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.

Question

The options are positive, negative, and no correlation. Each of these will have a different answer.

Part 1: Correlation One vital goal of science is to figure out causes. To determine causation is not easy, because we have to be able to distinguish causation from mere association. If two sets of values are related, we call that a correlation in statistical analysis. (If the values of each data source rise together we say they have a positive correlation. If the value of one source rises as the other falls, we call that a negative correlation.) For example you might notice that the more rainfall an area gets, the taller the trees are. The height of trees and the mean rainfall are positively correlated. In this case it is reasonable to suppose that the increased rainfall causes the trees to be taller, but you would have to document that in a controlled experiment. What if you noticed that people with stomach ulcers have a higher incidence of a certain bacterium living in their stomachs? The correlation could be due to the bacterium causing the ulcers, or the ulcers might provide a good…

The amount of an individual consumes daily consumption has no correlation with his/her IQ level. b. It is a positive correlation. The more amount of an individual consumes daily consumption, the lower their IQ level to be. c. It is a negative correlation. The more amount of an individual consumes daily consumption, the lower their IQ level to be. d. It is a negative correlation. The more amount of an individual consumes daily consumption, the higher their IQ level to be. e. It is a positive correlation. The more amount of an individual consumes daily consumption, the higher their IQ level to be.
