Review 2 research papers that are relevant to your topic. The papers should be research papers not white papers or meta-analysis papers. The papers should be recent (within the last 3 years, unless approved by the instructor ahead of time). 1 paper should use a small sample size and 1 should have a medium to large sample size. If you can find one with a mixed-method approach (if it is relevant to your work, then it can be used as one of the papers). My research topic is The Affects of Physical activity related to social and behavioral development in children
