Question

independent variable mean

Answer 1

In statistics and research, an independent variable is a variable that is manipulated or controlled in an experiment to test its effects on a dependent variable. The independent variable is often considered the "cause" in a cause-and-effect relationship.

For example, in a study examining how different amounts of sunlight affect plant growth, the amount of sunlight would be the independent variable, while the growth of the plants (measured in height, weight, etc.) would be the dependent variable. The independent variable is systematically varied to observe how changes influence the dependent variable.

It's important to note that the term "mean" usually refers to the average value of a set of numbers, which is a different concept. If you're referring to the mean of the independent variable in a dataset, it would simply be the average of its values. For instance, if you've measured sunlight exposure in hours per day over several days, the mean would be the total hours divided by the number of days measured.
