Statistics Investigation Essay

from the null hypothesis, which was expressed as having a unit root. Next, performing t-test, meanwhile, comparing the value of t-statistic with test critical values under the selected confidence interval. When the value of t-statistic was larger than the critical value, the null hypothesis would not be rejected, meaning the existence of the unit root. If the t-statistic value was smaller than the critical value, one rejected the null hypothesis, which implies that the financial time series is stationary

The main idea of the current paper is to provide a well-constructed analysis of the article titled “Meta-analysis of thoracic epidural anesthesia versus general anesthesia for cardiac surgery” written by Svircevic, van Dijk, Nierich, Passier, Kalkman, van der Heijden, and Bax in 2011. In doing so, this author attempts to validate the overall quality of the research being presented and its applicability to the nurse anesthesia practice. Study Design The meta-analysis was hypothesis driven while research

t-test was conducted. Results The SPSS analysis provided a mixed gender group setting mean of 46 smiles with a standard deviation of 12. The same gender group setting produced a mean of 18 smiles and a standard deviation of 7. The descriptive statistics measured a nearly 4 times increase in the mean number of smiles and laughter in the mixed gender compared to the same gender groups. The independent t-test results provided a p-value equal to zero and therefore less than the significance level of

given to SIUE students every day. Our group chose to conduct an experiment that proves that students prefer Starbucks to Kaldi’s. To ensure we got the best results, we created an eight-question survey, which we used as factors in our descriptive statistics and regression outputs. They included: how old are you, what school are you in, what gender are you, do you prefer Starbucks or Kaldi’s, do you enjoy a treat with your drink, do you prefer a store or out in the open, how many drinks do you get in

After hours of deep research, one would be able to solve how statistics could be done incorrectly. My research was not extreme enough to find the true difference between replication problem and replication crisis, nevertheless, a replication crisis is when a scientist finds results of many scientific experiments that are usually impossible to replicate on subsequent investigation. While a replication problem in social sciences would be that the scientists are not interested in experiments that have

The restaurant is seen have various issues that surrounds its operations and the profitability as well. This research is deemed at looking at the various tenets of success that surrounds this restaurant. Again the failure that affects this restaurant is worth noting down. To this end, the performance of this restaurant is

influencing performance of start-up businesses in Northampton United Kingdom. According to Cooper and Schindler (2003), a descriptive study is concerned with finding out what, where and how of a phenomenon. This method is concerned with the intense investigation of problem solving situations in which problems are relevant to the research problem. This design was used to understand underlying factors of each variable in being researched. A correlational research design aims at establishing relationships
