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 4.7, Problem 49E

To determine

To use: The equation to predict the number of students assigned to each adviser in the year 2010.

Expert Solution & Answer

Answer to Problem 49E

10 students

Explanation of Solution

Given information: Education: The regression equation for a set of data is y=−3.54x+7125.4, where x represents the year and y represents the average number of students assigned to each advisor in a certain business school.

Calculation:

y=−3.54x+7125.4

y=−3.54(2010)+7125.4→y=10 students
