Question

Olivia is conducting a study on whether sleep deprivation increases stress levels. She plans to observe and measure levels of stress based on whether the subjects were assigned to the deprived or non-deprived sleep conditions. In this experiment, the stress level is the:

Answer 1

Answer:

Dependent variable

Explanation:

In research, we have two different types of variables:

• The independent variable is the one that the researchers can control and that will have an effect on another variable.

• The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.

In this example, Olivia is conducting a study on whether sleep deprivation increases stress levels. She is going to observe and MEASURE levels of stress based on the group (deprived or non-deprived sleep) the subjects were assigned to. We can see that the stress will be affected by the conditions of sleep the subjects are assigned to and this is the variable that will be measured. Therefore, the stress level is the dependent variable
