a value or criterion that is held to mark the lowest point at which a certain status or category is attained. For example, the cutoff score for passing a course is often 60%. Similarly, the cutoff score for being considered overweight is a body mass index of 25 to 29.
The term cut-off score refers to the lowest possible score on an exam, standardized test, high-stakes test, or other form of assessment that a student must earn to either “pass” or be considered “ proficient .” In some cases, tests may have multiple cut-off scores representing tiered levels of proficiency, such as basic, proficient, or advanced.
A strategy clinical cut offs are often based on is population distribution. For example, moderate could be within one standard deviation of the mean, whereas high is more than one sd above and low is one sd below. In clinical settings, cut-off is often derived from its sensitivity/specificity to differentiate clinical case status.
In clinical settings, cut-off is often derived from its sensitivity/specificity to differentiate clinical case status. As you say, this will probably not be meaningful in your case. You could define a cut-off so that 1/3 of participants fall into each of the three categories though if that makes sense.

What is a cutoff and why is it important?
Cut off is important to ensure compliance with the periodicity concept of accounting. It helps to ensure economic activities and their financial impact is reflected in the same accounting period. So, if an economic activity occurs in one period and is reflected in another period, it leads to cut off error.

How is cut-off point calculated?
A cut-off threshold is used, mainly for cost or burden reasons, to exclude from the target population (hence from the frame) units contributing very little to the requested statistics, small businesses for instance.
How many points should a Likert scale have?
In its final form, the Likert scale is a five (or seven) point scale which is used to allow the individual to express how much they agree or disagree with a particular statement.
How do you calculate cut off points?
Step 1: For each question on the questionnaire, calculate the total number of responses for each sentiment level (Strongly Disagree, Disagree, Neutral, Agree, Strongly Agree). Step 2: Add the totals, and divide by the total number of respondents: 1 + 0 + 0 + 0 + 5 = 6 / 2 respondents = 3.
How do you score a 5 point Likert scale?

How do you analyze a 5 point Likert scale?
The traditional way to report on a Likert scale is to sum the values of each selected option and create a score for each respondent. This score is then used to represent a specific trait — satisfied or dissatisfied, for example — particularly when used for sociological or psychological research.
How do you interpret Likert scale results?
Likert scales typically range from 2 to 10 – with 3, 5, or, 7 being the most common. Further, this progressive structure of the scale is such that each successive Likert item is treated as indicating a ’better’ response than the preceding value.
How do you find the range of a Likert 4 scale?
First method: To determine the minimum and the maximum length of the 5-point Likert type scale, the range is calculated by (5 u2212 1 = 4) then divided by five as it is the greatest value of the scale (4 xf7 5 = 0.80).
How do you interpret Likert scale data analysis?
To properly analyze Likert data, one must understand the measurement scale represented by each. Numbers assigned to Likert-type items express a “greater than” relationship; however, how much greater is not implied. Because of these conditions, Likert-type items fall into the ordinal measurement scale.
