The graph shows a student’s data from an investigation about plant growth in five plants of the same type.WeekAvg. Plant Height (cm)Avg. Growth (cm)02NA1312633934145Which is the best way to display this data for analysis?
Answer
A
Place the data in a chart that includes individual measurements before averages were calculated so the information is more complete.
B
Transfer the data into a pie chart with five sections, one for each week, that are sized based on plant growth for that week.
C
Use the first column of data for the x axis the second column for the y axis and plot the data in a line graph to show the growth trend.
D
Use the first column of data for the y axis the second column for the x axis and plot the data in a line graph to show the growth trend.
Explanation
Week is the independent variable, so it belongs on the x-axis. Put the plant measurements from the second column on the y-axis and connect the points in a line graph to show how the measurements change over time. This is the choice that uses the first column for x and the second for y.
