MEDSCI 725: EXPERIMENTAL DESIGN Ellynn Sy ANCOVA and More Complex Designs (Parametric Tests) Introduction Analysis of covariance (ANCOVA) is most frequently used to refer to the statistical technique that combines regression and ANOVA [1]. It offers a way to obtain a more precise assessment of the effect of the experimental manipulations on the dependent variable. An ANCOVA design requires the measurement of one or more other variables. These variables are covariates, predictor, variables,…
Almost losing my life when I was very young, at a time where the experience would last with me forever, has taught me several things about human existence. When I was young I was a simple little girl with cute hair and big blue eyes and when my mother lost her job in Florida we had to live with my aunt and her kids in Vermont. On Saturday, November 22, 2003, in my aunt’s garage, I was attacked by an animal that had fractured my skull, ripped off my right ear, and all of my hair. This experience…
driving, etc. In, this experiment our main objective was to figure out what would happen if we alter one of the value. Since both are dependent on each other we alter the vision of the subject and see how accurate the subject’s throws are based on their normal and impaired vision. We know that impairing a person’s vison would affect the accuracy but not accurately though. This experiment was conducted prove it using the scientific method. But, we were also able to answer certain questions like…
and it ends up messing up your blood and body. There were so many things to learn and account for in just a little amount of time. I learned that when my brother came to the hospital his glucose levels were at 306 Mg/DL which is crazy because the normal person wants to be 70-120 Mg/DL. However, once he started taking insulin his levels were all over. One day he was at 416 Mg/DL before and dropped to only 30 Mg/DL in the night. Having too many highs affects your long term health greatly, while…
temperature of the water. During the process of this experiment because of my lack of access to a thermometer for the hot water (100 C) I used boiling water, which made sense. However, for the other 2, the medium water temperature (50 C) I used water from a normal aqua bottle that was just delivered and a little bit heated up. For the cold water (25 C) I just put an aqua bottle in the refrigerator for 10 minutes. This was inaccurate and unfair. If I was given another chance to perform this…
• PSO Algorithm to generate test cases A. Initialize the population with N Particles where Program will search for optimal solution through the movement of these particles. And Set iterations counter I = 0. B. Apply Fitness function: Calculating the fitness value by calculating the percentage of this particle will share in minimizing the total processing time to find the optimal solution. C. Compare the calculated fitness value of each particle with its (lbest). If current value is better…

2-8- Statistical analysis Results are presented as mean±standard deviation (SD) of two replicated determinations. Data were subjected to one-way analysis of variance (ANOVA) and multiple comparisons were performed by Duncan's test. Statistical significance was set at P>0.05. All analyses were performed using SAS version 9.1 (PROC GLIMMIX; SAS Institute Inc., Cary, NC). 3. Results and discussion 3-1- physicochemical changes of grape juice contain encapsulated probiotics 3-1-1- pH According to…
Imprecision The lowest coefficients of variation for precision within and between series over the whole tested concentration range were found for the LIAISON CLIA and LC-MS/MS method. Then followed the RIA. The Immulite CLIA showed the highest overall values and thus the lowest precision. A detailed list of all calculated variation coefficients is provided in Table 1 (A). Sensitivity The limit of blank (LoB), limit of detection (LoD) and limit of quantification (LoQ) were determined for all…
