A sports statistician was interested in the relationship between game attendance (in thousands) and the nu wins for baseball teams. Information was collected on several teams and was used to obtain the regression equation ý = 4.9x + 15.2, where x represents the attendance (in thousands) and ý is the predicted number Which statement best describes the meaning of the y-intercept of the regression line? O When the number of wins is 0, the predicted attendance is 0. O When the number of wins is 0, the predicted attendance is 15,200. O When the attendance is 0, the predicted number of wins is 4.9 O When the attendance is 0, the predicted number of wins is 15.2.
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.
