Assignment: Variables, Measurement, and SPSS
Assignment: Variables, Measurement, and SPSSQuantitative research consists of testing and understanding relationships between variables. Researchers construct these variables as measureable expressions of social phenomena. Modern statistics provides you with a host of resources to answer questions, but each statistical test has a set of assumptions regarding the measurement of the variables. It is therefore important to understand how variables are measured because their measurement will influence the type of analytic tools available to you.SPSS is a statistical software program that allows you to enter these variables into a spreadsheet format and record the measurements from a sample. Additionally, SPSS allows you to perform statistical analysis. Before launching into your analyses, though, it is important to understand how the variables are measured. That understanding will help you interpret the SPSS output.In this week’s Discussion, you considered topics with social change implications. For this Assignment, you will examine data to analyze independent and dependent variables, determine how they are measured, and decipher whether a social change question can be answered and the implications for such change.To prepare for this Assignment:Review the Learning Resources as well as the SPSS resources found in this week’s Learning Resources.Review, download, and install the SPSS software on your computer using the IBM SPSS Version 23 Installation and Registration document for PC or for MAC in this week’s Learning Resources.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in this week’s Learning Resources and then choose two variables that interest you.For this Assignment:Write a 1- to 2-page summary and include the following:A description of what the each of the variables measure.A description of the unit of analysis.A description and explanation of the levels of measurement for each variable (i.e., nominal, ordinal, interval, ratio).Explain how you might conceive these variables to be used to answer a social change question. What might be the implications for social change?Support your summary using appropriate scholarly citations and references. Use proper APA format.By Day 7Submit your Assignment 1: Variables, Measurement, and SPSS.

PUBH 8500 Walden Assumptions of Linearity Sampling independence Normality & Homoscedasticity Paper
Assignment: AssessmentThe testing of assumptions, recognition of limitations, and proper use of diagnostics are all necessary elements in the use of multiple linear regression for public health research. All of these elements allow biostatisticians to better assess the results of multiple linear regression models.For this Assignment, you test that assumptions for multiple linear regression have been met, use SPSS to create a multiple linear regression, evaluate results to determine whether the model is appropriate, and finally interpret the relationships uncovered through this statistical test between the independent and dependent variables. Use the Week 4 Dataset (SPSS document) from the Learning Resources area to complete this assignment.The AssignmentExplain the assumptions of Linearity, Sampling independence, Normality, and Homoscedasticity (or equal variance). (30 points)How would you test whether these have been met? (Note: for the exam you do not need to test these assumptions)Using SPSS, test the assumption of Linearity between the independent and dependent variables.Using SPSS, test the assumption of Normality for the dependent variable.Conduct a multiple linear regression using SPSS. Provide relevant SPSS output and assess the statistical significance of the effects of mother’s Age, BMI, and Coffee (Cups per Day) on Birth weight. (30 points)Explain the practical implications of your finding. Include a reference to the R square of the model in your discussion. (20 points)Discuss whether or not there is interaction (effect modification) first between Age and BMI and second between BMI and Coffee. (20 points)

"Confidence Interval"
Note: Online students, please select one of the two subjects to discuss.Use the Internet or Strayer Library (https://research.strayer.edu) to research articles on confidence interval and its application in business. Select one (1) company or organization which utilized confidence interval technique to measure its performance parameters (e.g., mean, variance, mean differences between two processes, etc.). Give your opinion as to whether or not the utilization of such a technique improves business process for the company or organization that you selected. Justify your response.Select one (1) project from your working or educational environment in which you would use the confidence interval technique for the process. Next, speculate on one to two (1-2) challenges of utilizing such a technique in the process and suggest your strategy to mitigate the challenges in question. Please respond to peer posting: In a given distribution confidence intervals is the probability that a parameter will fall between the upper and lower bounds. The intervals are used to know uncertainties in predictions hence a business can measure its performance (Hoerl & Snee, 2012). When manufacturing iPods, Apple has applied the technique to predict the performance of this process. To determine the reliability of iPods and the effectiveness of the production process used, the company utilized confidence intervals. Using 200 employees as sample population, they tested the dependability of the devices and only two of the devices broke down in a span of one month.Their aim was to determine how many of the iPods would break if they were released to the public at the time of the first production. In an unknown population p, 2/200 is equal to the confidence interval of the population and the proportion chosen (about 1% of p) calculated this interval. With a 95% confidence interval, the company was secure to sell the devices. Nolan, Mitchell and Doyle-Baker 2014 note that the high percentage was a clear indication of the relationship of the breakage in the public. It is challenging for a company to determine the success of its products in the market. Therefore, this technique helps to determine the unknown factor which can help organizations make decisions on their products and operations.ReferencesHoerl, R. & Snee, R. D. (2012).
