This helped me so much finding an average scale positive for my applied stats class! Thank you so much for doing these videos!

Yes, well, I just found myself watching your video for the third time because it was so helpful; your explanation addressed an issue that I (as a beginner) haven't dealt with yet. Sorry if I came across as snarky.

Hi, thanks for the video. I am combining many items of likert scale that measures one variable, in order to run regressions. The likert scale is from 1 to 5, strongly disagree to strongly agree. I am confused if I should use mean or sum to combute them? Cuz I thought the likert scale are ordinal data, so mean might not be appropriate. Any advice is highly appreciated. Thanks!

Ah, excellent video. Very good teaching! Thank you!

Thank you! :D This was a great help for computing scores for a quiz I am doing for my undergraduate dissertation.

Hi! Great video! I have a question though, how can i combine the total scores of the subscales to get the total score as a whole and create a new variable?

Hello, thank you for a great tutorial. If I want to compute the total score for each respondent, instead of total mean?

Hi! Thank you for this content this literally helps a lot. Aside from the presentation. How can I correlate a scale with another scale or variable considering that each scale contains a lot of questions?

Thanks for the video! Aside from what you mentioned about missing data in the comments below, is there a reason it is better to use the mean when calculating the score instead of a sum if you are sure there is no missing data?

Thanks a lot for this video.
You have been very helpful!

Hi! great video. It is very helpful but I have some questions.

1. How do I analyse a likert scale data of one variable that have several items? I need to know which items give the most influence to the variable. (note that 1: strongly disagree 2:disagree 3: not sure 4: agree 5: strongly agree)
2. In your opinion, what is the best way to present the data? Is it by percentage, pie chart, mean core, etc?

For example:
What are the reasons for premarital screening? (mark according to scale)
1.1 to find out disease status
1.2 to avoid getting offspring with the disease
1.3 make future planning
1.4 consider to continue relationship

thank you.

Hi. I'm trying to do a correlational study using 3 variables. Data for all three variables were collected using Likert scales. Therefore, I just wanted to know to convert the data from the Likert scale into a variable form so I can run a normality test and correlational test on it? In the video, at the computing part would I have to compute the mean scores of all the items or the median score or the sum?

Hi, thank you so much for been very helpful.

Hi I have a question. How do i measure the Parental Authority Questionnaire using SPSS? I am confused as it does not depend on the total scores but there are subscales: Permissive/authoritarian etc. Please help me out if you can! Thank you.

[katrinajoyescanela]

Hello, thanks for this video, can I use the mean scores as datas for computing ANOVA?

[tombarrows]

Thanks for the video, but it finishes short! After we have calculated the mean scores at the end, what do we do and how do we interpret those results? Thanks

Hi, how do you decide if you should combine items by either using the average or sum and also if a scale was not created to test a variable and you are using two different scales (eg. pay satisfaction and equity sensitivity) . How do you combine items of both scales to create one variable?

[maryembarrit]

so this method is available to give for example the variable of "attitude" a score based on 4 items ? and so to use it for the regression after or the test of KHI2 ?
