Statistics Worksheet
Your research team has been tasked with finding the correlation of the following scenario: Four research participants take a test of manual dexterity (high scores mean better dexterity) and an anxiety test (high scores mean more anxiety). The scores are as follows: Person Dexterity Anxiety 1 1 10 2 1 8 3 2 4 4 4 -2 Describe the process your research team would go through by completing the following: Create a scatter diagram of the scores, which should be a negative direction. Describe in words the general pattern of correlation, if any. Figure the correlation coefficient. Explain the logic of what you have done, writing as if you are speaking to someone who has never heard of correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing). Provide three logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation in light of the variables involved. Explain why.

QMB4100 Rasmussen College Business Requirements & Key Business Questions
For your course project (use attached), you must submit a 3-4 page Word document that includes the following:Describe how your new product or service could potentially provide solutions for stakeholders.List at least 3 business requirements as they relate to your topic. This should help determine what you expect to measure.List at least 3 KPIs or key performance indicators.What kind of data would you need to know that could affect decision making processes?Based on your project topic, identify at least 5 key business questions. Key business questions should be what stakeholders would like answered by using business intelligence tools and technology.Along with each key business question, provide examples of a visualization that you might use to answer these questions.

MTH 218 UOPX Wk 4 Test Type Depends on The Population Sample Collected Response
Consider a situation that you might want to study through a statistical lens. The situation would require you to study a small sample and make an inference to the population. For example, you might want to understand how likely children are to complete their homework when considering their individual characteristics or maybe you want to understand if children who eat broccoli are more likely to complete their homework than those who do not.Respond to the following in a minimum of 100 words without any reference:How would you select a test that was appropriate to answer your question?How would you rule out tests that were not appropriate to answer your question? Post 2 replies to classmates or your faculty member. Be constructive and professional.This is one of the responses from another student that I need to reply to:"To determine the kind of test to use will depend on the population sample collected. For instance, we can use the T-Test to find the difference between the two pairs of the mean. In our case, we need to determine the individual characteristics which can be easily done using the ANOVA test. First, we need to find quality data sample population and compare those population means with three or more population mean. The main idea is to figure out how much of the total variance is from either the variance between the groups or the variance within the groups. Therefore, our Null hypothesis will be all the population mean of those groups is equal while the alternative hypothesis will be at least one mean of those groups is different. As illustrated below.H0: µ1=µ2=µ3Ha: At least one the mean differs from the others.For this case, we have to test how these means differ from other mean populations. We will use the concept of variance to test if our null hypothesis means is likely equal to other means for us to accept or reject if one of the means is not likely to be equal to other means. For better results, we need to study our population sampling as we use the concept of variance. Once we find the one or more mean differ, we have to validate the result because the quality of data affects the outcome, and also it will depend on our population sample."

If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? If we could, what other independent variables should be included in the analysis? What statistic(s) would show the value of that regression in understanding BMI?
Alternatively, find an article that uses regression analysis to study a medical concern. In that study, what was the dependent variable and what were the independent variable(s)? Further, how would you use this study to highlight the difference between correlations and causation?
