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.

gss2008-short.xls
The General Social Survey (GSS) conducts basic scientific research on the structure and development of American society with a data-collection program designed to both monitor social change within the United States and to compare the United States to other nations. The GSS data sets contain a standard ‘core’ of demographic and attitudinal questions, plus topics of special interest, representing the population of American adults, 18 years of age or older. More information about the GSS and its original data sets can be found at http://www.norc.org/GSS+Website/. This is part 1 of the original data.

Sleep Deprivation Study
Does sleep deprivation have harmful effects on cognitive functioning three days later? Stickgold, James, and Hobson (Nature Neuroscience, 2000) investigated this question by providing training to 21 volunteer subjects followed up by an initial test. The subjects were then divided into two groups: one group was deprived of sleep following the test, and the other group was permitted unrestricted sleep after the test. Both groups were then allowed as much sleep as they wanted on the following two nights. All subjects were then re-tested on the third day. This data set contains the improvement as measured by the difference between the two exam scores (second - first) and the sleep conditions imposed on the subject. Note that a negative value indicates a decrease in performance.

Arctic sea ice volume
units: Thousand cubic kilometers The data that was used was collected through a coupled ice-ocean model known as the Pan-Arctic Ice-Ocean Modeling and Assimilation System. PIOMAS was developed at the Polar Science Center, University of Washington. Variances in arctic sea ice volume are calculated on a daily basis relative to the average over the years of 1979-2013. The averages of the months of March and September were taken and recorded in my data set to compare the arctic ice volume of these months over the period of 1979-2013.

Singfat Chu diamond ring data
NAME: Diamond Ring Pricing Using Linear Regression TYPE: Random sample SIZE: 48 observations, 2 variables DESCRIPTIVE ABSTRACT: This dataset contains the prices of ladies' diamond rings and the carat size of their diamond stones. The rings are made with gold of 20 carats purity and are each mounted with a single diamond stone. SOURCE: 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. VARIABLE DESCRIPTIONS: Columns 6 - 8 Size of diamond in carats (1 carat = .2 gram) 16 - 19 Price of ring in Singapore dollars Values are aligned and delimited by blanks. There are no missing values. STORY BEHIND THE DATA: Data presented in a newspaper advertisement suggest the use of simple linear regression to relate the prices of diamond rings to the weights of their diamond stones. The intercept of the resulting regression line is negative and significantly different from zero. This finding raises questions about an assumed pricing mechanism and motivates consideration of remedial actions. PEDAGOGICAL NOTES: This dataset can be used to illustrate model-building in linear regression. A possibly counter-intuitive negative intercept may be avoided by using a multiplicative or exponential regression model. These regression models are intrinsically linear, and they are estimated using standard linear regression technology after a suitable transformation of the data. Additional information about these data can be found in the "Datasets and Stories" article "Diamond Ring Pricing Using Linear Regression" in the _Journal of Statistics Education_ (Chu 1996).
