1.Toaccurately and correctly run a regression analysis, the data MUST be:

A.nominal and ordinal

B.linear and continuous

Clogarithmic and qualitative

D.log-linear and discrete

2.In essence, what does linear regression do?

A.it transforms the data from linear to exponential

B.it adjusts the slope so that it is always positive

C.it calculates the standard deviations of all errors; and the sum of the standard deviations describes the strength of the relationship

D.it fits a line [of best fit] to the data in a scatter diagram

3.In a correlation analysis, you calculate an R value of -0.006. You run a significance test and find that this result is not significant. Which of the following BEST describes the relationship between the two variables?

A.there is a weak, negative relationship between the variables

B.there is a logarithmic relationship between the variables

C.there is a strong, negative relationship between the variables

D.there is basically no relationship between the variables

4.Which of the following tells us the proportion of variance in Y that is explained by the independent variable in a bivariate regression analysis?

A.Spearman coefficient

B.critical r value

C.coefficient of determination

D.standard error

E.y-intercept

5.Which of the following does NOT use interval/ratio level data? (You can use the example of rainfall totals or wind speeds for data type)

A.two sample t-test

B.Pearson correlation

C.regression analysis

D.Spearman correlation

6.Which of the following is True regarding correlation?

A.correlation only proves causation when r is close to zero

B.correlation only proves causation when r is close to 1

C.correlation only proves causation when there is a negative slope to the scatter plot

D.correlation does not prove causation

7.Your critical F-value is 2.95.Your within group variance is 10.4.Your between group variance is 17.9.Do you accept or reject the null hypothesis?

A.With a calculated F value of 1.72--you do NOT reject the null

B.With a calculated value of 1.72 you DO reject the null

C.With a calculated value of .58, you do NOT reject the null

D.You need to know the degrees of freedom before deciding.
