Statistical hypothesis testing

Furthermore, university enrolment rate, government expenditure on R&D, high-tech market, patent and scientific journal published are statistically significant in the fixed effect model. The coefficients of these variables as a measure of national innovation system are positive and statistically significant at the 1% and 5% levels of significance which implies that national innovation system as a whole has a positive effect on economic growth in BRICS economies and in consequence spurs their…

Condominiums for Sale The cost or real estate can differ from region to region and with size and quality. One factor that greatly effects the sale of a piece of property with a view. Such is the data that will be analyzed herein. Can the data support the fact that there will be buyers willing to pay more for a condominium with a view? Consequently, would a comparable home without a view that is considerably less expensive actually take longer to sell? Overview of the Condominiums for sale The…

(two-tailed) is .000 for Facebook, Instagram and Snapchat. This is below the pre-specified alpha of 0.05. Therefore, there is a significant statistical difference between these three social networking sites. However, the Sig (two-tailed) for Twitter, YouTube and Tinder has a higher pre-specified alpha of 0.05, which means that it does not have a significant statistical difference between these three social networking sites. Further analysis also found out that “social media takes up more time…

This September, I started my MSc at UBC SPPH with a goal of becoming a researcher on clinical trials. During the past semester, I discovered I love it more than I could imagine. I enjoy everything that I am doing, especially my research which I can work until 3 am in the morning without feeling tired or exhausted. I count myself as a fortunate person as I have found what I love, unlike many other people who spend their entire life looking for what they like. However, as a person who wants to…

Attribute selection is the process of identifying and removing as much of the irrelevant and redundant information as possible from a dataset. If the data dimensions are reduced, we will be able to improve the performance of the applied classification algorithms. They will function faster, more efficiently and will be with an improved classification accuracy. As an addition we can also execute data visualization, and increase the insight of the potential classification model [] . There are many…

Out of all, the burned area showed a significant increase in longleaf pines, (Pinus Palustris) and a decrease in woody species, compared to the unburned area. In fact, it jumped from a frequency of 15 in the unburned area to a frequency of 50; which is two times that of the burned area (see figure 1). Compared to all other species of tree, Pinus Palustris experienced the most increase of frequency. Whereas, Pinus Clausa or sand pine, was only present in the burned area showing that it was a…

Behavioural Ecology Comparison between the roaring rate of the red deer in Richmond Park and in wildlife R ed deer males use a deep guttural vocalization (roar) to attract females. Previous studies have correlated high roaring rates to higher reproductive success. In this study, we investigated the influence of living in a limited area such as Richmond Park (RP), with direct human contact in roaring rate of red deer. The roaring rate of three males living in RP were calculated and compared to…

In schools where students fail to achieve state achievement standards in reading and math does instruction geared towards social-emotional intelligence support academic goals? If so, what if any approaches demonstrate documented success in the classroom environment? What place do the practices of Eastern religions have in a secular classroom? The answers to these questions are revealed through an exploration of mindfulness curriculum. The social-emotional stresses of poverty are thoroughly…

It is also important to consider the time that the SI session starts because some students are either too busy to go to the session or have other important appointments. In addition, the place should be accommodating for the students. I will be testing two different groups: one, being the at risk students and another the control group. The control group will be students who are attending a SI session, but a lower quality one. This means that in the control group, students would not be receiving…
