The development of null and alternative hypotheses was a difficult task for us at first. I think that people might have had issues understanding exactly what the difference was. I know that I myself had difficulty at first and ended up listening to the archived chats and reaching out to other members of my group for help. After doing all this and conducting some research online‚ I was finally able to grasp the concept. As the group communicated back and forth it was evident that we all agreed on

Don’t “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

TYPES OF HYPOTHESES There are three types of hypotheses which will be explored here: • Research Hypotheses Research hypotheses are most nearly like hypotheses defined earlier. A research hypothesis is a statement of what the researcher believes will be the outcome of an experiment or a study. Before studies are undertaken‚ business researchers often have some idea or theory based on experience or previous work as to how the study will turn out. These ideas‚ theories‚ or notions established

Theories and Hypotheses: The Differences and Similarities Abstract This paper is an examination of theories and hypotheses‚ their differences and similarities. The four major types of theories studied are Deductive‚ Inductive‚ Grounded and Axiomatic. Each type of theories is introduced and explained. Additionally‚ a hypothesis is defined in relation to a theory‚ and the key differences between the two explained. The variables which exist between the theories

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

In Example 2‚ the independent variable is violence (mild vs. none)‚ and the dependent variable is aggressiveness on the playground. The hypotheses in Examples 1 and 2 are examples of directional hypotheses. In a directional hypothesis‚ we predict which group will be higher or have more of something. Sometimes we have a nondirectional hypothesis. Consider Example 3. Example 3 It is hypothesized that the child-rearing
