Unit 10 Assessment - Line Plots and Stem-and-Leaf Plots

Front

What is rounding?

Back

Rounding is the process of adjusting a number to make it simpler while keeping its value close to what it was. For example, rounding 72.495 to the nearest whole number gives 72.

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line. Each mark above a number represents one occurrence of that number.

Front

How do you find the total number of students in a line plot?

Back

To find the total number of students in a line plot, count the marks above each number and add them together.

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a way to display data where each number is split into a 'stem' (the leading digit or digits) and a 'leaf' (the last digit).

Front

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

Back

To read a stem-and-leaf plot, look at the stems on the left and the leaves on the right. Each leaf represents a value that combines with its stem.

Front

What does it mean for a number to occur most often in a data set?

Back

The number that occurs most often in a data set is called the mode. It is the value that appears with the highest frequency.

Front

How do you determine the mode from a line plot?

Back

To determine the mode from a line plot, look for the number with the most marks above it. That number is the mode.

Front

What is the purpose of using a line plot?

Back

The purpose of using a line plot is to visually display data and make it easier to see patterns, trends, and frequencies.

Front

What is the difference between a line plot and a stem-and-leaf plot?

Back

A line plot shows data points along a number line, while a stem-and-leaf plot organizes data into stems and leaves to show the distribution of values.

Front

How do you create a stem-and-leaf plot from a list of numbers?

Back

To create a stem-and-leaf plot, separate each number into a stem and a leaf, then list the stems in a column and the corresponding leaves next to them.
