NY Times: The Most Economically Diverse Top Colleges
To measure top colleges efforts on economic diversity, The Upshot calculated a College Access Index, based on the percentage of freshmen in recent years who came from low-income families (measured by the share receiving a Pell grant) and on the net price of attendance for low- and middle-income families. The recent Pell (2012 - 2014) number for each college is the average percentage of the freshman class that received a Pell grant in 2011-12, 2012-13 and 2013-14; not all colleges had 2013 data yet. The earlier Pell (2008) value is for the fall of 2007. Average net price is the average total cost of attendance in 2012-13, including tuition, fees, room and board, after taking into account federal, state and institutional financial aid, for students who come from households earning between $30,000 and $48,000 a year and qualifying for federal aid. Endowment per student is for the year 2011-12 and includes graduate students. The College Access Index is a combination of net price and the Pell average for 2011, 2012 and 2013, using a statistical technique known as a z-score. A college with an average score on the two measures in combination will receive a zero.

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.

Diamond Ring Prices.xls
The source of the data is a full page advertisement placed in the Straits Times newspaper issue of February 29, 1992, by a Singapore-based retailer of diamond jewelry. The advertisement contained pictures of diamond rings and listed their prices, diamond content, and gold purity. Only 20K ladies' rings, each mounted with a single diamond stone, were considered for this study. 20K rings are made with gold of 20 carat purity. (Pure gold is rated as 24K.) There were 48 such rings of varying designs. The weights of the diamond stones ranged from 0.12 to 0.35 carats (a one carat diamond stone weighs 0.2 gram) and were priced between $223 and $1086. The jewelry store adopted a fixed-price policy. How Is Jewelry Priced? In Singapore, the pricing of gold jewelry is simple. The price equals the current market value of the gold content (i.e., weight times the going rate per gram of gold) plus a craftsmanship fee. However, the pricing of other jewelry like diamond rings is more complicated because they are not as standardized as gold jewelry. The price of diamond jewelry depends on the four C's: caratage, cut, colour, and clarity of the diamond stone. A good cut gives a diamond more sparkle. Colourless diamonds are the most prized. A flawless diamond has maximum clarity because the passage of light is unimpeded through the stone. Cut, colour, and clarity are subjective factors and are very hard for the layman to gauge.

Telephone Holding Times
An airline has a toll-free phone number that they use for reservations. Sometimes callers have to be placed on hold. The airline conducted a randomized experiment to determine if there was a significant difference in how long a caller would remain on hold depending on what is playing on the call. The airline randomly selected one out of every 1000 calls to be placed on hold with either a advertisement of current promotions, with muzak playing (elevator music), or with classical music playing. Total, 15 callers were sampled for this study. Each column is the number of minutes that the random caller remained on the line until they hung up for each type of recorded message. This data set comes from "Statistics: The Art and Science of Learning from Data" by Alan Agresti and Christine Franklin.

Project Data
This data encompasses the results of surveying 50 of my women friends, who exercise regularly, in order to determine the average resting heart-rate of females who exercise regularly. I define exercising "regularly" as doing a set aside workout of at least 20 minutes, at least 4 times a week. For my research I stayed within an age group range of females ages 18-22 years old.
