12. For the following scores, find the mean, median, sum of squared deviations, variance, and standard deviation:
1,112; 1,245; 1,361; 1,372; 1,472
A psychologist interested in political behavior measured the square footage of the desks in the official office for four U.S. governors and of four chief executive officers (CEOs) of major U.S. corporations. The figures for the governors were 44, 36, 52, and 40 square feet. The figures for the CEOs were 32, 60, 48, 36 square feet.
- Figure the means and standard deviations for the governors and CEOs.
- Explain, to a person who has never had a course in statistics, what you have done.
- Note the waus in which the means and standard deviations differ, and speculate on the possible meaning of these differences, presuming that they are representative of U.S. governors and large corporations’ CEOs in general.

a. an automony deprivation condition, in which they were told to follow instructions precisely, constantly given instructions over a loudspeaker, and carefully observed on everything they did.
b. a neutral condition, which was much more laid back.
After this activity, they were asked to do a “lexical task” (a standard approach for measuring unconscious responses) in which they were shown a series of words and nonwords in random order and had to press “C” if it was a real word or “N” if not. Half of the real words were related to autonomy (e.g., freedom, choice) and half were neutral (e.g., whisper, hammer). The key focus of the study was on how long it took people to press the button *(“response latency”) for each kind of real word, averaged over the many words of each type. The table below shows the mean and standard deviation across the participants of these four categories of results. Thus, for example, 782 milliseconds (thousandths of a second) is the average time it took participants in the autonomy-deprived condition to respond to the autonomy-related words, and 211 is the standard deviation across the 26 participants’ average response time in that condition. Explain the numbers in this table to a person who has never had a course in statistics. (Be sure to explain some specific numbers, as well as the general principle of the mean and standard deviation.) For your interest, the pattern of results shown here supported the researchers’ hypothesis: “Relative to a neutral instructional climate, a controlling climate thwarting the need for autonomy…enhanced accessibility for autonomy-related words.” (p.924).

14. On a standard measure of hearing ability, the mean is 300 and the standard deviation is 20. Give the raw scores for persons whose Z scores for persons who score 340, 310, and 260. Give the raw scores for persons whose Z scores on this test are 2.4, 1.5, and -4.5.
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.
