Plot the given data on graph paper to get scatter diagram and then determine regression line of y on x. Graph this regression line on the same scatter diagram. Find the sum of distances from the line to the points. Explain what method of Least squares is. 2481 60.2 Density Compressive 49.9 strength Calculate also, the coefficient of correlation from the data and interpret the results. 2411 2415 2427 2445 2447 2480 50.7 52.5 57.5 58.7 60.1
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.
