Can parametric statistical tests be used to Analyse questionnaire data?

Because parametric inferences are much easier to interpret and allows for a wider range of analyses, it is not only an option but really a recommendation to use parametric statistics for Likert scales.

How do you Analyse data from a questionnaire in Excel?

The Survey Data Analysis Plan

2. Step 2: Graph Each Question and Add Error Bars.
3. Step 3: Add Histograms of Each Question.

What statistical analysis should I use for Likert scale data?

Inferential statistics For ordinal data (individual Likert-scale questions), use non-parametric tests such as Spearman’s correlation or chi-square test for independence. For interval data (overall Likert scale scores), use parametric tests such as Pearson’s r correlation or t-tests….

How do you Analyse Likert scale results?

A Likert scale is composed of a series of four or more Likert-type items that represent similar questions combined into a single composite score/variable. Likert scale data can be analyzed as interval data, i.e. the mean is the best measure of central tendency. use means and standard deviations to describe the 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)….
