Blood pressure measurements consist of two numbers, the systolic pressure and the diastolic pressure. Subjects taking an experimental blood pressure medicine had the following measurements: Systolic 134 115 113 123 119 118 Diastolic 63 83 77 77 69 75 Compute the correlation coefficient. Round your answer to three decimal places. Write only a number as your answer.
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.
