in this particular scenario, what is the (a) control group and (b) why do we have a control
group?
a student wants to find out which paper airplane flew the farthest. they folded four
different types of airplanes: the basic, the stable, the buzz, the sprinter. student then
measured the distance of the airplane. (choose 2 correct answers - one of the \a\ answers
and one of the \b\ answers.)
a. the stable
a. the buzz
a. the sprinter
a. the basic standard paper airplane
b. we use this group to make comparisons
b. we see what happens when the independent variable is a factor
b. all variables are kept the same in all groups

Explanation:

Question 5

• Control Group (A): In an experiment, the control group is the standard against which comparisons are made. Here, the basic standard paper airplane is likely the control as it serves as a baseline.
• Purpose of Control Group (B): The control group is used to make comparisons. By having a control (the basic airplane), the student can see how the other airplane designs (stable, buzz, sprinter) perform relative to it.

• Quantitative Variables: These are variables that can be measured numerically.
• Weight of your dog: Can be measured in units like pounds or kilograms (numerical).
• Amount of money in your wallet: Can be counted (numerical).
• Non - Quantitative Variables:
• Color of your eyes: Is a categorical (qualitative) variable (e.g., blue, brown).
• Texture of your cat's hair: Is a descriptive (qualitative) variable (e.g., soft, coarse).

Answer:

A. The basic standard paper airplane
B. We use this group to make comparisons
