Answer
Independent
Explanation
## Step 1:In an experiment, the variable that is manipulated or changed by the scientist is referred to as the 'Independent Variable'. This is the variable that the scientist has control over and can alter to observe the effects on the outcome of the experiment.## Step 2:In this particular question, the scientist is changing the type of soil used in the experiment. Therefore, the type of soil is the independent variable in this scenario.## Step 3:The 'Dependent Variable' is the outcome that the scientist measures, which is affected by the changes made to the independent variable. The 'Constant Variables' are those that remain unchanged throughout the experiment to ensure the experiment is fair and that any changes observed in the dependent variable are due to the manipulation of the independent variable only. 'Malaysia' is not a type of variable and is irrelevant to this context.
