a. To determine To Obtain : The equation of the simple regression relating y to x . Explanation Given info: The researchers wanted to know whether the looks of a person is an advantage for running a political office. A random sample of 641 candidates photos were taken and their beauty ratings was measured on a 5 point scale. The relative success of each candidate is obtained from the percentage of votes obtained was considered as dependent variable and the beauty index is considered as independent variable. Calculation: The equation of the simple regression relating y to x ... b. To determine To Interpret : The y -intercept. c. To determine To Interpret : The slope of the regression line. d. To determine To test : Whether there is any positive relationship between the index and relative success of political candidates at α = 0.01 or not.

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 p…
