Understanding Line Plots and Measurements

The video tutorial explains how to record and round data for sleep hours and running times, and how to create line plots to visualize this data. It covers two examples: one for sleep data over four days and another for running times in September. The tutorial demonstrates how to plot data points on a number line and adjust them as needed.

How many days of sleep data are recorded in the example?

• Two days

• Three days

• Five days

• Four days

What is the purpose of rounding sleep hours to the nearest quarter-hour?

• To match the format of the table

• To simplify data entry

• To ensure accuracy

• To make calculations easier

What action is required to add a dot on the line plot?

• Click above the tick mark

• Hover over the tick mark

• Right-click on the tick mark

• Double-click on the tick mark

On which day did the person sleep for eight and a half hours?

• Day four

• Day two

• Day one

• Day three

How many times did Amy run a mile in eight and three-fourths minutes?

• Three times

• Twice

• Once

• Four times

What is the significance of the intervals between eight and nine on the number line?

• They represent half-hour intervals

• They are not used in the plot

• They divide the hour into thirds

• They are quarter-hour intervals

How many times did Amy run a mile in nine and one-fourth minutes?

• Four times

• Three times

• Twice

• Once

What is the total number of times Amy ran a mile in nine minutes?

• Five times

• Six times

• Four times

• Three times

Which of the following is NOT a time Amy recorded for running a mile?

• Nine and a half minutes

• Eight and a half minutes

• Ten minutes

• Eight and three-fourths minutes

What is the first step in creating a line plot for Amy's running times?

• Round each time to the nearest quarter-minute

• Draw the number line

• Identify the longest time

• Count the number of runs
