Nalah labels ten rats with the numbers 1 through 10. Then, she records how long it takes each rat to run through a maze. She finds it difficult to graph her data in a line graph. What change could she make to her experimental design that would allow her to plot a clearly displayed data trend in a single line graph? A) Repeat the experiment ten times. Label the y-axis “Time” and the x-axis “Trial.” Plot the average time for all ten rats for each trial of the experiment.
B) Divide the rats into groups of females and males and repeat. Label the y-axis “Time” and the x-axis “Sex of Rat.” Plot the average time for each group.
C) Repeat the experiment ten times. Label the y-axis “Rat Number” and the x-axis “Time.” Plot the individual time for all ten rats for each trial of the experiment.
D) Divide the rats into two groups based on their speed from the initial data. Label the y-axis “Time” and the x-axis “Group.” Plot the average time for each group.
