The sales and profit of a clothing organization are represented in the table below. This given data is used in forecasting and mainly decision making, accordingly: Sales , x ( in millions of dollars) Profits, y (in millions of dollars) 1.5 0.1 3.5 0.12 5.4 0.13 6.5 0.17 8 0.21 10 0.27 11 0.25 12 0.24 15 0.28 16 0.30 16.5 0.356 21 0.44 22 0.475 Find the regression equation: use a table to show all your work. Estimate the profit of the organization if the sales reach a net worth of $ 23million. Estimate the sales of the organization if the profit made is $ 1.4million.
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.
