The Likert Scale is a popular survey tool that measures attitudes and opinions by asking respondents to indicate their level of agreement or disagreement with a series of statements. The scale is named after its creator, Rensis Likert, an American psychologist who developed it in the 1930s.
At the time, Likert was working at the University of Michigan's Institute for Social Research, where he was involved in studying the attitudes of workers in various industries. He found that existing survey methods were insufficient for measuring attitudes and opinions because they only allowed respondents to choose from a limited set of responses, such as "yes" or "no."
To address this issue, Likert developed a new survey tool that used a series of statements and asked respondents to rate their level of agreement or disagreement on a five-point scale. The scale ranged from "strongly agree" to "strongly disagree," with a neutral midpoint option as well.
Likert's new survey tool quickly gained popularity and was used in a wide range of fields, from education to market research. The scale proved to be versatile and adaptable, and it could be used to measure attitudes, opinions, and beliefs on a variety of topics.
In recent years, the Likert Scale has seen a surge in popularity in business settings, as more and more companies turn to surveys and other forms of feedback to better understand their customers, employees, and other stakeholders.
One reason for the growing use of the Likert Scale in business settings is its simplicity and ease of use. The scale is easy to understand and requires minimal training to administer. This makes it an ideal tool for businesses that want to collect feedback quickly and efficiently, without having to invest in expensive survey tools or consulting services.
Another reason for the growing use of the Likert Scale in business settings is its flexibility. The scale can be adapted to measure attitudes and opinions on a wide range of topics, from customer satisfaction to employee engagement to brand perception. This versatility makes it a valuable tool for businesses that want to gather feedback on multiple aspects of their operations.
Perhaps most importantly, the Likert Scale has proven to be an effective tool for measuring attitudes and opinions in a way that is both reliable and valid. Studies have shown that the scale produces consistent results over time and across different populations, making it a reliable tool for tracking changes in attitudes and opinions. Additionally, the scale has been shown to have strong construct validity, meaning that it measures what it is intended to measure.
While the Likert Scale is a valuable tool for measuring attitudes and opinions, it is not without its limitations.
One of the key limitations is that it only provides a limited range of response options. To overcome this limitation, survey designers often combine Likert Scales with other types of survey questions, such as open-ended questions or multiple-choice questions. This approach allows respondents to provide more detailed and nuanced feedback, and can help to provide a more complete picture of their attitudes and opinions. Additionally, combining Likert Scales with other survey questions can help to minimize response bias, as respondents are less likely to feel limited by the scale and may be more likely to provide honest and accurate feedback. Overall, combining Likert Scales with other survey questions can help to provide a more comprehensive understanding of respondents' attitudes and opinions, and can help businesses to make more informed decisions based on the feedback they receive.
