1970 Draft Lottery Data
In 1970, Congress instituted a random selection process for the military draft. All 366 possible birth dates were placed in plastic capsules in a rotating drum and were selected one by one. The first date drawn from the drum received draft number one and eligible men born on that date were drafted first. In a truly random lottery there should be no relationship between the date and the draft number. However, this dataset suggests that men born later in the year were more likely to be drafted.

RegisteredNursesSurvey.xlsx
For what survey produced it, see http://www.statcrunch.com/5.0/survey.php?surveyid=8178&code=YINVQ and inputs of all team mates. Towards the end, some validation was done, deleting data where working hours was less than a work day, or outliers to legally admissible work days. Finally arbitarily long chains which were less likely to be encountered in draws of simulated data (M/F, Degrees etc.. were discarded). A total of 12 observations were thus thrown out. All Credit goes to Team 3,the Instructor, our unnamed Friends in the Nursing profession who enthusiastically did a last minute push through over their extended social media groups for data and the respondents who kindly took out time for the survey. Another thought is about the distribution of hours worked. Wven if random, it "should be" "centered on" certain hours a day* number of days, with deviations from centre penalised, while picking a sample.. The observations 38 appear many times for example, however without an explainable reason (we are talking of work-distribution among nursing staff sample) So do "primes" "47, 37, 29" It is not to argue that they "shouldn't occur", but there has to be some reason for their being so significant/vibrant. At this stage we may conclude that most of the respondents may not have been under full-time nursing employments in strict sense of the term. 42, 48,72,60, 50,40 appearing more often would give us less variation but more regularity in the data. Since we haven't tried stratification, we do not know "how often they should occur". We thus do not re-draw observations.

statistics.ods
I began this survey in order to pick out certain factors that may have been linked to students withdrawing from college courses, during the Fall 2010 semester at Ventura College; once the withdrawel deadline passed. Factors include gender, number of units, mode of transportation (whether public or personal), and employment status. My hypothesis was that students who fulfill one or more of the following factors, are more likely to withdraw from classes: students who are employed, rely on public transportation and are full time students. I collected the data for this research by randomly interviewing students from Ventura College.

Eggs
A single can of dried eggs was stirred well. Samples were drawn and a pair of samples (claimed to be of two "types"), was sent to each of six commercial laboratories to be analyzed for fat content. Each laboratory assigned two technicians, who each analyzed both "types".

Cuckoo
L.H.C. Tippett (1902-1985) was one of the pioneers in the field of statistical quality control, This data on the lengths of cuckoo eggs found in the nests of other birds (drawn from the work of O.M. Latter in 1902) is used by Tippett in his fundamental text. Cuckoos are knows to lay their eggs in the nests of other (host) birds. The eggs are then adopted and hatched by the host birds. The data are all in millimeters.
