Dot Plot and Stem and Leaf Review

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

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 the frequency of each 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, where each number is split into a 'stem' (the leading digit) and a 'leaf' (the trailing digit).

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 and a leaf, then list the stems in a vertical column and the leaves in rows next to their corresponding stems.

Front

What does frequency mean in data representation?

Back

Frequency refers to the number of times a particular value or category appears in a data set.

Front

How can you find the total number of items sold from a dot plot?

Back

To find the total number of items sold from a dot plot, add up the frequencies (the number of dots) for all the values.

Front

What is the purpose of a frequency table?

Back

A frequency table organizes data to show how often each value occurs, making it easier to analyze and interpret the data.

Front

How do you determine the number of students with a specific characteristic from a dot plot?

Back

Count the number of dots above the value that represents the characteristic in the dot plot.

Front

What does it mean if a stem-and-leaf plot has more leaves on one stem than another?

Back

It means that more data points fall within the range represented by that stem, indicating a higher frequency for that range.

Front

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

Back

To interpret a stem-and-leaf plot, read the stems to find the range of values and the leaves to see the specific data points within that range.
