There is a weak positive relationship between cholesterol and body mass index. The relationship between body mass and cholesterol level is not negative. Given the correlation between body mass and cholesterol, regression can be used to create an accurate prediction equation. The r-value given for the correlation between body mass and cholesterol level suggestions that using body mass to predict cholesterol leyel may be very
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.
![A medical center would like to be able to predict (estimate) a patient's approximate
cholesterol level by measuring their body mass index. To see if there is a relationship
between cholesterol level and body mass index, a correlation study is performed. The
result of the study suggests that the r-value, or correlation, between cholesterol level
and body mass index is .28. Which statement is FALSE?
There is a weak positive relationship between cholesterol and body mass index.
The relationship between body mass and cholesterol level is not negative.
Given the correlation between body mass and cholesterol, regression can be
used to create an accurate prediction equation.
The r-value given for the correlation between body mass and cholesterol level
suggestions that using body mass to predict cholesterol level may be very
