Hi, this message is in reply to the request from Attaullah Khan copied below.
For a crash course in public health data science, I would try Coursera's Statistical Reasoning for Public Health 1: Estimation, Inference, & Interpretation | Coursera, which can be accessed free if you audit the course (i.e., no tutoring/feedback from instructor, but all other materials provided). This covers the first half of a college level biostatistics course, and can be followed by Statistical Reasoning for Public Health 2: Regression Methods | Coursera - both courses were developed by Johns Hopkins, a trusted research university in the public health field.
As far as free apps go, MS Excel 2003 is free through gmail and has regression and ANOVA capabilities in Windows Livemail I believe:http://people.hws.edu/halfman/excel-demo/linear-regression.html
Many health departments lean heavily on Excel's Pivot Tables feature for internal analysis of data of the kind you are working with:http://www.reading.ac.uk/web/files/www_File_Library/Using_Pivot_Tables_in_Microsoft_Excel_2003.pdf
One advantage to using a program like excel is the options you have for layering data in relational tables: Excel databases: Creating relational tables
Google sheets offers functionalities that are increasingly competitive with Excel's and go beyond Excel in options for geospatial data analytics, but I am not a good source of info on this resource.
Vanderbilt university offers a free app for power calculations you'll need to run before deciding whether your sample size for a given statistical test is adequate: PowerSampleSize < Main < Vanderbilt Biostatistics Wiki
For free apps that cover a wide range of statistical tests relevant to public health, you might try: BioStat 2009 220.127.116.11 Free Download or USMLE Biostatistics - Apps on Google Play
Also, bookmark a good biostatistics glossary like this one: http://www.medicalbiostatistics.com/Glossary.pdf
And use Tableau Public for visualizations: Tableau Public
