Carl commented online that they noticed that the greater the number of firefighters at a fire, the greater the damage from the fire. Carl said that this meant that firefighters cause fire damage. Andrea replied to their comment explaining that it is the extent of the fire determines both the number of fire fighters and the amount of damage and that there is no causal relationship between number of firefighters and amount of damage. The relationship that Carl described between number of firefighters and fire damage is an example of a/an _____________ relationship. a. direct b. interactive c. spurious d. intervening
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.
