When a group or organization needs to conduct research, they can use the effectiveness of a well-organized questionnaire or scale but simple. This simple approach will help answer many of the questions the group or organization seeks to explore. Although I mentioned a simple questionnaire, implementing one of these questionnaires or scales involves using different techniques and approaches to effectively interpret each response. The following sample scales are just a few of the many ways a group or organization can conduct its market research. These examples are the Likert scale, the semantic differential scale and the Stapel scale. I will first talk about the Likert scale. The Likert scale is a very popular type of questionnaire used in the educational world. It was developed by Rensis Likert, who was an educator and psychologist. Since the inception of this scale, there have been many different versions based on the number of points on the scale. The Likert scale can be four, five, six points, etc. The even number scale primarily prompts the respondent to choose, while the odd number scale offers the option of indecision or neutrality. Indecision or neutrality can make this type of questionnaire less effective in trying to find a definitive answer to your research. The second type of questionnaire or scale is the semantic differential scale. This type of questionnaire was developed by Charles Osgood in 1957 and is used to measure the meaning of concepts, opinions and attitudes. This type of scale is a little unusual because it is made up of paired words which are most of the time their opposites. As it is considered somewhat unusual, this type of scale s...... middle of paper ......l, and it can be used as an alternative to the semantic differential scale. In conclusion from my research, if I had to choose between a questionnaire type or a scale, I would probably choose to use the Stapel scale. From what I observed during my research, I noticed that most marketing studies carried out do not use this type of questionnaire. The reason the researchers didn't choose this type is that the instructions and formatting seem too complex. I think because of its ability to analyze data much like the Semantic Differential Scale and calculate overall attitude scores by adding up the scores on individual items, it intrigues me more. Having personally completed all of these types of questionnaires throughout my life, I have always found the Stapel scale to be more effective in providing me with a more accurate response to research..
