Week 3 DQ 2

Why is it said that hypothesis testing involves double negative logic?

Hypothesis testing involves a double negative logic. We will never accept the null hypothesis.

Either we reject the null hypothesis or we do not reject the null hypothesis. The hypothesis

can be considered as a test against the null hypothesis. The data is evidence against the mean

and you can assume the mean is true and try to prove that it is not true. After finding the test

statistic and p-value, if the p-value is less than or equal to the significance level of the test we

reject the null and conclude the alternate hypothesis is true. If the p-value is greater than the

significance level then we fail to reject the null hypothesis and conclude it is credible. Note

that we cannot conclude the null hypothesis is true, just that it is credible.

Methods, data collection, and analysis

For this assignment, you reflect on the research question chosen for your Capstone Project “What impact do Extreme Risk Protection Orders have on public safety?” and how it influences the types of data that might help answer your question, as well as the research methods that would support collecting this type of data. The assignment must be 1 page and include: An explanation of the types of data that may help you answer your research question. Then, explain which research method might be best if you were to collect data for your Capstone Project and why. Support your explanation with resources from your literature review (WILL BE PROVIDED FOR REFERENCE) that discuss various research methods and analysis.

SPSS Data File Questions

SPSS Assignment 3An investigator is interested in predicting scores for a measure of cognitive function from the number of hours of sleep a person gets on average. She obtains scores for both the number of hours of sleep and cognitive function from 12 people. Higher scores for cognitive function reflect higher levels of performance. Hours of Cognitive Sleep Function ------------ ------------ 8.1 100 5.4 79 6.1 72 7.4 62 9.0 122 8.5 89 6.4 76 9.4 131 8.7 110 7.6 92 9.3 101 9.2 115 ------------------------------First, create an SPSS data file with the data above.Use SPSS as needed to complete the following:Write and submit the null and alternative hypotheses for the relationship between sleep and cognitive functioning.Compute r. Submit the value of the correlation coefficient between the number of hours of sleep and scores on the measure of cognitive function. Is the correlation coefficient significantly different from zero at alpha .05? What is the significance level (p-value) for this test? What conclusion should the investigator draw on the basis of this test with regard to the null hypothesis?What is the regression equation used to obtain predicted scores for cognitive function from the number of hours of sleep? Using the regression equation, what will the predicted score for cognitive function be if a person reports that they get 6.7 hours of sleep? What is the standardized regression coefficients?What percentage of variance in cognitive function is accounted for by amount of sleep account? What is the value for the standard error of estimate?Use SPSS to create a scatterplot with the number of hours of sleep on the X-axis and scores for cognitive function on the Y-axis. Please have SPSS display the regression line within this scatterplot.Submit your answers to #1-11 in a Word document. Please upload your file to Blackboard using the Attach File option.

Describe a conflict within an organization or team with which you are familia,, management assignment help

We live in a very complex and culturally diverse society. When we bring individuals together from diverse backgrounds in a work environment conflict can arise when expectations are not realized or met. Rather than hoping conflict will go away, this paper will explore and identify the reasons for conflict and how to successfully address them in a team environment. Write a four- to five-page paper (excluding title and reference pages) assessing the components of conflict. The following need to be addressed within your paper: Describe a conflict within an organization or team with which you are familiar. Identify and describe the source(s) and level of the conflict and support with evidence. Describe the steps taken to resolve the conflict or, if it is an ongoing conflict, propose steps to resolve the conflict. Describe a minimum of three conflict outcomes that could reasonably occur as a result of the conflict resolution. Support your reasoning for each possible outcome. Your paper must use a minimum of three scholarly sources, in addition to the textbook, your paper must be formatted according to APA style.
