Explain how different both means are and explain in which direction the difference is heading. Always make cohen"s d and t score positive. But state whether control or treatment group had a higher score. Linking statements are made to link entire article together. There should be a narrative between each section. They should all link to the big idea. Linking statement made at the end of section b should lead you into whatever you are doing in section: explain what this section has helped you figure out and what you will need to do in next section. One linking statement at beginning and end of each section. Sometimes you can fail to reject when the treatment is actually effective. This can be due to a small sample size. Type i error happens when you mistakenly reject the null hypothesis. Only happens when true cohen"s effect size is 0. Type ii= mistaneleky fail to reject null hypothesis.
