Suitable P-Value for a Clinical Trial Statistical testing to determine whether results are significant is extremely useful in all types of research. In most cases, where a significant level, or p-value, is being chosen, a p-value of .05 is deemed t Continue Reading...
Many patrons tip based on how quickly their food is delivered, and if it is hot or not, how it tastes, did it meet the patrons' expectations or not for this specific type of food, what is the frequency of the patrons' dining on this specific type of Continue Reading...
The Type 1 error refers to rejecting the null hypothesis when it is true. The Type 2 error is when one rejects the alternative hypothesis even though it is true. 3. Parametric and non-parametric tests Parametric tests usually deal with samples tha Continue Reading...
statistical analyses used. List the statistical procedures used to describe the sample. Power analysis was used in order to discover power of effect. The power was set to 0.8 with a significant level of 0.05. Differences between the intervention a Continue Reading...
The fourth step is to perform the relevant statistical test and acquire a test statistic along with its p or probability value (Iyanaga & Kawada, 1980). The fifth and final step involves making a decision to reject or not reject the null hypothe Continue Reading...
An example of a business situation where the probability distribution may be utilized is a scenario where a manager attempts to predict employee retention. The statistical test would be a binary logistic regression analysis. The probability distrib Continue Reading...
Statistical Analysis Reported in Two Journal Articles Research endeavors, albeit it clinical, empirical, descriptive, historical, or case study oriented, must at all times adhere to the rigors of effective or best-fit research practice. Without str Continue Reading...
A more robust method is to conduct a factor analysis before running the regression analysis, and then to rotate the factors to insure that the factors are independent in the factor analysis ("Statistics Solutions, 2012"). 9. Discuss autocorrelation Continue Reading...
Statistical concepts have literally thousands of applications, but I will focus on those that apply to several major fields: political science, marketing, economics, social services, and insurance. Statistics are so key to the nature of these fields Continue Reading...
This analysis was deemed necessary as differences can exist on the basis of an overall group effect and not an individual variable (question) effect and visa versa. Male Mean Per Question Analysis x Department Source of Sum of d.f. Mean Variatio Continue Reading...
Their pricing approaches, while in the boundaries of solid statistical analysis, are somewhat opportunistic. For Zillow to be more accurate, the use of a range of valuations for each property could be included. This would be more realistic to the tr Continue Reading...
testing a hypothesis is to establish one. There should be a null hypothesis that the data can be used to test. Data acquisition is therefore the next step in testing the hypothesis. The data needs to relate directly to the hypothesis with a clear re Continue Reading...

The opposing side, which sports a more eclectic set of disciplinary backgrounds and prides itself on a more sophisticated and inclusive perspective, divides human abilities into broad classes -- logical, spatial, interpersonal, verbal, etc. -- and l Continue Reading...
normal distribution is used to find the probability of the sample mean in this single sample z-test (we know the standard deviation of the population). Z-scores are measures of relative location. Suppose we are interested in whether enrichment sessi Continue Reading...

Strategy Theory and Actual Strategies Being Used in Small Insurance Companies Ask any layman on the street what they think about insurance companies and the answer will invariably be negative. Consumers, by and large, view insurance companies with Continue Reading...
Standard deviation is a measure of how far the data is spread from the mean, and can be used to assess the accuracy of the sample mean. Type I errors are improper rejections of the null hypothesis. Type II errors are failures to reject the null h Continue Reading...
