1.
\nThis research scenario will be familiar to you. Do
\nletters a, b, and c, answering the questions beneath your SPSS output. (3 pts
\nfor output and 2 pts each for a\u00e2\u0080\u0093c)

\nSpearman Rho
\nExercise: This exercise is not found in Green & Salkind. Open the data file
\n\u00e2\u0080\u009cMod8_SpearmanRho_Exercise File\u00e2\u0080\u009d in the Module\/Week 8 SPSS Assignments folder
\nin Blackboard and read the following information; answer the questions below.<\/p>\n
Scenario: During the Vietnam
\nWar, a draft was put in place that selected young men born on certain dates and
\nplaced them in the armed services. The process proceeded via lottery: Dates
\nlike \u00e2\u0080\u009cSept. 14\u00e2\u0080\u009d were placed in capsules, one for each of the 365 days of the
\nyear, and the capsules were then drawn randomly from a container. In the 1970
\ndraft, Sept. 14 was the first date drawn, meaning that all young men born on
\nSept. 14 were eligible for the very first round of the draft, and so on. After
\nthe results of the 1970 draft were analyzed, many statisticians and politicians
\nasserted that the process had not been random at all, and certain men had a
\nhigher chance of being drafted than others. This case is famous, making it to
\nthe pages of international newspapers and the U.S. Supreme Court.<\/p>\n
In the SPSS data file in Blackboard,
\nyou will find the original 1970 draft data with two variables. Column 1
\ncontains the consecutive day of the year (1 = Jan. 1; 2 = Jan. 2; and so on).
\nColumn 2 contains the draft rank (1 =
\nfirst date drawn; 2 = second date
\ndrawn; and so on). So, in the first row of the data set, Day 1 (Jan. 1) had a
\ndraft rank of 305. The lower the draft rank, the sooner and more likely a man
\nwas to be drafted. So, a higher rank (like 305, for example) was preferable to
\nthose who did not want to be drafted right away.<\/p>\n
If the process had been
\nstatistically random, there would be no correlation between the day of the year
\nyou were born and the rank that was assigned to you (r = 0). Any type of
\nsignificant correlation would mean that there was something relating the variables
\nbeyond mere random error, or chance.<\/p>\n
1.
\nOpen the data file and perform a Spearman correlation
\nanalysis for the day of year and the draft rank. Paste your output in the
\nhomework document. (2 pts)
\n2.
\nWrite a current APA-style results section describing
\nthe outcome. (2 pts)
\n3.
\nAnswer the next two questions in \u00e2\u0080\u009clayman\u00e2\u0080\u0099s terms\u00e2\u0080\u009d as if
\nfor someone who does not know much about statistics: (a) Why did people accuse
\nthe process of not being random? (b) What do the data indicate for men born
\nearlier in the year vs. men born later in the year? (2 pts)<\/p>\n
It\u00e2\u0080\u0099s not required, but if you want to check out the original
\nNew York Times article and see an interesting graph, go to this link: .wikispaces.com\/file\/view\/nytimes.pdf”>http:\/\/frewm.wikispaces.com\/file\/view\/nytimes.pdf<\/p>\n

Part 2:<\/p>\n
1. A
\nuniversity assessment department collects data to determine whether class
\nranking differs between male and female students. Based on the top 12 males and
\ntop 12 females of the senior class, is there a difference between genders on
\nwhere they are ranked in their class? Perform a Mann-Whitney U test, being sure
\nto follow the directions on the following page. (3 pts)<\/p>\n
Male<\/p>\n
Female<\/p>\n

Note: Your file must
\nbe set up in the same manner as the example data file and the exercise file
\nfrom Part 1 with a grouping variable and a dependent\/test variable. Because
\nthese are class rankings, they are ordinal data and must be identified as such

\nsatisfaction ratings differ as a function of department (human resources,
\nsales, and research and development) and\/or time of shift (early, late). Choose
