need to be able to tell the difference between a casual relationship and a correlation

A casual relationship is more accurate and a stronger base to prove something whereas correlation can be linked to coincidence

Looking Critically at Data

when deciding how reliable data is you need to consider:

Has the right factor been measured and have the right questions been asked?

how were the data collected? were the methods reliable and the right data used?

Do those collecting the data have a vested interest in the outcome of the research?

Has the study been repeated, with te same results and conclusions by other people?

Are there still unanswered questions?
