The quasi-scientific term "study" is a bit over the top for a data-mining observation that only describes and doesn't make any effort to explain or analyze.

Joe saw Karen pick up her cell phone, so he picked up his cell phone too! Let's publish!

Were this not so, astrology, all description and no explanation, would be classed as a science.
