<span>The coefficient of
determination is presented by R</span>²<span> is mostly used in the analysis of regression
where it is the proportion of the variance in the dependent variable that is
predictable from the independent variable. The range of values between the predicted
scores and the actual scores is between 0 to 1. The closer the value to 1, the
greater is the relationship between variables and has lesser errors. For example,
if there is an R</span>²<span> of 0.80, then it means that 80% is predictable. R</span>² can be obtained using excel as trendline or with the use of formula.
A = 1/2 *2 * h (b1+b2)
a*2 = h (b1+b2) /h
a*2/ h = b1+b2-b1
a*2-b1/ h =b2
