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…

Textbook Question

Chapter 1.3, Problem 87E

Problems 87 and 88 require a graphing calculator or a computer that can calculate the linear regression line for a given data set.

87. Olympic Games. Find a linear regression model for the men’s 100-meter freestyle data given in the table, where x is years since 1990 and y is winning time (in seconds). Do the same for the women’s 100-meter freestyle data. (Round regression coefficients to three decimal places.) Do these models indicate that the women will eventually catch up with the men?
