Please find a REGRESSION ANALYSIS for this… 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 […]

To Set the Criteria for the Decision (step 2 in hypothesis testing) we must identify the critical value and the rejection region. What information do you need to set the criteria? How do you determine when to use a one-tailed test? When do you use a two-tailed test?

A population distribution is standardized to produce a new distribution. What is the standardized distribution called? What information is provided by the sign (+/-) of a z-score? What information is provided by the numerical value of the z-score?

You and a friend are talking about the probability of getting a heads on a single toss of a fair coin. Your friend insists that you are more likely to get a heads on a single toss of a fair coin than a tails. Is your friend correct, why or why not? If we were to toss the fair coin an infinite number of times, […]

Use the attached document, “Project 2-Articles,” and the following articles to complete this project: “Effects of Cognitive Behavioral Group Program for Mental Health Promotion of University Students,” by Lee & Lee, from International Journal of Environmental Research and Public Health (2020). “The Stigma Scale: A Canadian Perspective,” by Meier et al., from Social Work Research (2015).

What is a post-hoc test and why it is necessary when rejecting the hypothesis with an analysis of variance (ANOVA) statistical test? Describe what a post hoc test detects. Explain an experiment in which you as a researcher would run a post hoc test. Why?

The first problem we confront in analyzing data is determining the appropriate statistical test. Under what circumstances is a t statistic used instead of a z-score in a hypothesis test? Give an example of both a t statistic and z-score.

Explain what is measured by each of the following: sum of squares (SS), variance, and standard deviation. Why is it essential to understand the difference between sample statistics and population parameters (e.g., when to use n-1 when calculating variance)?

My hypothesis test is whether using a pain reliever, Pyridium (phenazopyridine), before a in office cystoscopy decreases the burning/pain sensation after the procedure.   A cystoscopy is where a telescope is inserted through the urethra into the bladder.  We do this procedure for many reasons including blood in the urine, bladder cancer surveillance and recurrent urinary tract infections.   Two types of hypotheses are the hypothesis and […]

The Lazer Company has a contract to produce a part for Boeing Corporation that must have an average diameter of 6 inches and a standard deviation of 0.10 inch. The Lazer Company has developed a process that will meet the specifications with respect to the standard deviation, but it is still trying to meet the mean specifications. A test run (considered a random sample) of […]

In this course, you learned core applications of statistical analysis to solve real-world personal or professional inquiry problems. You also learned different techniques to draw conclusions from data. These experiences allowed you to practice designing an approach to a statistical problem, considering assumptions and constraints, and developing interpretations and conclusions. Think about how you felt when you first started the course and how you feel […]
