Named after its founder, psychologist Rensis Likert, the likert scale question is used to understand the degree of consistency that respondents have with a particular statement. The area available in this scale is used to gain knowledge about the feelings and opinions of respondents. Match, frequency, probability, quality or importance can be measured against a Likert scale with appropriate anchors. Scales can be either a unipolar likert scale or a bipolar likert scale. The tempe scale records how much or how well it went. The scale usually has several points that range from “bad” to “excellent” or something in a similar layout. This scale is used for the performance of a product or service, staff skills, customer service performance, processes pursued for a particular purpose, etc. Rating As with star rating, respondents can rate a statement on a visual cardiac scale with the question of cardiac rating. A weight is assigned to each symbol of the heart on the scale. The notions of central tendency are often applicable at the item level – that is, the answers often show an almost normal distribution. The validity of these measures depends on the underlying interval nature of the scale.
If the nature of the interval is assumed for the comparison of two groups, the t-test of t-type samples is not unfit.  If non-parametric tests are to be performed, it is recommended that the pratt (1959)  be modified from the standard wilcoxon signed Rank test.  With the question of the star rating scale, respondents can rate a statement on a visual star rating scale. For example, customers` products receive a rating of 1 to 5 stars to think about their place. The higher the star rating, the better the 4-point Likert scale is actually a forced Likert scale. The reason why it is named as such is that the user is obliged to form an opinion. There is no safe “neutral” option. Ideally, a good scale for market research, they use the 4-point scale to get specific answers. Likert scale questions usually have five, seven, or nine points, with five and seven points more often used.
For example, among the typical multiple choice options strongly agree, agree, disagree, disagree, and strongly contradict in a Likert element. In a Likert poll, adding “something” on both sides leads to sixth and seventh points. The balances are anchored by strong convergence and strong rejection. Some studies suggest that the first page “agree” could inflate scores. . . .
