You say please help. That is what we are here for! You just need to tell us what you need help with. It is hard to offer help if we do not know where you are stuck.

I suspect that you failed to read the forum's posting guidelines, so please do that, then post back following those guidelines and you'll receive help.

Read the relevant section(s) of your textbook (or whatever you have) and see what it says about these things. How does it define words like "ratio level", "statistic", "systematic sampling", etc?

This is largely a test of your reading ability more than anything else; we can't do the reading for you, or beat the facts into your head. You won't learn if we just tell you the answers.

Some of these questions, however, take a little thought, and there are legitimate questions you can ask about them. So make some attempt at answering all of them, and give us not only your one-letter answers, but your thinking, so we can help you correct any misunderstandings you have. Ask a specific question, and you'll get a specific answer!
