Kolmogorov–Smirnov test

Categorical data were summarized as percentages (%) or number (n). Comparison between groups was done using the unpaired t-test or Mann-Whitney test as appropriate. Comparison within each group (baseline versus after two months) was done using the Wilcoxon signed rank test. Chi-Square test or Fisher's exact test were used for categorical variables. Percent change was calculated as follows: [(current value – baseline value )/(baseline value)]x 100 Statistical significance

Chris Watt, Sarah Elmer, Kyle Luithly 1 May 2015 Pricing and Revenue Management Implementation of Pricing and Revenue Optimization Introduction Perhaps one of the most difficult managerial decisions in the 21st century is the decision to make a decision. Analysis paralysis, endless meetings, and corporate structure have made it painstakingly difficult to come to any real conclusions. So when the Chief Financial Officer, Bruce Berman, of Bloomindale’s was tasked with decision to implement ProfitLogic’s

levels (group and over-time).  Scale of measurement: The independent variable - intervention is a nominal scale of measurement and time is a ratio scale of measurement; the dependent variable is a ratio scale of measurement  Statistical test: Fisher 's exact test will be used for nominal scale. For

compared to a normal distribution H2 Family poverty is not skewed compared to a normal distribution The Chi-squared test has certain requirements in terms of the minimum expected population for each category. The data did not meet these criteria, meaning that the chi-squared test in this circumstance would be inappropriate. To avoid such issues, the nonparametric Kolmogorov-Smirnov test was used in preference as it has less rigorous data requirements.. The positive skewness values for FP89 (1.285)

Abstract Due to the rapid growth of broiler chickens, skeletal disorders have become a serious problem for the poultry industry. This, in turn, leads to an unwanted expense for poultry farmers and so they seek out a way to improve the bone strength and welfare of the birds. Silicon (Si) is an important element to the body as it can improve bones and the immune system. This means it can be used in diets as a cheaper alternative to calcium and phosphorous. However, there is little understanding of

analyzed using the statistic packaged as follow: 1. Descriptive analysis was used to describe the demographic data and depression score. 2. Chi-square test and independent t-test were conducted to examine the differences of demographic data between the participants in the experimental group and control group at the baseline. Independent t-test was used to compare depression scores between the experimental group and control group at the baseline. 3. The Two-way Repeated-Measures ANOVA was used

An Empirical Analysis on The Weak-Form Efficiency of The GCC Markets Applying Selected Statistical Tests Rengasamy Elango, Mohammed Ibrahim Hussein This paper tests for market efficiency across the seven stock markets in the GCC (Gulf Co-operation Council) countries.

Ocular Surface Disease Index (OSDI) The OSDI questionnaire was used to quantify the dry eye symptoms before surgery and 2 weeks, 1 month and 3 months postoperatively. In this questionnaire, patients were asked about dry eye symptoms that they had experienced during a 1-week recall period. Each answer was scored on a 4-point scale from zero (indicating no problems) to four (indicating a significant problem). Accordingly, we combined the responses to all of the questions to generate a composite

measured the ceiling effects of the Lysholm score and the IKDC subjective score when utilized for evaluating functional outcomes post-ACL reconstruction and compared their concurrent validity by assessing the correlation of each score with a one-leg hop test. This was a retrospective study, consisting of 134 participants who underwent an ACL reconstruction between May 2007 and April 2011. The authors of this study set up the inclusion criteria as an ACL rupture with or without a meniscus tear and participation

after weight lifting and running. The weights used was one 8 lbs dumbbell and the running was done on the treadmill. Once all the data was gathered from the eight participants, the results were analyzed with a specific statistical test called Paired T- Test. Paired T-Test is obtained from SPSS, a statistical software used to evaluate the results. Heart Rate and/or beats per minute evaluation: The participants were taken to a gym where they had access to a treadmill and dumbbell.  The procedure of
