An organization that tracks crime statistics reports that cars of make A model U, make A model V, and make B model W are the cars most frequently reported stolen, while cars of make C model X, make D model Y, and make E model Z are stolen least often. Is it reasonable to say that there's a correlation between the type of car a person owns and the risk that it will be stolen? Choose the correct answer below. A. No, since the type of car a person owns is not a quantitative variable. B. No, since there are too few data points to use correlation. O C. Yes, since it is reasonable to find a correlation between any two variables. D. No, because there is clearly no association between the two variables. E. Yes, since there is clearly an association between the two variables.
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 predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
