ASSIGNMENT Initially present your descriptive statistics (means and standard deviations)– these are usually presented in table format If you are using them as variables… you need to present gender and parents divorced as frequencies (because they are categorical variables) Also describe your table e.g., most participants reported a warm parenting style, followed by a perceived […]
What was your main research question (what were you trying to find out)? Why do you want to study this/Why does this interest you?
Research & Summaries: Survey Research Project (Research Methods) QUESTION 1 Answer the following questions: What was your main research question (what were you trying to find out)? Why do you want to study this/Why does this interest you? What is your dependent variable? What is your independent variable? What is your hypothesis based on these […]
Comparing the two equations, which model has estimated signs corresponding to your prior expectations? Can one argue that model 2 is preferred on the basis of fit?
ASSIGNMENT Consider the following two least-squares estimates of the relationship between interest rates and the federal budget deficit in the United States: Model 1: N = 56, R2 = 0.00 where: = Interest rate on AAA corporate bonds = Federal budget deficit as percentage of GNP Model 2: .369 N = 38, R2 = […]
Using the given data for a sample of 30 inmates of the Polk County Jail. Perform a t-Test for the regression slope of the data to determine if the data fits a linear model using alpha = 0.05.
ASSIGNMENT For this assignment you will be using the given data for a sample of 30 inmates of the Polk County Jail. 1. Use a Simple Linear Regression to find the regression equation that predicts weight (lbs) from height (inches). Note, “weight” will be the dependent variable (y) and “height” will be the independent variable […]
In a bivariate regression, which variable is the dependent variable and which one is the independent variable? What does the intercept of a regression tell?
Week 4 Discussion Regression analysis is a powerful and commonly used tool in business research. One important step in regression is to determine the dependent and independent variable(s). In a bivariate regression, which variable is the dependent variable and which one is the independent variable? What does the intercept of a regression tell? What does […]

Does this paper describe a randomized clinical control study or an epidemiological study? Identify at least one pro and one con of that type of study. 3. What is the sample size […]
What are some of the drawbacks to pet ownership that may detract from potential benefits to health?
Have you ever, or do you currently own a pet? Many pet owners are very fond of their furry (or crawly, or slithery) friends, however, do they help decrease our stress levels? In the past 10-15 years, scientists have been pursuing research on that very question. We won’t specifically focus on the topic of stress […]
Interpret the Shapiro-Wilk test and how you determined whether the assumption of normality was met or violated.
Step 1: Write Section 1 of the DAA: The Data Analysis Plan • Name the variables used in this analysis and whether they are categorical or continuous. • State a research question, null hypothesis, and alternate hypothesis for the analysis of variance (ANOVA). Step 2: Write Section 2 of the DAA: Testing Assumptions Test for […]
