6 The table shows the number of gallons of gasoline in a car's gas tank after the car has been driven x miles. Gasoline Usage Gallons of Miles Driven, Gasoline in Tank, y 15 10 14.6 20 14.2 35 13.6 60 12.6 75 12 When these data are graphed on a coordinate grid, the points all lie on the same line. What are the slope and y-intercept of this line? F Slope =5, y-intercept = 375 G Slope = 25. Y-intercept = 15 H Slope = 25, y-intercept = 375 J Slope = -25, y-intercept = 15
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.
