Some students believe that if they drink a glass of milk before bed and would make them sleep longer what’s the independent variable dependent variable and a control variables

Answers

Answer:

Independent variable: Glass of milk

Dependent variable: Time of sleep

Control variable: same type of milk

Explanation:

Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.

Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.

A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.

Final answer:

In this milk-drinking sleep experiment, the independent variable is drinking milk at bedtime, the dependent variable's sleep length, and control variables could include other dietary factors, ambient room temperature, bedtime, etc.

Explanation:

In an experimental design, the independent, dependent, and control variables help us isolate cause and effect relationships. In this case, the independent variable would be drinking a glass of milk before bed. This is the variable manipulated or changed in the experiment. The dependent variable is the length of sleep, as it's believed to be influenced by the milk-drinking behavior. Finally, there are multiple potential control variables - factors kept constant to ensure any changes in sleep length are due to the milk intake and not other variables. Such control variables could include the type and volumes of all other consumables, ambient room temperature, time of going to bed, physical activity levels during the day, etc.
