Statistical Analysis and Initial PreparationName __________________________________________Course and
Section_______________ 1) What is the number of your case study? ________ 2) What was Sara's observation in the case study that you selected? This is
an important question because the scientific way of learning begins with an
observation. Next, a hypothesis is created to explain the observation (step 3
below). Reread the case study to answer this question. The answer is in the case
study.
3) State your hypothesis. Use a complete sentence (or sentences). Your hypothesis must explain Sara's observation.
4) State how you tested your hypothesis. Provide enough detail that the reader could repeat your experiment. Depending on your experiment, dates, time of day, temperature, location, etc. may be important information and should be included in the methods section. If you used a reaction time website, the URL should be given. This question should be answered using whole sentences and paragraphs.
5) How does your hypothesis explain Sara's observation?
6) Enter your two groups of data in the table below. Tell what each group is in the first row. For example, Group 1 might be the reaction time of your experimental group and Group 2 might be the reaction time of your control group. You should also indicate the units (seconds, beats per minute, etc.) You should have one number for each person in each group. For example, if your hypothesis is about recovery time, you should have one time for each person. If you have a total of four people, you should have two numbers (two times) for group 1 and two for group 2.
7) What is the probability that the means of the two groups do not differ (that the difference is due to chance)? p = 8) Do you accept your hypothesis or do you reject your hypothesis? 8) Explain why you accept or reject your hypothesis. Your answer must mention how the value of p is used to determine if the hypothesis is accepted or rejected. 9) Attach a printout of your statistical analysis (t-test). IMPORTANT- Please do not submit this assignment without a statistical analysis attached. It will not be graded without the analysis.

Information for answering this question can be found in the plagiarism document in The Biology Web. Click here to view the course policy on plagiarism.
11) List two of your literature sources below using APA format. Do not use encyclopedias, or text books. All sources must have an author name. If you use the internet, it is best to avoid web pages. Instead, use books, journal, or magazine articles that are online. See the CCC library web page if you need instructions on APA format. You may decide to use different sources when you write the formal report. It is OK to change your mind; the sources listed below do not need to be the same ones that you use in your report. All members of your group must have different sources.This assignment will not be graded unless two appropriate sources of literature are listed below.
12) Make photocopies or printouts of the two sources and attach them to this
page. If your source is online, you can print it and attach it. If it is a
journal or magazine, you can make a photocopy. If it is a book, make a photocopy
of the page that contains the information that you plan to use. |
