Probability distribution

researchers, and politicians. The gap between the top 1% and the other 99% of Americans has increased for the past three decades (DeSilver; Cobb; Milanovic; Hatch, Ribgy; Jacobs, Dirlam; Cooper, Palumbo, Lutz). Income inequality is defined as the uneven distribution of income in the population, and the gap between the wealthy and everyone else (Priester, Mendelson). In 2013, the top 1 percent of the population took home more than 20% of income earned (Saez, Piketty). Bill Gates and Warren…

The system in which our upbringings are bred to abide by is the very thing that is allocating our lives without many of us even realising. Our consuming and contented nature produces a physically unsustainable earth and we nourish the current system which is morally unsustainable, an ecological imbalance is imminent. This report proposes to deconstruct these occurrences that lead to a world not savvy of their own environmental irrationalities. Focusing on the calculations that formulate…

Through reviewing the minimum, maximum, and range of values I attempted to discern and identify potential coding errors as well as invalid data. The nature and distribution of the values were explored through examining the mean, standard deviation, and variance as well as skewness and kurtosis. For example, the variable Age contained 320 valid cases, with respondents ranging in age from 18 to 35 years. The mean age…

This signifies that there is a moderate variation in data, skewed towards younger age group. Further, an appropriate graph for ADULTCT, measured at ratio level, is a histogram which can help us understand the shape of the distribution. The histogram displays that the number of adults in the household is positively skewed, as significant amount of data lies at the lower end of the graph. This signifies that majority of the respondents have two to three adults in the household…

Trying to document my performance while doing the job proved to be difficult at times. In the second week, I was stressed at trying to get both done. My boss told me to just do my best and gave me some tips on how I could be more efficient. My motivation was low since my opportunity to perform was limited with all the work I was trying to do. In the fourth week, my boss told me that my performance was much better and that I had made far fewer errors. I still needed to work on understanding…

Repeated Measures Analysis of Variance (RM-ANOVA) was conducted to compare the reaction time of visual and acoustic conditions (previously shown in study phase) with new brands (not presented before)(Graph 1). Mauchly’s test showed that the assumption of sphericity had not been violated, χ2 (2) = 0.68, p = .711. Degrees of freedom were corrected using Greenhouse-Geisser estimates of sphericity ( = .98). There was a significant effect of modality type, F (2, 60) = 20.09, p < .001. Bonferroni…

Computations and Interpretation Mean = 7.02. After analyzing the scores of my population, I found that the mean average was 7.02 out of 10. This implies that the average student earned a “C” or 70% in the quiz. If I remove the outlier that consists of 0 out of 10 I believe that the average score would increase to a more meaningful average score. Median = 7. The median depicts how the center of all scores achieved was a “C”. The median may be a score or average of two, that is the farthest…

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…

The Effect on Hand-Eye coordination while Impairing Vision. We found that disrupting a person’s vision could affect the subject’s hand-eye coordination. It would have negative effects towards hand-eye coordination. Drunk googles were used for this experiment and we it affected the subject’s vision as it limits their ability to see properly. A bean-bag was asked to throw to the specific area by the subject with and without wearing drunk googles. The subject had better hand-eye coordination…
