Consider the scenario.

A scientist sets up an experiment to see how sugar in the diet of
rats affects their weight. The scientist feeds one group of rats a
diet high in sugar, another group a diet of moderate sugar levels,
and a third group a diet low in sugar.

All of the rats in the experiment are the same species and age
and start the experiment at a healthy weight. The rats also
receive the same kind of sugar.

What is the independent variable?

A. amount of sugar
B. weight of the rats
C. age of the rats
D. type of sugar

The dependent variable is affected by the independent one. The amount of sugar (heigh, moderate, low) is the independent variable. Rats weight is the dependent variable.

What are the dependent and independent variables?

Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.

This variable is not affected by any other one but influences or causes a reaction in other variables.

The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.

Its response might be either directly proportional or inversely proportional to the change in the independent variable.

In the exposed example,

Aim of the experiment: to see how sugar in the diet of rats affects their weight.

Independent variable: Amount of sugar (high, moderate, low)
Dependent variable: Rats weight
Control variables: Type of sugar, initial weight

The amount of sugar (independent variable) that was provided to rats will affect or influence their weight (dependent variable).

So, rats weight will change according to the sugar they get in the diet.
