Question
Use the data to construct a line graph.In a survey, several people were asked how many years it has been since they purchased a mattress. The results are shown in the table below.Years since last purchase (YSP) Frequency0 21 82 133 244 145 9
Solution
To construct a line graph from the given data, follow these steps:
-
Draw a horizontal line (x-axis) and a vertical line (y-axis) on a piece of graph paper.
-
Label the x-axis as "Years since last purchase (YSP)" and the y-axis as "Frequency".
-
Mark the x-axis with the years since last purchase (0, 1, 2, 3, 4, 5). These are your data points on the x-axis.
-
Determine the range of frequencies from the data given (from 1 to 24 in this case) and mark the y-axis accordingly.
-
Plot the data points on the graph. For example, the first data point would be (0,2), the second data point would be (1,8), the third data point would be (2,13), and so on.
-
Connect the data points with a line.
-
Make sure to give your graph a title, such as "Years since last mattress purchase".
Remember, the line graph shows the trend of the data. In this case, it would show how the frequency of mattress purchases changes as the years since the last purchase increase.
