How do you calculate MCS and PCS?
PCSc was then constructed by multiplying each SF-36 scale z-score by its respective physical factor scoring coefficient and summing the eight products. Similarly, MCSc was created by multiplying each SF-36 scale z-score by its respective mental factor score coefficient and summing the products.
How do you calculate PCS and MCS SF-36?
What is MCS score?
The result is the development of the Meaningful Conversation Score (MCS) – an automatic, unbiased method to measure the relationship between consumers and brands.

All questions are scored on a scale from 0 to 100, with 100 representing the highest level of functioning possible. Aggregate scores are compiled as a percentage of the total points possible, using the RAND scoring table (STEP I chart).
