Identify independent and dependent variables

Full solution

Q. The entire high school marching band is going on a field trip. According to school district policy, the number of students on the trip determines how many parent chaperones are required to go along.

\newline

s

= the number of band students on the trip

\newline

p

= the number of parent chaperones required on the trip

\newline

Which of the variables is independent and which is dependent?

\newline

Choices:

\newline

(A)

s

is the independent variable and

p

is the dependent variable

\newline

(B)

p

is the independent variable and

s

is the dependent variable

Question Prompt: The question prompt is: ＂Which of the variables is independent and which is dependent?＂
Determine Relationship: To determine which variable is independent and which is dependent, we need to understand the relationship between the two variables. The independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. The dependent variable is the one that is being tested and measured.
Identify Variables: In this context, the number of band students on the trip $s$ is what determines the number of parent chaperones required $p$ . The policy is likely based on a ratio or a rule that specifies how many chaperones are needed per student. Therefore, the number of students is the variable that influences the number of chaperones, not the other way around.
Variable Analysis: Since the number of students $(s)$ determines the number of parent chaperones $(p)$ , $s$ is the independent variable and $p$ is the dependent variable. This means that the correct choice is (A) $s$ is the independent variable and $p$ is the dependent variable.
