Explanation Given: Consider the following statement about a correlation. In this case, state the correlation clearly (for example, there is a positive correlation between variable A and variable B ). Then state whether the correlation is most likely due to coincidence, a common underlying cause, or a direct cause. Explain your answer. “Over a period of twenty years, the number of ministers and priests in a city increased, as did attendance to movies.” The correlation for the given statement: “Over a period of twenty years, the number of ministers and priests in a city increased, as did attendance to movies”. The number of ministers and priests in a city and attendance to movies are directly not correlated...

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…
