Document Summary
Observed score is the value obtained directly from a measurement process (e. g. , 38oc) Centred score is the value obtained by subtracting the mean from an observed score (e. g. , 38-37 = 1oc) all add up to 0. Variance is equal to the sum of squares divided by its degrees of freedom s2 = ss = c2 df n-1. Sum of products (sp) is a basic measure of relationship between two variables. Z score a basic form of standard score, calculated as z=c/s (centred score/standard deviation) T-score a transformation of a z score: t = 10z + 50. Deviation score a transformation of a z score: equal to 15z+10. 7: calculate the standard deviation of the following set of 5 scores: 3, 9, 10, 11, 17, max has a systolic blood pressure reading of 128 mmhg and a diastolic blood pressure reading of 78 mmhg.
