Violent Crimes by State

State Rankings  Statistical Abstract of the United States
VIOLENT CRIMES 1 PER 100,000 POPULATION  2006
[When states share the same rank, the next lower rank is omitted. Because of rounded data, states may have identical values shown, but different ranks. Cautionary note]
Cautionary note about rankings
The ranks in some tables are based on estimates derived from a sample(s). Because of sampling and nonsampling errors associated with the estimates, the ranking of the estimates does not necessarily reflect the correct ranking of the unknown true values. Thus, caution should be used when making inferences or statements about the states' true values based on a ranking of the estimates. As an example, the estimated total (average, percent, ratio, etc.) for State A may be larger than the estimates for all other states. This does not necessarily mean that the true total (average, percent, ratio, etc.) for State A is larger than those for all other states. Such an inference typically depends on among other factors the size of the difference(s) between the estimates in question, and the size of their associated standard errors.
In other tables, the ranks are based on a complete enumeration of the target population, or on complete administrative reporting from the population. In such cases, sampling is not used, and there is no sampling error component in the estimates. Still, care should still be taken when making inferences or statements based on the rankings. The table values may still exhibit nonsampling error originating from such sources as coverage problems (missing units or duplicates), nonresponse, misreporting, and others.

Annual Movie Data 2008 Random Sampling.txt
This data is a random sampling of movies that played in theaters in 2008. It includes movies released in previous years that earned money during 2008. For example, a movie released over Thanksgiving in 2007 will most likely earn money in 2007 and 2008.
Each box office year ends on the first Sunday of the following year. The next year starts the following day (Monday). For example, the "2004 box office year" ended on Sunday, January 2, 2005.
Inflationadjusted figures are based ticket sale estimates, and may not be precise due to rounding errors.  wikipeterson  Oct 7, 2009  8KB  507

UTA Cola
This data set consists of 10,000 observations. The variable of interest is the actual number of fluid ounces in a 16 ounce bottle of UTA Cola. The population mean is 16 and the standard deviation is 0.1.
This data is useful for demonstrating the concept of random sampling, sampling distributions, confidence intervals, and hypothesis tests.

Simple Random Sample of n=30
Using the Age column, take a Simple Random Sample (SRS) of n=30. Show the sample and explain how you took the sample.
Use StatCrunch sampling, Excel Analysis Toolpak sampling, or Excel function Randbetween (using row numbers). Taking the first 30, or every 5th row, or other such schemes are NOT random.  lethamfrancis  Mar 31, 2014  631B  397

Deal
This table lists the number of wins from playing the Let's Make a Deal applet 50 times with the strategy "stay with door 1 no matter what." These data were generated during Lab 2 (i.e., 1 entry per group) in STAT 215 at WVU and will be reused later in this course to illustrate sampling distribution concepts.  kjryan  Sep 6, 2017  110B  48  Lab 11.1
