Hi,
I have performed analysis of the survey many times and know this topic very well. I can use SPSS, R or just Excel to analyze the data. for your survey. Related to tolls, the data needed for more detail understanding what and how could be received as insights from you data. In general, it can include data inspection (check missing data, unsual data (for example, sometimes people can write 999 are their age and so on). Then, using demographics, the difference between gender, age group, educational levels, occupation and so on can be tested. We can compare average value among demographic groups or proportion (it depends on your data). previously, we should test data for normality distribution. Then. we can use t-test or ANOVA if data have an approximately normal distribution or U-test is data distribution essentially departure from normality. May be regressions are suitable with dummy variables for gender age and so on.
I can't provide examples of my work because system doesn't allow upload any files for bid. But I can provide examples via chat, if you cent message to me.
Also your price 30 USD is very small for this job. My usual price is around 200 USD for survey analysis. I really estimate how much work is needed to conduct accurate and correct survey analysis and find useful insights.
Let me know please if you are interested in my proposal.
Regards,
Alex.
