answer only those questions they are comfortable answering * Encourage each participant to provide accurate responses A large department store examined a sample of the 18 credit card sales and recorded the amounts charged for each of three types of credit cards: MasterCard, Visa, and Discover. Six MasterCard sales, seven Visa, and five Discover sales were recorded. The store used an ANOVA to test if the mean sales for each credit card were equal. What are the degrees of freedom for the F…

would prefer to use this type of quantitative risk analysis method, because it provides measurable and interchangeable description of the potential risks; also, it provides alternative options for stakeholders to compare. If my project team have to deal with a project which puts the cost at the top priority of the triple constrains, I would definitely use the EMV analysis to give my sponsors and other stakeholders a clear and valid risk analysis report. Finally, the third type of quantitative…

Figure 3 shows the voter turnout in the dataset years as the lines are representation of the countries Figure 4 shows an easier explanation of average of voter turnout for the countries in the dataset. This shows the overall to give the average turnout because figure 4 gives an understanding of this. The countries that have higher turnout are more of List PR and the lower ones are FPTP. An interesting outcome of this looking at the Scandinavian countries all have mostly higher turnout comparing…

first factor discussed was the discovery that computations can be utilized to measure observational error, by and astronomer, Lambert Adolphe Quetelet. This discovery led to the development of the normal distribution curve utilized today (Cowles & Davis, 2016). Following the development of the normal distribution curve, a measure of variability known as probable error was discovered (Cowles & Davis, 2016). This discovery was the second factor mentioned by Cowles and Davis (2016) that…

grades. We create grade averages and class ranks based on those averages. We use these averages to select valedictorians and award honors.” This level of measurement is impartial and should not be used in calculations, but we continue to use this type of data to classify students inadequately. The interval level of measurement provides more concrete data analysis. Values are created based on data that can be ordered and have a distinct difference between each level, hence the term interval…

jobs that fit in the social category. He found Rehabilitation Counselor, and Academic Advisor. Those are two different carriers that Sean has considered perusing so it seems to fit him. The last assessment that Sean took was the NEO-FFI-3. It is a type of personality assessment Sean enjoyed taking the assessment. He found the results to be fairly accurate and he felt like it was worth his time. Overall he enjoyed taking the assessment and found them to be really helpful and that he agreed with…

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…

indicators are used to form a superordinate construct where the individual indicators are weighted according to their relative importance in forming the construct (Chin, 1998). Moreover, the normality of data distribution not assumed, thus data with non-normal distributions can be conducted in structural equation modeling since its application is performed in a non parametric way. PLS is also recommended when either cross-sectional, survey, or quasi-experimental research designs are used; when a…

There are different types of parametric tests to determine if a statistically significant difference is present. An independent-samples t-test is used when comparing two groups on one continuous dependent variable that is normally distributed. A paired-samples t-test is used when you look at the differences of one group across two time periods or observation periods. ANOVA tests are used when we are examining more than two groups or more than two observation periods. Slide 3: Our null…

expressed as the equation SEM=S_E=√(S_X^2 (1-r_(XX^ ' )))=S_X √(1-r_(XX^ ' ) ). If the test reliability is 0, SEM would be equal to the standard deviation of the observed scores; if the tess reliability is 1, SEM would be 0. In addition, different types of reliability coefficient used to calculate SEM could provide different SEM…
