PROMOTING BAD STATISTICS. Society | March 01, 2001 | Best, Joel In contemporary society, social problems must compete for attention. To the degree that one problem gains media coverage, moves to the top of politicians' agendas, or becomes the subject of public concern, others will be neglected. Advocates find it necessary to make compelling cases for the importance of particular social problems. They choose persuasive wording and point to disturbing examples, and they usually bolster their case

It is important that the title be both brief and descriptive of your research. Search engines will use the title to help locate your article. Readers make quick decisions as to whether they are going to invest the time to read your article largely based on the title. Thus, the title should not contain jargon or vernacular. Rather, the title should be short (generally 15 words or less) and clearly indicate what the study is about. If in doubt, try to specify the cause and effect relationship in your

Nursing Research Critique Assignment Kaplan University Nursing Research Critique Assignment I will be critiquing two different articles. Both studies are nursing studies that evaluate outcomes. I will be following specific key points for a quantitative perspective and a qualitative perspective. There is a guideline that I will be following for each article that includes identifying and examining the data collection and data analysis methodologies used in each study. The names of the articles

occurrence?" Appropriate Probability Concepts and Your Application of Them to Find Resulting Data To Limit the Uncertainty of this Decision Probability theory is an important part of statistical theory that bridges descriptive and inferential statistics. It is the science of uncertainty, chance or likelihood (Cooper & Schindler, 2008). There are three kinds of probability; classical, empirical and subjective. In this instance, we will focus on a mixture of empirical probability which is based

and not observed statistics. Step B: Test statistic We calculate a test statistic from the data. There are different types of test statistics. This chapter introduces the one-sample z-statistics. The z statistic will compare the observed sample mean to an expected population mean μ0. Large test statistics indicate data are far from expected, providing evidence against the null hypothesis and in favor of the alternative hypothesis. Step C: p Value and conclusion The test statistic is converted to a
