Crоnbаch’s аlphа cоefficient and Hоyt’s coefficient are both measures of internal consistency reliability coefficients. Describe how these two coefficients define error variance in their formulas (where reliability = 1 – proportion of observed score variance due to error variance) and how, in spite of those differences, they derive from the same conceptualization of internal consistency reliability.
