1.
In an experiment, what is the measurable variable, also known as the dependent variable (DV)?
Correct Answer
C. The variable measured in the experiment, dependent on changes to the independent variable (IV).
Explanation
The measurable variable, or dependent variable (DV), is the one that is measured in an experiment. It depends on changes made to the independent variable (IV). The experiment aims to study the effects on the DV resulting from variations in the IV, making option C the correct answer.
2.
The independent variable (IV) changes the dependent variable (DV).
Correct Answer
A. True
Explanation
The statement is true because the independent variable is the variable that is manipulated or changed in an experiment, and it is expected to have an effect on the dependent variable. The dependent variable, on the other hand, is the variable that is measured or observed and is expected to be influenced by the changes in the independent variable. Therefore, it is correct to say that the independent variable changes the dependent variable.

The deeper I cut, the more it will bleed.
The 2 variables:
1. Depth of cut
2. Level of bleeding
Which is the independent variable?
Correct Answer
B. Depth of cut
Explanation
The independent variable in this scenario is the depth of cut. This means that the level of bleeding is dependent on the depth of the cut. As the depth of the cut increases, the level of bleeding also increases. The depth of the cut is the factor that is being manipulated or changed in order to observe the effect it has on the level of bleeding.
4.
If I add more milk, the tea will get a lighter color.
The two variables:
1. Amount of milk
2. Color of the tea
Which one is the independent variable?
Correct Answer
A. Amount of milk
Explanation
The independent variable in this scenario is the amount of milk. This is because the amount of milk is being manipulated or changed by the person making the tea. The color of the tea, on the other hand, is the dependent variable as it is influenced by the amount of milk added. As more milk is added, the tea gets a lighter color.
5.
I need to pay a fine because I crossed the red light.
The 2 variables:
1. Paying fine
2. Crossing red light
Which is the independent variable?
Correct Answer
A. Crossing red light
Explanation
The independent variable in this scenario is "Crossing red light". This is because it is the factor that is being manipulated or changed by the individual's actions. The act of crossing the red light is what leads to the need to pay a fine. The variable "Paying fine" is the dependent variable, as it is the outcome or result of crossing the red light.
6.
Add extra sugar to make it sweeter.
Which of these is the dependent variable in this?
Correct Answer
B. Level of sweetness
Explanation
The dependent variable in this scenario is the level of sweetness. The amount of sugar added is the independent variable, meaning it is manipulated to determine its effect on the level of sweetness. The level of sweetness is the variable that is being measured or observed, and it is dependent on the amount of sugar added. Therefore, the correct answer is "Level of sweetness."
7.
I will feel lazy if I eat too much.
The 2 variables:
1. Amount of food eaten.
2. Level of laziness
Which one is the dependent variable?
Correct Answer
B. Level of laziness
Explanation
The dependent variable in this scenario is the level of laziness. This means that the level of laziness is influenced or determined by the amount of food eaten. In other words, the amount of food eaten is causing or affecting the level of laziness.
8.
I will lose extra fat If I run extra hours.
The 2 variables:
1. Amount of fat lost
2. Hours of running
Which is the dependent variable?
Correct Answer
A. Amount of fat lost
Explanation
The dependent variable in this scenario is the amount of fat lost. This means that the amount of fat lost is influenced by the hours of running. The more hours of running, the more fat is likely to be lost. Therefore, the amount of fat lost is dependent on the hours of running, making it the dependent variable in this case.
9.
It will get colder if winds blow faster.
The 2 variables:
1. Wind's speed
2. Amount of cold
Which is the dependent variable?
Correct Answer
B. Amount of cold
Explanation
The dependent variable is the one that depends on or is affected by changes in the other variable. In this case, the amount of cold (i.e., how cold it gets) depends on the wind's speed. Therefore, the amount of cold is the dependent variable in this statement. As the wind's speed changes, it influences how cold it becomes.
10.
Does working extra hours in the office get you more recognition?
The 2 variables
1. Number of hours
2. Level of recognition
Which is the dependent variable?
Correct Answer
A. Level of recognition
Explanation
The dependent variable in this scenario is the level of recognition. This means that the level of recognition is influenced or affected by the number of hours worked in the office. The more hours a person works, the higher their level of recognition may be.
