For factor analysis data entry in SPSS is not different than you do for other analysis. However, for data reduction through factor analysis, theoretical grounding  of the variables are essential. Do not leave that choice to the software. You will definitely get some tables generated, but may not be very useful.

Dear Helena, Please  let me see your example also!

Thanks Mr. Vasudevan!

Dear Rajat, 

Please see the file attached. I hope you understand portuguese (use google translator). 

But if you have any problem please let me know

Thanks! Uploaded and translated!

Dear Rajat

Factor analysis is an art as well as science. So please see the theoretical settings for the research under consideration. The attachment may be of some use.

Chapter A note on the Factor Analysis in Forestry Sciences

I agree with Bhaswati that the data entry is in the standard format of variables in the columns and cases in the rows.

there have been so many questions about simple factor analysis here that I have recreated a set of resources on that (and another related topic):

 Dear Dr. Roy

Check out the following prior to doing Factor analysis:

We have a set of questions to understand behavioural /attitudinal perceptions in interval scale

Minimum number of samples. though there is no hard and fast rule regarding this, a thumb rule states that the number of samples must at least be five times the number of items (questions) identified to explain the concept

Negative questions are reverse coded, while entering data into SPSS

Do KMO and Bartlett test for spericity (KMO value must be above 0.7 to ensure the sampling adequacy and Sphericity measure (CHi-square)should be statistically significant.

Good luck

Thanks, Sir!!

You can try Minitab. It is user friendly.
