16.Know the difference between mean, median, and mode. Know how inferential and descriptive statistics differ.a.Mean: average value b.Median: most frequent valuec.Mode: midpoint in a distribution d.Inferential statistics: makes inferences about populations using data drawn from the populatione.Descriptive statistics: brief descriptive coefficients that summarize a given data set whichcan be either a representation of the entire population or a sample of it 17.Be able to calculate a chi-square statistic and determine whether it reveals a statistical relationship between two variables. This will require that you perform the same proceduresthat we went over in class.18.In the data analysis lab (see the handout online), I described when to use four different statistical tests to determine if two variables are related to one another. When is a chi-square test the appropriate procedure? When is a bivariate regression appropriate? When is a t-test appropriate? [Hint: Answering this question requires that you consider whether the independent and dependent variables are nominal, ordinal, or interval/ratio in character.] #### You've reached the end of your free preview.
