ABC Company is exploring different prediction models that can be used to forecast indirect labor costs. On independent variable under consideration is machine hours. Following are matching observations on indire labor costs and machine hours for the past six months: Indirect labor costs P20,000 P24,000 P17,000 P22,000 P13,000 P14,000 Month Machine hours 1 300 2 400 240 370 4 5 200 6 225 Using linear regression analysis, the estimated variable indirect labor cost per machine hour is closest to:
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.
