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

How do you create a Stem and Leaf Plot?

Back

To create a Stem and Leaf Plot, separate each data point into a 'stem' (the leading digit(s)) and a 'leaf' (the trailing digit). List the stems in a vertical column and write the leaves next to their corresponding stems.

Front

What is the purpose of a Stem and Leaf Plot?

Back

The purpose of a Stem and Leaf Plot is to organize data in a way that allows for easy visualization of the distribution, identification of the median, mode, and range, and retention of the original data.

Front

What is the median in a data set?

Back

The median is the middle value of a data set when it is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.

Front

How do you find the mode in a data set?

Back

The mode is the value that appears most frequently in a data set. A data set may have one mode, more than one mode, or no mode at all.

Front

What does it mean if a class has a higher median?

Back

If a class has a higher median, it indicates that the central tendency of the test scores for that class is higher compared to another class.

Front

What does it mean if a class has a higher mode?

Back

If a class has a higher mode, it means that the most frequently occurring score in that class is greater than that of another class.

Front

How can you compare two Stem and Leaf Plots?

Back

To compare two Stem and Leaf Plots, look at the stems and their corresponding leaves to analyze differences in distribution, median, mode, and overall data spread.

Front

What is the significance of the leaf in a Stem and Leaf Plot?

Back

The leaf in a Stem and Leaf Plot represents the last digit(s) of the data values, allowing for a detailed view of the data while keeping the original values intact.

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, providing a measure of how spread out the values are.
