Question

Read the scenario and answer the questions that follow it in complete sentences. Your answer must include definitions and explanations of the underlined terms.

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep volunteers awake for variable amounts of time. One group of participants was kept awake for 24 hours, and the other was kept awake for 48 hours. During periods of forced wakefulness, participants were required to engage verbal learning tasks such as memorizing the definitions of obscure English words. At the conclusion of the period of forced wakefulness, participants were allowed to sleep for as long as they wanted to. When participants awakened, researchers tested them on the learning tasks they completed during the periods of forced wakefulness. The researchers discovered that participants who were deprived of sleep for 48 hours recalled less than those who had been forced to remain awake for 24 hours.

Requried:
a. What is the independent variable?
b. What is the dependent variable?
c. What is the control group?
d. What is/are the experimental group(s)?

Answer 1

Two different hours of wakefulness is the dependent variable

Verbal learning is the independent variable

Control group : sleeping for long hours

Experimental group are the two categories of people

Step-by-step explanation:

Depends variable is a variable that is varied in an experiment.

The two different length of sleeping hours are the dependent variables,

It cannot stand on its own but rather depend on independent variable.

Independent variable is the variable that can stand on it own. Verbal Learning here is the independent variable and it depended upon by length of sleep.

Control group: Sleeping for long hours, it is the control because that is what nature demand

Experimental group at the people being used for the experiment.
