"Applying ANOVA and Nonparametric tests" simulation‚ I realize there were a few things to take into consideration when analyzing a problem. This particular exercise wanted to know the differences and causes of the variation. In order to resolved the solution‚ an individual or whoever is conducting the analysis will need to know what type of test to used‚ decide if the null hypothesis should be rejected or not‚ and make recommendation based on the collected data. Due to two parameters‚ ANOVA and the

Applying ANOVA and Nonparametric test In the simulation‚ I selected the Kruskal-Wallis test which is used when it is difficult to meet all of the assumptions of ANOVA. The Kruskal-Wallis test is a nonparametric alternative to one way ANOVA. This test is used to compare three or more samples‚ to test the null hypothesis that the different samples in the comparison drawn from the same distribution or from distributions with the same median. Interpretation of the Kruskal-Wallis test is basically similar

A 4(amount of alcohol: 0‚ 2‚ 4‚ 6 pints) X 2(type of lighting: dim‚ bright) within subjects Factorial ANOVA was conducted on attactiveness scores of chosen mate. Mauchly’s test indicated that the assumption of sphericity had been assumed for the main effect of alcohol amount‚ χ²(5) = 4.70‚ p > .05 and alcohol amount and lighting type interaction effect‚ χ²(5) = 2.58‚ p > .05. There was a significant main effect of type of lighting on attractiveness of chosen mate‚ F (1‚ 25) = 23.42‚ p

Exploratory research • Exploratory research is most commonly unstructured‚ “informal” research that is undertaken to gain background information about the general nature of the research problem. • Exploratory research is usually conducted when the researcher does not know much about the problem and needs additional information or desires new or more recent information. 1 When to use Exploratory Research Exploratory research is used To gain background information To define terms and

There are several techniques used in Experimental Research and are broken down into several methods of research used in psychology. These research methods are Naturalistic Observation‚ Correlational Method‚ Experimental Method‚ Clinical Method and Survey Method. The Experimental Method is used to give the researcher more control over the experiment. This is the most scientific method of research because the researcher is able to deliberately manipulate the IV (independent variable) while controlling

One-way repeated measure ANOVA In a one-way repeated measures ANOVA design‚each subject is exposed to two or more different conditions‚ or measured on the continuous scale onthree or more occasions. It can also be used to compare respondents’ responses to two or more questions or items. These questions‚ hiwever‚ must be meausred using the same scale.( Likert scale) Example of research question: Is there a change in confidence scores over the three time periods? What you need: One group of participants

Two-Way ANOVA Two-way ANOVA is similar to one-way ANOVA in all aspects except that in this case additional independent variable is introduced. Each independent variable includes two or more variants.
