## What are three characteristics of the correlation coefficient?

Correlations have three important characterstics. They can tell us about the direction of the relationship, the form (shape) of the relationship, and the degree (strength) of the relationship between two variables.

## What are the key characteristics of correlational research?

Correlational Research is a non-experimental research method. In this research method, there is no manipulation of an independent variable. In correlational research, the researcher studies the relationship between one or more quantitative independent variables and one or more quantitative dependent variables.

## What is considered to be the major characteristic of correlation analysis?

All that correlation shows is that the two variables are associated and nothing more. Any judgment regarding cause and effect must be made based on the investigator’s knowledge and likelihood. Hence, it can be concluded that the major characteristic of correlation analysis is to seek out association among variables.

## What does a correlation indicate?

A correlation is a statistical measurement of the relationship between two variables. A correlation of +1 indicates a perfect positive correlation, meaning that both variables move in the same direction together.

## What is the strength and direction of a correlation coefficient?

This correlation coefficient is a single number that measures both the strength and direction of the linear relationship between two continuous variables. Values can range from -1 to +1. Strength: The greater the absolute value of the correlation coefficient, the stronger the relationship.

## What does R 2 tell you?

R-squared (R2) is a statistical measure that represents the proportion of the variance for a dependent variable that’s explained by an independent variable or variables in a regression model.

## Can coefficient of correlation be greater than 1?

The possible range of values for the correlation coefficient is -1.0 to 1.0. In other words, the values cannot exceed 1.0 or be less than -1.0. A correlation of -1.0 indicates a perfect negative correlation, and a correlation of 1.0 indicates a perfect positive correlation.
