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…

Textbook Question

Chapter 1.2, Problem 5A

Sometimes bar graphs will have more than one bar in each category. This is useful when categories can be divided into subcategories. An example of this is shown in the graph below, which was reproduced from the website of the Substance Abuse and Mental Health Services Administration, a division of the U.S. Department of Health and Human Services. A study was done on alcohol use among people in the 12-20 age bracket in 2010, with some results summarized by the graph. The SAMHSA website defines alcohol use as follows:

Current (past month) use - At least one drink in the past 30 days.

Binge use - Five or more drinks on the same occasion (i.e., at the same time or within a couple of hours of each other) on at least 1 day in the past 30 days.

Heavy use - Five or more drinks on the same occasion on each of 5 or more days in the past 30 days.
