Which Likert Scale Is Best?

What is a good Likert scale?

An effective Likert scale include a series of questions that you ask people to answer, and ideally 5-7 balanced responses people can choose from.

It often comes with a neutral midpoint and essentially measures the level of agreement, so it’s not always numbered scales..

How should Likert scale options be ordered?

When using Likert-type scales, you may list the response options in: ascending order (e.g., Strongly Disagree, Somewhat Disagree, Neutral, Somewhat Agree, Strongly Agree) or. descending order (e.g., Strongly Agree, Somewhat Agree, Neutral, Somewhat Disagree, Strongly Disagree).

Can you average Likert scales?

The mean in a Likert scale can’t be found because you don’t know the “distance” between the data items. In other words, while you can find an average of 1,2, and 3, you can’t find an average of “agree”, “disagree”, and “neutral.”

How do you represent Likert scale data?

The next two charts are probably the most effective ways to display Likert scale data. A stacked bar chart belongs to the part-to-whole group of charts and shows the whole range of evaluation responses, in proportion to one another.

Should you use neutral in a survey?

Research generally shows that including a neutral response will affect the distribution of responses and sometimes lead to different conclusions.

The problem with a Likert scale is that the scale [of very satisfied, quite satisfied, neutral, quite dissatisfied, very dissatisfied, for example] produces ordinal data. … So it would seem that is wrong to calculate means from Likert scales.

What is the 5 point Likert scale?

Definition. A type of psychometric response scale in which responders specify their level of agreement to a statement typically in five points: (1) Strongly disagree; (2) Disagree; (3) Neither agree nor disagree; (4) Agree; (5) Strongly agree.

Is the Likert scale reliable?

Empirical evidence shows that non-Likert scale (0,1,2,3) is 92% reliable while the Likert-type of scale had 90, 89, and 88% reliability. Validity test showed that non-Likert scale was 93% reliable, while the Likert-type scale had 89, 61, and 57% precision.

How many points is a Likert scale?

It’s a question that uses a 5 or 7-point scale, sometimes referred to as a satisfaction scale, that ranges from one extreme attitude to another. Typically, the Likert survey question includes a moderate or neutral option in its scale.

How do you calculate a 5 point Likert scale?

To determine the minimum and the maximum length of the 5-point Likert type scale, the range is calculated by (5 − 1 = 4) then divided by five as it is the greatest value of the scale (4 ÷ 5 = 0.80).

Is Likert scale qualitative or quantitative?

Rating scales do not produce qualitative data, irrespective of what the end-point labels may be. Data from Likert scales and continuous (e.g. 1-10) rating scales are quantitative. These scales assume equal intervals between points.

How do you calculate a 4 point Likert scale?

To interpret a 4 point scale, assign each response a point value, from 1 to 4, based on the number of responses. Common values for the options start with “strongly disagree” at 1 point and “strongly agree” at 4.

How do you know if a Likert scale is reliable?

Reliability can be easily determined with Cronbach’s alpha and intraclass correlations (ICC). You can apply the latter method for test-retest assessment at the item level. Alternatively, applying Pearson’s correlation to the correlation of the summed scale scores also works.

Should we use a 5 or 7 point Likert scale what’s better and why?

7-point scales are slightly better The short answer is that 7-point scales are a little better than 5-points—but not by much. The psychometric literature suggests that having more scale points is better but there is a diminishing return after around 11 points (Nunnally 1978).

When should you use a Likert scale?

It is often used to measure respondents’ attitudes by asking the extent to which they agree or disagree with a particular question or statement. A typical scale might be “Strongly disagree, Disagree, Neutral, Agree, Strongly agree.” Likert scales may meet your needs when you have attitude, belief, or behavior items.

How do you score Likert scale data?

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 read a neutral on a Likert scale?

mean score from 0.01 to 1.00 is (strongly disagree); to 2.00 is (disagree); from 2.01 until 3.00 is (neutral);

Should I use middle position on Likert scale?

You insert a midpoint on the Likert scale to allow respondents to express a neutral opinion between disagreement on one side and agreement on the other. … For a midpoint of neutrality, neutral or neither agree nor disagree are often used.
