Concept explainers

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…

Chapter 4, Problem 4.58RE
To determine

To explain why or why not we conclude that preparation causes high scores if we find a correlation of r=0.79 between preparation time and SAT math score.

Expert Solution & Answer
Check Mark

Explanation of Solution

Yes we can conclude that since r is positive as we know that there is a positive association between the variables. Since r is also close to 1 , the association is strong. Thus this means that most time spent preparing will lead to higher SAT test scores.
