Q General Guidance: You should read through this week's assigned lab and/or Peerceptiv material before you make your post, so that your post will be informed, and you avoid posing a question that is answered in the course materials. General Format: You are required to make ONE post to each week’s lab discussion board. Your required post must contain 50 words at minimum and be written in your own words. Your grade will be determined by your demonstration of three areas of communication: application, critical thinking, and writing. Deadline: Your required post is due by 11:59PM, Wednesday. Late posts will be penalized 0.5 points (20%) per day late. NOTE: We recommend that you avoid using the smartphone/tablet Canvas app when submitting your discussion post, because the app frequently fails to associate posts with your corresponding discussion group. ________________________________________ This Week's Posting Prompt: Address at least ONE of the following prompts: Please review the following Table 2 before addressing any of questions 1-3: Pictured is a data table from a student who performed the same light germination experiment (she let hers go for 7 days, rather than the required 5 days). These data are the length of the hypocotyl of germinated seeds from the 5 light treatments. (n/a means not available because not enough seedlings germinated in that treatment.) 1. Could we analyze these data with a statistical test? If so, what conclusion would we draw? Pick a test, do the analysis, and post the results. 2. What would the null and alternative hypotheses be for an analysis of the above data? 3. If there are significant differences in the above data set, what do you think is the biological reason for these differences in the growth of lettuce seedlings? Please read through the instructions for the gravitropism experiment before addressing any of the following questions 4-10: 4. What is your hypothesis and prediction for the treatments? 5. What is the biological explanation for your hypothesis and predictions? 6. Are they any things about the experimental procedure that were/seem problematic for you? If so, how could the design be improved? 7. Does the gravitropism experiment have a sufficient control? If so, which treatment acts as a control? 8. Next week (week 5), you will begin work on Peerceptiv Assignment 2, which is a results and discussion for the lettuce germination experiments. What is the purpose of results and discussion sections in a paper? (Be sure to review your Writing in Biology Handbook for this.) 9. How are results and discussion sections of a scientific paper related to the introduction and methods? How are these sections different? 10. Should additional references be used for a results and discussion section (i.e. references not cited in the introduction)? Why or why not?
