by identifying the smallest leaf in the plot, which corresponds to the smallest data value.

Front

How do you calculate the range of a data set from a stem and leaf plot?

Back

The range is calculated by subtracting the minimum value from the maximum value in the data set.

Front

What is the significance of the number of leaves in a stem and leaf plot?

Back

The number of leaves indicates the frequency of data points that fall within the range represented by the corresponding stem.

Front

How can you find the frequency of a specific value in a stem and leaf plot?

Back

To find the frequency of a specific value, locate the corresponding stem and count the number of leaves associated with it.

Front

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

Back

The purpose is to organize and display data in a way that allows for easy visualization of the distribution and identification of patterns.

Front

How do you interpret the data in a stem and leaf plot?

Back

Interpretation involves reading the stems and leaves to understand the distribution, central tendency, and spread of the data.

Front

What is the relationship between a stem and leaf plot and a histogram?

Back

Both are used to display data distributions, but a stem and leaf plot retains the original data values while a histogram groups data into intervals.
