Question

the first study measured the abundance of parasites in the blood of one human patient during the first few weeks of a chronic infection. the results are shown in the table. you decide to plot the data as a line graph. day number of parasites (in millions) per ml of blood 4 0.1 6 0.3 8 1.2 10 0.2 12 0.2 14 0.9 16 0.6 18 0.1 20 0.7 22 1.2 24 0.2 which column represents the independent variable, and which axis should it be plotted on?

Answer 1

The independent variable in this study is the day number, and it should be plotted on the x-axis. The dependent variable is the number of parasites per ml of blood and should be plotted on the y-axis.

Step-by-step explanation:

The independent variable in this study is the day number, as it represents the different time points at which the abundance of parasites in the blood was measured. The dependent variable is the number of parasites (in millions) per ml of blood, as it is the variable that is being measured and affected by the independent variable.

To plot this data as a line graph, you would plot the day number on the x-axis (horizontal axis) and the number of parasites (in millions) per ml of blood on the y-axis (vertical axis). This will show the changes in parasite abundance over time.
