“Accept” the Null Hypothesis by Keith M. Bower‚ M.S. and James A. Colton‚ M.S. Reprinted with permission from the American Society for Quality When performing statistical hypothesis tests such as a one-sample t-test or the AndersonDarling test for normality‚ an investigator will either reject or fail to reject the null hypothesis‚ based upon sampled data. Frequently‚ results in Six Sigma projects contain the verbiage “accept the null hypothesis‚” which implies that the null hypothesis has been proven

understanding of hypothesis testing. The textbook explained the aspects and steps of hypothesis testing in a legible fashion‚ while the video helped demonstrate a real-life application. I learned from the text that hypothesis testing is a “Procedure for deciding whether the outcome of a study (results from a sample) supports a particular theory or practical innovation (which is thought to apply to a population)” (Aron A.‚ Aron‚ E.‚ and Coups‚ 2011‚ p. 145). I also learned that hypothesis testing

STEPS IN SCIENTIFIC RESEARCH: ARCHITECTURAL RESEARCH: AN INTERDISCIPLINARY REALITY Hypothesis is a tentative explanation that accounts for a set of facts and can be tested by further investigation. Generation of Research Hypothesis Research usually starts with a problem. Questions‚ objectives and Hypotheses provide a specific restatement and clarification of the problem statement/research question. In qualitative research‚ the research question may assume two forms: The grand tour

Hypothesis Testing and Nursing Hypothesis testing is a method of making decisions using data from scientific study. In statistics‚ a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone‚ according to pre-determined threshold probability‚ the significance level. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect based on how

Null Hypothesis (McMillan‚ 2012‚ p. 49): A null hypothesis states that no significant statistical relationship or difference exists between the groups that are being compared in astudy. This term relates to all of the studies I read for my research study analyses. They all compared the academic achievement of high school athletes and non-athletes in some way or another. While the null hypotheses were not explicitly mentioned in the studies‚ they all would have been something along the lines of

MM Hypothesis – A Critique The assumptions of MM hypothesis are unrealistic and untenable in practice. As a result‚ the conclusions that dividend payment and other methods of financing exactly offset each other and hence‚ the irrelevance of dividends‚ is not a practical proposition; it is of merely theoretical relevance. The validity of MM approach is open to question on two counts: 1. Imperfection of Capital market 2. Resolution of uncertainty Market Imperfection MM assume that capital markets
