independent variables = amount of compost
dependent variables = number of each type of sprout and average height of sprout
Explanation:
Variables are usually measured and changed during the process of an experiment. They often are classified into two part;
- Independent variables are the ones that are often intentionally manipulated in an experiment. They can be viewed as the cause of phenomenon in an experiment. Here, it is the amount of compost added.
