Valide percentage berekenen variabele delen door totale frequentie (minus de missers)
Percentage No Stress: 253/780 = 32.4%
Valide percentage: zonder missing --> 253/770 = 32.9%
Percentage is obtained by dividing the observed frequency by the total NN (including
respondents with a missing value), whereas Valid Percentage is obtained by dividing the
observed frequency by the number of respondents with a valid score (thus, not counting the
persons who had a missing value).
