Reggie computes a correlation coefficient by hand and obtains a value of 4.01. this indicates <u>a computational error. </u> This is because correlation coefficients are supposed to be whole numbers.
A computational error refers to those errors that occur in the computational data such as in matrices or vectors, at the time of computation. Some of the most common computational errors can be copying the question itself as wrong, writing a wrong number, sloppy handwriting, dropping a negative sign, typing wrong in the calculator and not following directions.
One can avoid these computational errors by proper practice of mathematical concepts and reducing blunders.
