1. Note any distinctive odor.-Client has slight or no odor of perspiration
2. Inspect for generalized color variations (brownness, yellow, redness, pallor, cyanosis,
jaundice, erythema, vitiligo).-Inspection reveals pale or light ski
The ANOVAF- tests and generalized -test are extended to test hypotheses on the between-study
variance for values greater than zero.
This study uses the ANOVA f test to test hypothesis. It states that the parameter is equal to zero
when using this. It also
Head and Face

1. Inspect head for size, shape, and configuration. Head shape and size vary especially in accord
with ethnicity.
2. Palpate head for consistency while wearing gloves. The head is normally hard and smooth
without lesions.
