Answer to Question 1
ANS: A, B, C
In an effort to resolve this problem, the visual analog scale was developed to measure magnitude, strength, and intensity of the individual's sensations or feelings. The visual analog, sometimes spelled analogue, scale (VAS) is referred to as magnitude scaling. This technique seems to provide interval-level data, and some researchers argue that it provides ratio-level data. It is particularly useful in scaling stimuli. This scaling technique has been used to measure pain, mood, anxiety, alertness, craving for cigarettes, quality of sleep, attitudes toward environmental conditions, functional abilities, and severity of clinical symptoms. The stimuli must be defined in a way that the subject clearly understands. Only one major cue should appear for each scale. The scale is a line 100 mm in length with right-angle stops at each end. Bipolar anchors are placed beyond each end of the line.
