Mean Weights of Boys Ages 2 to 12
I'm using this for Modeling Linear Associations. It has a decent linear correlation coefficient. A linear regression produces the stats and scatter plot with a polynomial of order one trend line overlay which can be used to illustrate extrapolation/interpolation, error estimates, and model breakdown. For over/underestimates and error, interpolate mean weights for 3 and 5 year olds and compare with observed mean weights of 31.0 pounds and 40.5 pounds, respectively. For model breakdown, adjust the x-axis of the scatter plot to range between 0 and 20, with integer tick marks, and the y-axis to range between 0 and 200, with tick marks 0, 10, 20, ..., 200, and an extrapolation for mean weight at age 20 will suggest a weight somewhere near 135 lbs for a 20 year old male.

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.

HeartAttack.xlsx
This data set records information from 480 patients from the Worcester Heart Attack Community Surveillance Study; the subjects are patients who had suffered a heart attack (myocardial infarction) and were treated in one of the16 acute general hospitals in the Worcester, Massachusetts Standard Metropolitan Statistical Area. The patients included here are from the start of the study in December 1975 until 1988, although the study continued until 2006. Results based on this study have been published in many reports, including Goldberg RJ, Gore JM, Alpert JS, Dalen JE. Recent changes in attack and survival rates of acute myocardial infarction (1975 through 1981). The Worcester Heart Attack Study. JAMA. 1986 May 23-30;255(20):2774-9. The data were published in Hosmer D.W. and Lemeshow, S. (1998) Applied Survival Analysis:Regression Modeling of Time to Event Data, John Wiley and Sons Inc., New York, NY

Time of Birth, Sex, and Birth Weight of 44 Babies
NAME: Time of Birth, Sex, and Birth Weight of 44 Babies TYPE: Observational SIZE: 44 observations, 4 variables DESCRIPTIVE ABSTRACT: The dataset contains the time of birth, sex, and birth weight for each of 44 babies born in one 24-hour period at a Brisbane, Australia, hospital. Also included is the number of minutes since midnight for each birth. SOURCE: The data appeared in the Brisbane newspaper _The Sunday Mail_ on December 21, 1997. VARIABLE DESCRIPTIONS: Columns 1 - 8 Time of birth recorded on the 24-hour clock 9 - 16 Sex of the child (1 = girl, 2 = boy) 17 - 24 Birth weight in grams 25 - 32 Number of minutes after midnight of each birth Values are aligned and delimited by blanks. There are no missing values. STORY BEHIND THE DATA: Forty-four babies -- a new record -- were born in one 24-hour period at the Mater Mothers' Hospital in Brisbane, Queensland, Australia, on December 18, 1997. For each of the 44 babies, _The Sunday Mail_ recorded the time of birth, the sex of the child, and the birth weight in grams. Additional information about these data can be found in the "Datasets and Stories" article "A Simple Dataset for Demonstrating Common Distributions" in the _Journal of Statistics Education_ (Dunn 1999). PEDAGOGICAL NOTES: The data can be used to demonstrate fitting the binomial distribution (the number of boys/girls born out of 44 births), the geometric distribution (the number of births until a boy/girl is born), the Poisson distribution (births per hour for each hour), and the exponential distribution (times between births). The normal distribution is found to be unsuitable for modeling the birth weights, but better results are obtained when birth weights are separated by sex. The dataset can also be used to illustrate hypothesis tests about proportions, comparisons of birth weights by gender, the runs test of randomness of gender, and skewed data. REFERENCE: Steele, S.
