SPSS Database Preparation - Sinhala / SPSS Database හදන හැටි සිංහලෙන් 

Sorry about the sound. This wasn't a structured or preplanned lesson. I just made it as a "kuppi" for about 100 people.

Sorry for the audio quality. This was not a planned session, but a sudden kuppi for a batch of Medical Students 1 day before the deadline. I didn't expect this kind of audience. Hope to conduct a structured session about undergraduate research in future.

Eka nam atta!

Then you have to add yes no fields for each responce, and then multiple responses... See this libguides.library.kent.edu/SPSS/Multiple-Response-Sets

Thanks sir

SPSS is a commercial software. You may request it from your university or workplace.

Shehan, Even with Yes / No type questions there are 3 options neh. 1 Yes 2 No 3 Not marked. Therefore its better to go with my way. You have to use 2 numbers for yes and no. Then Keeping blank is equal to not marked.

Why? We use spss database mainly for analytical purposes. You may keep images in another database.

To get a holistic understanding, each Attitude question was analyzed qualitatively and quantitively. For qualitative analysis we took Likert scale points towards expected positive attitude as ‘Preferred attitude present’ and others as ‘Preferred attitude absent’ and analyzed for frequencies. For quantitative analysis of attitudes we used potential range of scores from -2 to +2, based on the 5-point Likert scale including the following: +2 = Strongly agree to expected positive attitude, +1 = Agree to expected positive attitude, 0 = Neutral, -1 = Disagree to expected positive attitude, -2 = Strongly disagree to expected positive attitude. And calculated the sample mean for each attitude question.

If you're familiar with excel you can generate a function / equation to get "expected positive attitude" or +2 to -2 score easily.

Will see

Change the 'Type' to 'Numeric' then you'll get 'Scale' as a 'Measure'

If you wish to analyse occupation data, its always better to categorize and enter as a code

skewness is a measure of the asymmetry of the probability distribution

If you see question marks on output this means either the user interface language, output or locale language you use, does not fit the language of the files or computer regional settings.

Thank so much
