5. Read the Math Notes box for this lesson, which describes how to find the area and perimeter of a shape. Then examine the rectangle at right, If the perimeter of this shape is 120 cm, which equation below represents this fact? Once you have selected the appropriate equation, solve for . Homework Help 2x + 5 6x – 1 a. 2x+5+6x -1 120 b. 4(6x - 1) = 120 c. 2(6x - 1) +2(2x + 5) = 120 d. (2x + 5)(6x- 1) = 120
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.
