Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

Question

Chapter 3.1, Problem 21E

To determine

To identify: The independent variable and dependent variable.

Expert Solution & Answer

Answer to Problem 21E

The independent variable is number of quarters and dependent variable is amount of time.

Explanation of Solution

Given:

The amount of time fluctuates with number of quarters put in the parking meter.

The dependent variables are those variables that depends on another variable and changes accordingly. It provides output values for the function.

On the other hand, the independent variable is free from the dependency on the another variable and it is the input variable of the function.

In the given problemit can be observed that the amount of time is dependent variable as amount of time depend on the number of quarters that put in the parking meter.

The amount of time increases as number of quarters in parking meter increases and vice versa that means the amount of time is dependent on the number of quarters.

The number of quarters is independent variable as number of quarters does not depend on any other thing. Therefore, it is free to choose.
