Also how is I do this when my scale has subscales with different values for example one is a 5 point scale strongly disagree to strongly agree and the other is a 3 point scale with never, sometimes and often?
Thank you for your answer. Shall I change the figure in SPSS spreadsheet. Such as, shall I make 3.33 to 3 or shall I leave as it is in newly computed variable. Thanks
Thanks a lot, if i want the combined questions of a likert scale into one new variable, should i use the SUM or MEAN to obtain the new variable, in order to do correlation and regession with it?
The data you combine stems from a Likert Scale, meaning it's ordinal data - should we not calculate the median instead of the mean when combining the items?
Scale are: 1= Strongly disagree and 5= Strongly agree. What shall I do if combine variables is 3.33. Shall I make it as 3 which is undecided. As my values are 1= Strongly disagree, 2= disagree, 3= undecided, 4= agree, 5= strongly agree.
Can you give me reference, please? How did 3 to 3.99 falls to undecided? I'm having a problem on this, i us 4 point likert scale, 1 strongly disagree, 2 is disagree, 3 is agree and 4 is strongly agree. I already got the mean but i dont know where falls where, or to what point does it a number fall.
Hi, what do you do with missing values? Do they have to be coded as missing rather than say -99 and if they are coded as missing are they excluded from the new scale variable automatically?
scale development is usually applicable in the advanced statistical approaches --factor analysis or ANOVA, MANCOVA etc. Instead of using many individual items, you may combine items to develop a scale. Results can be interpreted based on mean score of your scale, say 1 =least to 4 = most. You may see many studies of NSSE that uses scales.

very helpful, thank you

C P same I was thinking this but how would we do that ?
thanks! can I calculate the means for the all the means or sums so I can have just a one value as average..
Could you get the answer for this?
@@asenathbenjamin2520 Yes, and it is possible when you have categorical data.
This is not advisable for Likert scales; when you end up with a value like 4.7, where do you place it? it is not statistically correct

anything from 3 to 3.99 falls within your "undecided category".

Can you please provide the reference to this?
Can I do the median with this data? To get low or high?
Thank u and then how do we interpret that?

Thank you very much! very useful video! keep on going!

I would leave as it is. It does not change the meaning or value because it stands for "neutral"--neither agree or disagree.
