A Likert scale measures agreement or frequency with a statement using 4-7 ordered options. How to build one that yields reliable data.
A Likert scale asks respondents to rate their agreement with a statement on an ordered set of options—classically five points from strongly disagree to strongly agree. It turns attitudes into numbers you can average, compare and chart, which is why it is the default item type in surveys, evaluations and assessments.
Score = mean of item ratings (1..N); report the mean, the distribution and n.
"I can apply what I learned without extra help." 1 = Strongly disagree … 5 = Strongly agree. A cohort mean of 4.2 with most responses at 4-5 means the training landed.
Use for attitudes, confidence and satisfaction—anything you need to measure as intensity rather than right/wrong. Keep one dimension per scale and word items in the first person.
Don't mix frequency and quality in one scale, and don't average reverse-worded items without flipping their scores first.
Yes for most business surveys: reliable, familiar and easy to report. Use 7 points only when you need finer spread at the extremes.
Strictly it is ordinal, but means and standard deviations are accepted practice with 5+ points and large n—report medians alongside if you want to be safe.
