Question

The table shows the average number of hours of exercise each week for different students. Average Time (hours) 3.7 3.3 3.5 3.4 4.0 4.0 3.8 4.0 3.5 3.8 3.8 3.8 Create a line plot to display the data. To create a line plot, hover over each number on the number line. Then click and drag up to plot the data.

Answer 1

To create a line plot to represent this data you will place decimals from 3.3-4.0 on a number line with arrows on each end.  Each decimal should be evenly spaced.  This is what it would look like.

Answer 2

As per the given data table, the dot plot, also known as the line plot is made as shown below.

How does the dot plot work?

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

Thus, suppose if we observed the value 'x', then we will make a dot above 'x'. If there is already a dot over 'x', then we will make a new dot over that dot.

If instead of only observations, the table of unique observation and frequency is given, then we plot dots that many times as the count written in the frequency table. Thus, if its written that the value 2 has 3 has its frequency, then we plot 3 dots one over the other above the value 2 in the horizontal axis.

As per the given data table, the dot plot, also known as the line plot is made as shown below.
