Question #3: Develop and state your own research hypothesis and its corresponding two statistical hypotheses [i.e., the alternative hypothesis (H1) and the null hypothesis (H0)]. Describe the relationships between the two statistical hypotheses; the relationship between the alternative hypothesis and the research hypothesis; and state the two possible results after hypothesis testing. How do Type I and Type II errors relate the alternative and null hypotheses?

Question #4: Ivan adopted a 3 x 4 mixed factorial design to study the effects of A and B on a dependent variable. Factor A (IV #1) is a between-subjects variable. Factor B (IV #2) is a within- subjects (repeated) variable. In order to control for possible order effects, Ivan decided to use complete counterbalancing. Please answer the following questions and justify your answer.

(a) How many groups of participants are required in Ivan’s experiment?
(b) How many conditions need to be counterbalanced?
(c) How many sequences need to be enumerated? Why?
(d) If Ivan wanted to include five participants for each sequence, then, how many participants are

required in his experiment?

Question #5: Educational psychologists were interested in the impact the “Just Say No!” Programand contracts on drunk driving among teens. This program was a pilot program. The investigators identified gender as a participant characteristic highly related to alcohol use among teens that would require a matching strategy and analysis statistically. With the cooperation of school officials, 16- year-old students were matched and randomly assigned with equal numbers of males and females in each group. Group A participated in a “Just Say No!” program, which required a one-hour information session instead of P.E. for six weeks. Students were presented with written factual information, motivational lectures, guidance films, and assertiveness training. Students were also encouraged to sign a personal responsibility contract that stipulated that they would not drink and drive. Group B participated in regular P. E. classes for the six-week experimental period. A two- factor factorial analysis was used to analyze the data. Please answer the following questions and justify your answer.

(a) Identify the experimental design.
(b) What is the independent variable? What is the dependent variable?
(c) Diagram this experimental design.
(d) What are the potential confounds?
(e) How many main effects, interaction effects, simple main effects of A, and simple main effects

of B are there?

ADDITIONAL INSTRUCTIONS FOR THE CLASS

Discussion Questions (DQ)

• Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
• Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
• One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
• I encourage you to incorporate the readings from the week (as applicable) into your responses.

Weekly Participation

• Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
• In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
• Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
• Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.

APA Format and Writing Quality

• Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
• Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
• I highly recommend using the APA Publication Manual, 6th edition.

Use of Direct Quotes

• I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
• As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
• It is best to paraphrase content and cite your source.

 

LopesWrite Policy

• For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
• Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
• Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
• Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.

Late Policy

• The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
• Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
• If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
• I do not accept assignments that are two or more weeks late unless we have worked out an extension.
• As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.

Communication

• Communication is so very important. There are multiple ways to communicate with me: 
  • Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
  • Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
