statistical analyst because I love statistics. Furthermore, I am very organized which I believe is an important skill in every position, . I took AP Statistics last year, so I understand all the computations that need to be made, and I have all the necessary software to create graphs and other visual aids. Because I have taken statistics, I understand how to make more advanced calculations, so I believe that I am best suited for this position. When I took AP Statistics, it was my best class, and it is
This discrepancy may increase the risk of type I or type II errors that may have an impact on public health as well as may cause economic loss due to the estimated 24 hour delay in reporting results. A type I error is the incorrect rejection of a true null hypothesis or in other words, it leads one to believe that a supposed effect or relationship exists when, in fact, it doesn’t (Banerjee et al., 2009). An example of this in terms of water quality monitoring is prohibiting swimming unnecessarily
Empirical Validity Empirical or predictive validity is the extent to which scores on one assessment correspond to the same behaviors measured with other assessment instruments. For an assessment to be empirically valid, statistical evidence must suggest the instrument measures what it is meant to measure (Trochim, 2006). The BDI-FastScreen was correlated with two other assessment instruments that measure symptoms of depression and with the diagnostic criteria for depression in the Diagnostic and

The testing of relationships between two variables is involved in correlation as a measure of association. There is a main point for the test which is, based on the strengths of the association and the direction as well. According to my readings from Leedy and Ormond, (2010) a correlation can exist when a variable increases and another variable decreases or increases in a sort of known way. The test using correlation as a measure of association summary, can help be determined by the similarities
I have chosen to report to 4 significant figures for this assignment as going to two decimal places would have disrupted values such as the p–value for the t-test (0.0002720). TWO SAMPLE (UNPAIRED) T-TEST WITH UNEQUAL VARIANCES ANALYSIS The null hypothesis for this experiment was; H0: μ1=μ2. Therefore the alternate hypothesis was; H1: μ1≠ μ2. The test used to determine if we can fail to reject the null hypothesis is a two sample (unpaired) t-test with unequal variances. A two sample test was chosen
Assignment 1 1. For this experiment, I have gathered results from five participants. The participants are family members that are currently visiting. The average age of participants for this experiment is thirty five. I made two lists on two different pages on blank printer paper. On the Trigram and Word condition list is written ten random letters that are centered and descend equally spaced down the page. I have decided to use the same order of the lists for each participant, which is the Trigram
1. How did you select this research study to analyze? That is, what search terms did you use? What database did you use? What was your rationale for selecting this particular study to analyze over the others identified in the search results? What is the full reference for the study in APA format? When searching for research studies about Academic Clustering I used the SportDiscus through the University of North Florida’s Database. Using the terms Athletes and Academic Clustering. I chose this article
