Null hypothesis

that the p-value “defines the smallest value of alpha for which the null hypothesis can be rejected” (p. 312). When we carry out a statistics test, we are testing the hypothesis that the groups are the same (the null hypothesis). If it is determined that there is a p value of 0.05 or lower, than the null hypothesis is rejected and the alternate hypothesis is accepted. Likewise, if the p value is higher than 0.05, the null hypothesis should be accepted and the two groups should be measured to be…

purpose of the research is to find out why the staff is unhappy with their jobs, to lower the turnover rate, and make improvements to increase the job quality. The initial information supports the null hypothesis of the high employee attrition rate due to low employee morale. To further verify if the hypothesis is rejected or not rejected, the team analyzed the survey administered to the employees, and the instruments used for data…

INTRODUCTION: Many processes in the world can be studied and analyzed; everything is a process in one way or another. One system that might not be considered a “process” at first glance, but which operates as one, is the education system. If you consider graduation rates, literacy rates, and the general intelligence of an educated populace as the variables being tested, one could determine if the education system is in control or reliable. We originally wanted to perform this study to compare…

But they have few different scopes in my alternate hypothesis if true. E.T observer group founder Soylent Green says that “In this instance, the null hypothesis is refuted. It’s false to say that no U.F.O. are controlled by Extraterrestrials. That can easily be refuted based on the mountains of evidence that supports the alternative hypothesis that SOME NOT ALL U.F.O.’s are controlled by an extraterrestrial source. So the alternative hypothesis is more likely to be true than false based on the…

80 degrees Celsius, the catechol will be at its optimal absorbance. The alternate hypothesis tested for this following experiment was that there is a significant relationship between catechol and pH. In contrast, the null hypothesis states that there is no significant relationship between catechol and oxidase and pH. This hypothesis will be supported if the rate of catechol oxidase does not increase. The hypothesis was tested by observing the reaction time of catechol oxidase at four different…

1.20 RESEARCH GAP There are number of studies about employee attrition and retention in various industries belongs to different sectors. Researchers have mainly given importance to study and investigate the employee attrition and retention in IT companies situated in IT hubs and in Tier I cities. These cities are significantly differed in socioeconomic and cultural aspects comparing Tier II cities. The studies on employee attrition and retention in IT companies situated in Tier II cities are…

Hypothesis: Monozygotic female twin partners will end up receiving and earning a higher rating of attractiveness than the monozygotic male twin partners would do in the experiment that was conducted in this article. 3. Method: The hypothesis was tested through an experiment where they had photographs of 16 monozygotic male twin pairs and 18 monozygotic female…

Conclusion The hypothesis stating if certain stimuli (light, darkness, bran flakes, and apple slices) are placed in a chamber near a group of ten mealworms, then during 3 minutes a portion of the mealworms will have moved towards the stimuli, was refuted by the data showing how zero mealworms migrated into the stimulus chamber, during any point in any of the trials using each of the stimuli and the one trial without using a stimulus. Discussion The student designed experiment to investigate a…

My website results gave me that I was “The Logistician.” I am the ISTJ personality which stands for Introvert, Sensing, Thinking, and Judging. My results said that I was 51 percent introvert, 51 percent sensing, 72 percent thinking, and 51 percent judging. I am on the line of being other personalities, seeing that three of my results were 51 percent. I think that it is true, though, I am introverted around other people that I don’t know but if I am around people I know, but I can keep up a…

This write-up focusses on three concepts of sound assessment practice namely reliability, feasibility and educational impact. Reliability Reliability refers to the ‘reproducibility’, ‘repeatability’ or ‘consistency’ of the scores obtained from an assessment (Memon et al, 2010; van der Vleuten et al, 2005). Reliability is generally expressed as a coefficient ranging from 0 (no reliability) to 1 (perfect reliability). Since it is difficult to achieve perfect reliability in any assessment, a…
