Document Summary
Observed score a number that is yielded by a measurement instrument. Mean a benchmark used for judging the place of a score in comparison to other scores among it. Centred score calculated by subtracting the mean from the observed score. Variable a set of scores that differ to a certain extent. Constant a set of scores with no difference. Sum of squares a measure of variation that is calculated by summing the squared centred scores. Covariation measures the relationship between two sets of scores is measured using the sum of products. Sum of products a measurement that is equal to the sum of the products of centred scores. Degrees of freedom the unknown outcomes that you have in a situation. Variance equal to the sum of squares divided by its degrees of freedom. Standard deviation the square root of the variance. Standardized scores centred scores that have been scaled according to standard deviation.
