Independent variables cause an effect on the dependent variables. In the exposed example,<em> the</em><em> dependent variable</em><em> is the </em><u><em>loss of soil</em></u><em> (g), </em>which is affected or influenced by the other variables. Option 3.
<h3>
What are de dependent and independent variables?</h3>
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.
Now let us answer the question.
In the exposed example, there are four possible variables.
- soil type
- degree of slope
- loss of soil (g)
- air temperature
The only one that can be affected by the other variables is the <u>loss of soil.</u>
The degree of soil loss can be affected by the type of soil, the degree of slope, and environmental temperature.
The correct option is 3. Loss of soil (g)
