Many grops take a half day near the start, to go to the library and design their study. Then a half day near the end to look over the findings. Then the last time to write up the report. Usually, clearly labeled tables or bar graphs are best, showing raw numbers or percents. Programs like ClarisWorks can do these.
Mentors can help with simple statistics like correlations, chi squares, and t-tests if needed.
We didn't use numbers. Look for the major themes. Then put quotes from students or your notes as the evidence under the theme. You have many measures, so if one didn't work out, you can omit it. We didn't find what we expected That's okay.
