Please provide a detail explanation. I selected "B", but it was incorrect. On you website, expert stated that it was "A", but it received two dislikes; therefore, I am assuming it was incorrect.

If you want to make a plot that includes change in pulse rate for each drug treatment condition, ________ would go on the x-axis because__________.

o Change in Pulse Rate; it is the dependent variable

o Change in Pulse Rate; it is the independent variable

o Treatment Condition; it is the dependent variable

o Treatment Condition; it is the independent variable

Explanation / Answer

Question: If you want to make a plot that includes change in pulse rate for each drug treatment condition, ________ would go on the x-axis because__________.

Answer: Treatment Condition; it is the independent variable

The independent variables are the variable that can be changed or manipulated and we have control over those variables. The dependent variables are the ones being observed and measured and are affected by other variables. The dependent variables are dependent on independent variables, they change related to a change in the independent variable. To plot a graph using these variables, x-axis is plotted with the independent variable and the dependent variable along the y-axis.

Independent variable would be drug treatment condition, variable that is varied or altered and the dependent variable would be the pulse rate, which is affected by each drug treatment condition (the independent variable). The independent variable always plotted on the x-axis (horizontal axis), and the dependent variable along the y-axis (vertical axis).

The Independent variable : drug treatment condition

The dependent variable: Pulse rate

Therefore, treatment Condition would go on the x-axis because it is the independent variable.
