nonnormality, the values between 1.0 and about 2.3 as moderate nonnormality, and the values beyond 2.3 as severe nonnormality” (p. 2). Similarly, Bulmer (1979) pointed skewness, in absolute values, between 0 and .5 shows fairly symmetrical, between .5 and 1 shows moderately skewed and larger than 1 shows highly skewed distribution.
