The table below displays the number of copies ordered by several customers at a printing company and the cost of the copy order. Number of Copies 260 325 488 Cost of Copy Order ($) 5.20 6.50 9.76 Is the cost of the copy order proportional to the number of copies? How do you know? No, the relationship is not proportional because the ratio of the cost of the order and the number of copies is not equal to a constant value. This also means that the cost of the order is not a constant multiple of the number of copies .Yes, the relationship is proportional because the ratio of the cost of the order and the number of copies is equal to a constant value. This also means that the cost of the order is a constant multiple of the number of copies . If the relationship is proportional, predict the cost of an order of 600 copies (rounded to the nearest penny). If the relationship is not proportional, type NO SOLUTION in the answer blank. The cost of 600 copies is $
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.
