Determine the linear correlation coefficient between Lyme disease and drowning deaths. The linear correlation coefficient between Lyme disease and drowning deaths is r= (C) Does a linear relation exist between the number of reported cases of Lyme disease and the number of drowning deaths? -The variables Lyme disease and drowning deaths are _______associated because r is ___________ and the absolute value of the correlation coefficient, _____ is _____ than the critical value, _____. (Round to three decimal places as needed.)
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.
