: ''' | : '''SQ6.''' Be ready to explain Table 3. In particular, be ready to talk about the bivariate relationships between "Final score" all of the other variables in the model. Be ready to talk about the correlation both in quantitative and in substantive terms. | ||
: ''' | : '''SQ7.''' Do you think that the assumptions that underly the linear regression model reported in Table 5 hold? What information might you like to have seen provided to help you determine your answer? | ||
: ''' | : '''SQ8.''' Be ready to explain what Table 5 means in both statistical and substantive terms. In particular, be ready to interpret the coefficients in substantive terms and be ready to explain what the t-statistics, <math>R^2</math>, and p-values mean. Be ready to provide a sentence for each that interprets each number in the table in substantive terms. This will mean understanding what every variable actually measures. |
