How would you interpret a correlation coefficient of A) 0.84 between two variables? B) -0.02? C) -0.54? What is the coefficient of determination and how do we use it?
correlation coefficient of .84 shows a strong degree of relationship betweent the variable, this show the degree of relation ship between dependent and independt variable means change in 1 point change in independent will cause changes in .84 in depentdent variable
A correlation coefficient of -.02 show the negative but very insignificant degree of association between the variables
A correlation coefficient of -.54 show the strong degree of negative correlation but very significant negative degree of association between the variables
The coefficient of determination is used to measure the proportion of variance of a predicted outcome and it is used to meausre that model is fit to use. it varies With in a range of value of 0 to 1, it is calculated as the square of the correlation coefficient between the sample and predicted data
