In this article, you will learn about Stapel Scale.
The Stapel Scale is a one-attribute rating scale used to gauge a person’s feelings toward a specific object or event. It has a range of –5 to +5 and there is no neutral point on the scale (zero).
Its inventor, Jan Stapel, gave the stapel scale its moniker. Scales are typically built vertically, with a single adjective positioned somewhere in the middle of their value range (from -5 to +5). The respondent is asked to select the appropriate numerical response category that best describes the extent to which the adjective associated with the object is accurate or inaccurate. The more positive the respondent’s choice, the more accurately the adjective describes the object.
As an illustration, respondents are asked to rate an airline’s food and crew service on a scale from -5 to +5:
Based on the aforementioned example, the airline is thought to have excellent food, but subpar service from the cabin crew.
Like a semantic differential scale with minor tweaks, the stapel scale is a useful tool. When two bi-polar adjectives can’t be determined, this is a common solution. As with semantic differential data, the resulting interval data is analyzed in the same way.
The stapel scale’s advantage is that it doesn’t necessitate pre-testing adjectives to ensure their true bipolarity. On top of that, it’s simple to administer via phone. Nonetheless, some researchers have a hard time understanding the stapel scale.
