Chi- Square Goodness of Fit Testing Assuming Equal Expected A handful of students loves numbers and selects a major in Finance, Statistics, or Marketing. While others prefer a major in Leadership or are undecided. Historically, the MBA program at Whatsamatta U has about 40% of their students electing Leadership as their major, 30% selecting Finance as a major, 20% choosing Marketing, and 10% are undecided. Conducting a Chi-Square Goodness of the Fit Test revealed that the class of 200 students…

There is little doubt public education in the United States is under intense scrutiny from the American public in recent years. In Mississippi, years of negative student outcomes have created a great deal of negative publicity for the state’s public schools. It is important for educators, whether at the district level, research level, or policymaking level, to continue to study available data to identify areas of weakness with the realm of education and work collaboratively to remedy those…

It is well known that the temperature that a plant is grown in greatly affects the manner in which that plant grows. If the conditions are too extreme for a plant, then that plant cannot be as productive as other members of its species grown at less extreme temperatures. Such is the case of the pepper or tomato plant; if temperatures are too high for these plants, then the pollen these plants produce becomes inviable and these plants cannot successfully reproduce (Environmental Factors That……

RESULT & OBSERVATION The hypothesis for statistical testing must be written as Null hypothesis (H0) and Alternate (Research) hypothesis (H1) form. H0 1= There is no significant relationship between body height, foot length and knee height in both the sexes. H1 1= There is relationship between body height, foot length and knee height and are significant in both the sexes. H0 2= Body height is equally…

In Willems et al’s study of proprioception deficits among athletes with high rates of recurring lateral ankle sprains, they found that almost all of their subjects tended to under shoot the needed ankle during the test (Willems et al., 2002). In this study they had 4 groups of athletes to study. The control group were individuals who had no prior ankle injuries (Willems et al., 2002). The Instability group were individuals that had suffered from more than three inversion sprains and complained…

¥ For how many students do you have Verbal Aggressiveness scores? We have Verbal Aggressiveness scores for 59 students. ¥ What is the mean for the entire sample? The mean for the entire sample is 44.0169. ¥ How do you interpret the mean score? When we interpret the mean score, we should look at the minimum and the maximum scores, so we can see the mean are close to each one. In verbal aggressiveness, the minimum is 26 and the maximum is 65, which indicates that the mean around the middle of…

In the experiment conducted by W. Scott Terry, they set out to find out whether the placement of a commercial in a set of commercials would impact the ability for a person to recall the specific commercials and specific details from said commercials. They wanted to know whether there would be primacy or recency effect when recalling information. The serial position for the capability to recall the commercials under naturalistic conditions was an important factor for how people were able to…

(Harrington, Bosch, Schools, Beel-Bates, Anderson) Yes statistical significance was presented and insignificant. The results were not compelling findings. Many of the test scores did not show which testing style was more appropriate to teach with. Limitations are constricting to studies and this one holds a large…

Birth weight exceeding the 94th percentile showed statistical significance. Feeding problems a few times a week at 6 months and SGA were not statistically significant, indicating that they were not interpreted accurately in reference to the measures of association. The relative risk for SGA was 0.5, which…
