- Which of the following kinds of data should be analyzed with Parametric procedures? Group of answer choices Interval Ordinal any kind of data NominalNonparametric tests should not be used whenWhat statistical test would be most appropriate if you were interested in seeing how religiosity changes in early adulthood? Religiosity was measured using an interval scale, and the same participants provided data at two time points – at age 15 and 25. Assume the data meets all assumptions for a parametric test
- Disadvantages of non-parametric tests include: a.For hypothesis testing not estimating effect size b.Degree of confidence may be too high c.May lack power (compared to parametric tests) d.A & CHow can I tell if the Mean value theorem can be applied or not?What is a name for the curve that has the mean, median and mode at the center? Mesokurtic Platykurtic Gaussian
- Identify the (a) appropriate non-parametric procedure for each item and (b) provide a short justification why the test is appropriate. The cafeteria regularly asked customers to rate the speed of their service. Suppose 15 customers were surveyed and their responses (1-Poor; 2-Good; 3-Very Good; and 4-Excellent) were recorded. From the data collected, the cafeteria owners wish to infer that the general rating of the customers is not poor.Can the Mean value theorem be applied ? What is the value of C?Please answer both multiple choice questions. a.) An investigator is predicting systolic blood pressure by minutes of moderate exercise. If the regression line is Y = 130 – 0.5* X. What will be the difference of systolic blood pressure for a person that did 30 minutes of moderate exercise and a person that did 40 minutes of moderate exercise? 115 10 120 5 b.) According to the picture attached of the resdiual plot, pelase select the statement that is true. All the assumptions are met. There is problem of heteroscedasticity. There is problem of collinearity. We should include higher order terms.
