Line & Stem-and-Leaf Plots

Front

What is a line plot?

Back

A line plot is a type of graph that displays data along a number line, showing the frequency of each value.

Front

How do you determine the number of data points needed to complete a line plot?

Back

To determine the number of data points needed, subtract the number of recorded data points from the total number of data points expected.

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 retains the original data values.

Front

How do you find the range of a set of data?

Back

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

Front

What information does a stem represent in a stem-and-leaf plot?

Back

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

Front

What information does a leaf represent in a stem-and-leaf plot?

Back

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

Front

How can you interpret the data from a stem-and-leaf plot?

Back

You can interpret the data by reading the stems and leaves to reconstruct the original data values.

Front

What is the purpose of using a line plot?

Back

The purpose of using a line plot is to visually represent the frequency of data points and to easily identify trends or patterns.

Front

How do you identify the number of values above a certain threshold in a stem-and-leaf plot?

Back

Count the leaves that correspond to stems representing values above the threshold.

Front

What is the significance of the median in a data set?

Back

The median is the middle value when the data set is ordered, and it represents the point that divides the data into two equal halves.
