Well, didn't they have 'Research Methodology' in your University?
Anyways, empirical research is one of the most difficult tasks in legal research. You can start by referring to the published data of the National Crime Records Bureau available online, though I'm not quite sure if they would segregate s*xual offences between workplace and otherwise; that, you'll have to ckeck for yourself.
Next, you should get in touch with HR Departments of major Corporations having their offices in Noida for their statistical data. They'll most likely not be co-operative at all. But if you are able to satisfy them of your good credentials, qualifications, academic affiliations, references etc. they may open up, if only to make a good name for themselves as safe-for-women-wokplace; again, that is something you'd have to work out yourself.
The toughest of the lot would be to have individuals responding to you. I'd suggest dropping a word on Facebook seeking personal feedback from individuals on this subject (and hoping it snowballs); You'd need to establish your credentials, though not as strongly as before a Corporation. It'd be an added advantage if you, or if someone you know, is capable of some web coding to make up a mutliple-options online Poll. Its important to ensure, and convince individuals that you'll ensure, absolute individual confidentiality and the data is being collected strictly for academic purposes.
