five steps of hypothesis testing and the 5% significance level (i.e. alpha = .05)‚ does showing the film change students’ attitudes towards the chronically mentally ill? What does it mean to set alpha at .05? Alpha means making a Type I error same as significance level. When the alpha is at .05 it means that the researcher doesn’t want to take a big risk therefore sets the alpha to .05. By doing this it will make it hard for hypothesis testing process to reject the null hypothesis unless it is

The experiment proves that density is an intensive property. The density of an object remains the same no matter how much of it is present. The density is an intensive property because mass and volume changes at the same rate. Introduction: This experiment was designed to determine if density is an intensive or extensive

The skeptical hypothesis seeks to undermine the credibility of our knowledge by making a claim about the falsity of our beliefs that we cannot disprove. I will explain this hypothesis in further detail and outline two responses to it‚ the Moorean response and the contextualist response. Finally‚ I will argue that the Moorean response is the most logically sound of the two‚ while considering a counterpoint to the Moorean philosophy. The skeptical hypothesis argues that for anything that one might

Stock Market Prices Do Not Follow Random Walks: Evidence from a Simple Specification Test Andrew W. Lo A. Craig MacKinlay University of Pennsylvania In this article we test the random walk hypothesis for weekly stock market returns by comparing variance estimators derived from data sampled at different frequencies. The random walk model is strongly rejected for the entire sample period (19621985) and for all subperiod for a variety of aggregate returns indexes and size-sorted portofolios. Although
