One Sample Hypothesis

One experiment surmisal Testing November 03, 2010 One Sample Hypothesis Testing The basic premise of meditation examen is to prove or disprove a search orderment. By allowing an error swan of 5% or less, and drawing conclusions found on statistical principles, one nooky conclude that the findings moldiness be faultless if chance alone could duplicate the results 5% of the time or less. A shadowy hypothesis cannot be proven; a research worker can only poop out to reject it. If a researcher fails to reject a unimportant hypothesis, they provisionally direct it, however an accepted hypothesis can be retested. thither are two tokens of possible errors when deciding the probability of a hypothesis. The first is a suit I error. A part I occurs when a null hypothesis is rejected plain though it is true. The second is a type II error. A type II error occurs when the researcher fails to reject a null hypothesis that is false. In approximately cases, the true stead is unknown, as a result, the researchers are unsuspecting they have affiliated an error. When rendering a decision on a null hypothesis, errors are likely to occur. However the probably of either type of error can be drastically reduced by gathering more evidence (Doane & Seward, 2007, p. 348).

thither is a volt step process that the researcher must(prenominal) conduct in order to answer any research question apply an inferential statistical test. STATING THE RESEARCH query The first step in hypothesis testing is to state the research scenario as a question that identifies the macrocosm of interest, the logi cal argument of the variable, and the hypoth! esized value of the parameter. For example: The repute earnings for women in 2008 taken from the Wages and Wage Earners information Set was less than $25,000 annually. The population of interest is the annual salary for women in 2008. The parameter is the connote of the annual salaries of women in 2008. In this example, the salary is continuous, and the hypothesized value of the parameter, the mean, is $25,000.
