Because a warranty imposes a duty on the seller, a breach of warranty is a breach of the seller’s promise.

Intellectual property is property resulting from intellectual, creative processes.

In class we retrieved data from the Web. From an academic study perspective, what kind of data is data retrieved from the Web?

Fill in the blank in the following statement: “When we discussed the need for an Institutional Review Board (IRB) for human interaction studies at UF, we reviewed some of the history behind the development of this oversight requirement. A particularly egregious study that is frequently pointed to as the reason that such oversight is required was the ________________________.” 

Is the following statement True or False? “In the evaluation phase of the CRISP-DM model, it is possible that the data science team will have to go back and restart the project from the beginning.”

You have been discussing the Republican ratio and its connection with the COVID-19 fatality ratio. You reran the regression with just the Republican Ratio (Rratio) as the independent variable and the COVID-19 case fatality ratio as the dependent variable. This simple linear regression model looks statistically significant. However, you remember to check the assumptions. One assumption you test is assumption of constant variance of the residuals.  You plot the residuals against the predicted Y values and see the following output. Do the residuals reflect constant variance across the predicted Y values?  

Your colleague is trying to determine if the Test-Retest of Question 1 indicates that the survey item demonstrates stability. Your colleague shows you the following output from SPSS. Is this the correct statistical test output to determine the stability of the Test-Retest for this question?  

You are performing an analysis for your research and you are checking the relationships between variables. In one step, you analyze the relationship between the dependent and independent variables. To do so, you look at this plot. Does it appear that these 2 variables are linearly related?  

Your colleague is using Multiple Linear Regression (MLR) to conduct their research. The colleague is trying to test to ensure that they have met all of the assumptions expected when conducting a MLR analysis. The colleague shows you the following chart. What regression assumption is being tested with this plot?  

Fill in the blank in the following statement: “As a doctoral student at UF, to conduct a human interaction study and complete your Institutional Review Board submission for approval, you must have a _______________________________.”
