Quantitative Research | Likert Scale: Should I Use Parametric or Non-parametric Tests?

A passionate dispute over the use of parametric versus non-parametric methods for the analysis of Likert scale data has raged for the past eighty years. The answer is not a simple “yes” or “no” but is related to hypotheses, objectives, risks, and paradigms. In this video, I will be presenting to you the arguments of the two sides of this dispute: the ordinalist which believe that Likert Scale data should be analyzed by nonparametric tests, and intervalist which believe the other way around.

I have come across debates whether "NEUTRAL" in a five point scale should not be included in the analysis as it doesn't represents any position. I am wondering how his could be taken care of.

Hello sir, I need help for my college thesis. I am using Likert scale 1-Strongly Disagree, 2- Disagree 3- Agree, 4-Strongly Agree. Now my instructor wants to find computed x squared and p value through Pearson's r to either reject or accept my null hypothesis. One of my SOP is finding the significance between profile (gender, age, course and year) and thr factors pertaining to the perspective of graphic designers (which each section contains about 7-8 questions). How can I do Pearson's r with these?

Hi, thanks for your video. I have survey results expressed in likert scale (1, 2, 3, 4, 5). Some of the questions are about input variables while the other are related to the dependent one that is the object of the study. If I would use Orange software should I apply a linear regression, a random forest or another kind predictive model node ? Thank you

[jamailuk]

You make a very solid and informed argument. Thanks for settling the case for me, am now able to revise my report based on this. Many thanks.

How about I use likert scale with a objectives of the levels of intrinsic and extrinsic Motivation what can be the analysis and scoring? What is arbitrary scale?

[mariannerosehernandez]

Hello, I've come across this video of yours, can you suggest the best way in finding out the results with this SOP of mine?
SOP 1 – Finding out the demographics of the students pertaining to their sex.
SOP 2 – Identifying the final ratings of 2nd year nursing students in all of their NCM lab subjects pertaining to return demonstration activities.
SOP 3 – Is there a significant relationship between the academic laboratory performance of nursing students with their demographics?
SOP 4 – To carry out the Output and Recommendations after conducting the study.

THANK YOU!

interesting. my first time to hear about ordinalists vs intervalists on likert data. my orientation has always been to approach it as ordinal. btw, are you a statistician by profession?

[silenciozoe]

hi sir, I have a study which has a likert scale type of questionnaire and I'm using the data for Multiple Regression Analysis in order to check whether my independent variables have a significant influence on my dependent variable. My research title is about Factors influencing Purchase Intention and I've seen a lot of related studies that uses likert scale data which is then analyzed via Multiple regression. I hope you can help me with this problem... How can I use the likert scale data for multiple regression analysis?

[shahzadnawaz]

my questionnaire is on likert scale data which is ordinal data but my study type is quantitative .. can ia use nonparametric test ??

i have collected data for both dependent and independent variable on 5 point likert scale like strongly agree, agree, neutral, disagree and strongly dis agree. sir which test should i perform

[alvintanap]

Sir What statistical tool or treatment of data should you use in determining the
number of respondents who said “yes” or “no” to as particular question as
well as the percentage?

[anthonygikuri]

Thank you for your video. It's useful. Could you provide me with the full references among the proponents who regard likert scale as interval or approximate ratio..

[chanexpatriciosongcovers]

Sir what about you have 5 scale but 10 questions?

[tbdfuu-ffjt]

An accurate description of likert scale and its analysis. Thanks.👍

[kylecarlodz]

Hi sir. I created a 5 point- Likert Scale. I need to find a range po of the Likert Scale. Using this formula Highest Score for response- Lowest score for response divided by number of response.
(5-1)= 4
4÷5= 0.8 is the range of the Likert Scale po.
0.80- 1.80 Not Aware at All
1.81-.2.80 Slightly Aware
2.81- 3.80 Moderately Aware
3.81-4.80 Very Aware
4.81-5.00 Extremely Aware
Is this correct Sir in getting the range of the scales?

I saw another study sir. He also has a 5 point Likert Scale but instead of 0.80, it has ait started in 0.50. Like this:
0.50- 1.50 Not Aware at All
1.51- 2.50 Slightly Aware
and so on.
What formula did he possibly use? Hoping you can answer this question thank you.

Good day po, sana mapansin niyo po itong comment ko..
ano po ang dapat gamitin namin sa statistical treatment po?
SOP po namin ( suggest po ng prof namin ito)
1. How may the respondents describe in terms of:
1.1 SEx
1.2 Year level, and
1.3. Strand?

2. What are the factors that affect the students' performance online class?
3. Is there a significant difference on the factors affecting the academic performance of the students in online class when they are grouped according to profile?

Our title po is " Factor affecting senior high school students' academic performance during online class"

Hypothesis po namin is - Null

Sana po mapansin. salamat po.

Hello sir. Do u accept emailed queries?

@raffycee sir I'm using 3 Likert scales ( 1 for independent variable other two for dependent variable). my objective is to find a relationship between them. can I go with mean, sd, and correlation?
