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…

For what purpose is the MACRS method used?

A sample of 50 UNR students was randomly selected. A question asked was about annual cost of driving a car and 50 numbers were collected. (Have you ever calculated how much costs you to drive your vehicle annually? The costs should include DMV registration, insurance, gas ( weekly cost times 52), parking, repair and maintenance, tickets/fines, and depreciation. If you have not, find it out. Often, the number is much higher than what you would think.) The sample variance a. should equal to the population variance. b. would change depending on the students included in the sample. c. should be smaller than the sample mean. d. should be smaller than the sample standard deviation.
