Sample Populations and Designs of Probability and Nonprobability
An 8 page paper that begins with a statement explaining target population and sample population. The first part of the paper explains different non-probability designs, including purposive, convenience and volunteer. Probability designs are then discussed, including simple random designs, stratified, systematic, cluster and multi-stage with examples. Bibliography lists 4 sources.
Sampling and Probability
This is a 5 page paper discussing probability sampling. To properly understand inferences within a population, researchers have developed methods of sampling which combine with the concept of probability to acquire the desired results. There are various types of probability sampling each of which has its own advantages in regards to capturing a specific trend within the population. Sampling sizes are based on several factors as well which include level of confidence, population size, and sampling error among other factors.

Student Supplied Case Study on Probability
This 3 page paper examines a probability cases presented by the student. A couple are convicted of a crime based on their description and the statistical probability of the couple being a 1 in 12 million chance, calculated with independent variables. The paper looks at how and why the conviction may have been overturned at appeal, considering the way the probability was calculated and the way that probabilities were determined in the first place.
Identity Testing and DNA
A 2 page paper discussing the probability of identity through DNA testing. Long used for paternity testing, forensic databases even now are being constructed listing genotypes of known and convicted offenders. Improvements in test procedures and sensitivity has resulted in probability of identity increasing from 1 in 5,000 to 1 in 82 billion in recent years, making DNA testing one of the most reliable methods of proving identity.
