The scatterplot below summarizes husbands’ and wives’ heights in a random sample of 170 married couples in Britain, where both partners’ ages are below 65 years. Summary output of the least squares fit for predicting wife’s height from husband’s height is also provided in the table. b) Write the equation of the regression line for predicting wife's height from husband's height and round to 4 decimal places. y =____ + * _____husband's height d) Given that RR = 0.08, what is the value of R2R2 for this data set
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.
