Question #6c458
1 Answer
a. it is the effect or response
Explanation:
the dependent variable is the variable measured. in an experiment, it is measured in order to find the effect of changing the independent variable on another variable.
the independent variable is manipulated. if it is numerical, it is usually increased or decreased at set intervals, to find its relationship to the dependent variable.
you can control changes in the independent variable, but not in the dependent variable. you do not have control over the effect of changing the independent variable; this must be measured and investigated.
the independent variable is usually graphed on the x-axis, while the dependent variable is usually graphed on the y-axis. this makes it easier to find the relationship between the two, as the gradient of the graph is usually calculated by finding the change in y divided by the change in x.
