In my survey, 'ICT adoption' as the dependent variable was manifested as use of the respondents of the different forms of ICT--for example., installing wifi or internet service; making the company visible in online booking apps; buying tablets, smartphones or other electronic gadgets for order taking, monitoring and/or reporting; etc. Now, how can I code these options in SPSS?
If I need to create a range--for example, three ICT forms as '1', four ICT forms as '2', etc., does the range need to be similar to the independent variable? For instance, if I used a Likert scale of 5 for the IVs, does the DV also need to have 5 items in the range?
Thanks in advance.
If all your items are all scored 0-1, then you should simply sum them. Trying to collapse those scores (e.g. 1 to 4 = 1) without some theoretical basis will lose information (e.g., what if it should have been 1 to 2 = 1 but you guessed wrong).
The one exception might be if the scores at the high end of the scale are strongly skewed, in which case you might collapse the top range into a single "highest" score.
To be honest without looking at your data set it’s difficult for me to comment. I suggest you use SPSS and run a factor analysis for all your questions. Then you will have an idea about the response you have got and how they are grouped.
Also see if your data is normally distributed or not. If it’s normal distributed, then you can try parametric tests. If not you have to go for non parametric tests
