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.
The following data give the percentage of women working in five companies in the retail and trade industry. The percentage of management jobs held by women in each company is also shown.
a. From the following select the appropriate
b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? POSITIVE LINEAR RELATIONSHIP
c. Try to approximate the relationship between the percentage of the women working in the company and the percetage of the management jobs held by women in that company. Many different straight lines can be drawn to provide a LINEAR approximation of the relationship between X and Y
