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
