@Norwegian Research Training Institute Dear sir, Is there perhaps a reference (from an academic article) that supports the following statements: 1. a) The mean can be used to calculate the scale scores for ordinal data (with 5 type likert items). b) And if the data is not normally distributed you can still continue the use of the mean scalescores. 2. And if the data is not normally distributed you can apply/ use the ordinal logistic regression method instead of the multiple regression analysis. 3. And the interpretation of the parameter estimates of ordinal logistic regression is in this case almost the same as multiple regression where the main aspects are: the beta coefficients, the significance/p-value en the R square/nagelkerke pseudo R. Kind regards, Elizabeth
@@norwegianresearchtraininginsti okay.... But why should the mean still be applied to the scale scores if the data is not normally distributed? Shouldn't the median be used instead?

Thank you for this clear explanation. I am writing on the effect of management style on employee performance in a post-global pandemic world. can I have my dependent variables "employee performance" and independent variable "management styles" now my question is, how do I test the management style that will be best for remote workers, and secondly, I have some dichotomous variables, how do I transform them? thank you
Hello, hope you are well? first, I just want to say that I am so grateful for this video, indeed it is quite comprehensive, but please i am presently working on my project and as i follow your step i was stuck on the ordinal regression session. For some reason after inputting my dependent, factor and my covariant variables, i then click on "scale" to input my covariant but it's not allowing me to select as you have done on the tutorial, making my results show without a scale description. Please it will be much appreciated if you can give me some insight on how to do this Kind regards
If all my independent variables are likert scale or dummies, would it still be possible to run multiple linear regression with a dependent Likert 5 scale? Thanks for the video!
9 months later, I am stuck exactly here. Please help if you came right. I have all 5 independent Likert scale variables, I don't know which regression to run
I have never had that being used for transforming non-normal. However, there are emerging new discoveries in this area: I know use of logarithm, square and cuberoot, inverse and introducing a constant as explained in SPSS survival manual by Julie Pallat
In my case, I want to find the T test between the gender and five factors. I want to put the data in my table consists gender and the whole result T test for the factors not for each factors. Can you understand what I'm talking about? If you do, please help me!
Thank you Peter. Please I have a data set collected with the use of likert scale. Following your example I run a normalily test and my independent variables(2) were not significant(above 0.05) but the dependent variable was significant. Please can I still go ahead and use the Ordinal logistic regression method th analyse my data?
There are many normality tests that you can use or apply to know whether your data is normally distributed or not. For example Shapiro & wilk test , D' Agostino test etc.
Normality should be tested for dependent variable since independent can be continuous or categorical. Though categorical is best fit if we convert them as dummy before fitting in OLS model
I have a question. I have a Likert scale question (a SINGLE question) that measures a construct. Is this usable? Can I still do tests and do I still need to compute variable?? I can't find the answer anywhere and I feel like I've done it wrong :(
What does the literature say? Look in the literature to see if anyone else has used a single item of measurement for your construct. If so, cite it and proceed with your test based upon your research design and level of measurement of your variables. Google (single item measure of “construct’s name” ). Hope this helps
how on earth can this entry be used for T-test. i entered my data just the way you did and now I am finding it so herculean to test two means.... the groups are tow many to test with a mean. i just wish you understand
In data normality test, can we neglect or delete those variables or operationalized questions that are not normal? In order to go for peramatric test instead of non-parametric test throughout analyzing the data.
Would it be meaningful to use the mean as a measure of central tendency to a 4 point likert scale data? Or would it be better to measure the data in frequency? Thank you.

run Wilcoxon signed-rank test if normality fails but if the variables has normal distribution then run paired sample t-tests

Proceed since Normality is not required for ordinal regression
Hy
Plz understand the outlier and also tell what is range of Normality .how we are confident that our data is normal distributed
There are many normality tests that you can use or apply to know whether your data is normally distributed or not. For example Shapiro & wilk test , D' Agostino test etc.
Can we use likert scale without a hypothesis in the study.
why not,
Sir, how do you compute the values for the dependent variable in SPSS. I can't perform regression as my dependent variable cases are not defined 😢😢
@@MERVINBANDA-z8y use transform menu in spss
I have 3 Likert scale of 5 points and 1Likert scale of 4 points. I read below we can run a multiple linear regression with 4 points. Any suggestion?
Please explain how to deal if there is an outlier
u do data lean up replace all outliers with mean value, or medium or mode value in your dataset
thanks you peter
Why we must test normality for independent variable instead residual variable for Regression Assumptions ?
Normality should be tested for dependent variable since independent can be continuous or categorical. Though categorical is best fit if we convert them as dummy before fitting in OLS model
How did you pick the dependent variable from the questions
Dependent variable was performance which had ten questions so I got their mean value .
this is a research that was done and the questionnaire had 10 likert -scale questions on dependent variable. so
I have a question. I have a Likert scale question (a SINGLE question) that measures a construct. Is this usable? Can I still do tests and do I still need to compute variable?? I can't find the answer anywhere and I feel like I've done it wrong :(

Can you please answer this question?
Introduction of this course check here ruclips.net/video/5RfR4aJd6qM/видео.html
If your sample is more than 30, dou you have to normalize?
In data normality test, can we neglect or delete those variables or operationalized questions that are not normal? In order to go for peramatric test instead of non-parametric test throughout analyzing the data.
deleting is only option for dealing with outlier , normality you transform the variable and work subsequenlty with transformed data for normality
Would it be meaningful to use the mean as a measure of central tendency to a 4 point likert scale data? Or would it be better to measure the data in frequency?
Thank you.
Not meaningful just use frequencies likert scale remain categorical variable
