Odor Measurement How Strong? How Bad? Intensity Offensiveness

Sniff Test #1#2#3#4 How Strong? How Bad?

Sniff Test #1#2#3#4 How Strong? How Bad? Intensity Scale = 0 to 6

Sniff Test #1#2#3#4 How Strong? How Bad? Intensity Scale = 0 to 6 Offensiveness Scale = 0 to 6

Sample 1 How Strong? _____ How Bad? ______

Intensity Scale 0 = no odor 1 = very faint 2 = faint 3 = distinct 4 = strong 5 = very strong 6 = extremely strong

Offensiveness Scale 0 = Inoffensive 1 = Very faintly Offensive 2 = Faintly Offensive 3 = Definitely Offensive 4 = Strongly Offensive 5 = Very Strongly Offensive 6 = Extremely Offensive

Two Assumptions 1.Responses are predictable, but show variability within a population

Two Assumptions 1.Responses are predictable, but show variability within a population 2.Intensity and Offensiveness are independent measurements
