Correlation and Regression We'll be using the parenthood dataset in jamovi to practice with these statistical models. So, open the dataset and make a quick review of the variables. Correlation - walk through Test the research hypothesis that the more the baby sleeps the less grump Dan is. Data Analysis: 1. Considering the RH: -- Does this research hypothesis suggest a positive, a negative, or no relationship between these variables? Explain. 2. Examining the Scatterplot -- get the scatterplot of these variables Is the relationship clearly nonlinear? What would we do (or not do) if there was a nonlinear relationship? Does the "direction" of the scatterplot seem to support the RH:? Why or why not? 3. Statistical analysis -- get the Pearson's correlation of baby.sleep and dan.grump For the hours baby slept mean = std = For Dan's grumpiness mean = std = N = df = r = p = State the H0: Retain or reject H0: Support research hypothesis ? 4. Write-up with univariate stats
