A Likert scale is considered a quantitative measurement tool because it assigns numerical values to responses and allows for numerical analysis of data.
To create a Likert scale questionnaire, first define the statements or questions to be rated. Then, choose a scale, such as a 5-point scale ranging from "Strongly Disagree" to "Strongly Agree." Next, present the statements along with the scale and ask respondents to select the option that best represents their opinion. Finally, analyze the responses by calculating averages or percentages for each statement.
