Refer to the exhibit:

The box plot was used to analyze daily sales data following three different ad campaigns.

The business analyst concludes that one of the assumptions of ANOVA was violated.

Which assumption has been violated and why?

A.

Normality, because Prob > F < .0001.

B.

Normality, because the interquartile ranges are different in different ad campaigns.

C.

Constant variance, because Prob > F < .0001.

D.

Constant variance, because the interquartile ranges are different in different ad campaigns.

Calculate the accuracy and error rate (0 - negative outcome, 1 - positive outcome)

A.

Accuracy = 58/102, Error Rate = 23/48

B.

Accuracy = 83/102, Error Rate = 67/102

C.

Accuracy = 25/150, Error Rate = 44/150

D.

Accuracy = 83/150, Error Rate = 67/150

Refer to the lift chart:

At a depth of 0.1, Lift = 3.14. What does this mean?

A.

Selecting the top 10% of the population scored by the model should result in 3.14 times more events than a random draw of 10%.

B.

Selecting the observations with a response probability of at least 10% should result in 3.14 times more events than a random draw of 10%.

C.

Selecting the top 10% of the population scored by the model should result in 3.14 times greater accuracy than a random draw of 10%.

D.

Selecting the observations with a response probability of at least 10% should result in 3.14 times greater accuracy than a random draw of 10%.

Refer to the lift chart:

What does the reference line at lift = 1 corresponds to?

A.

The predicted lift for the best 50% of validation data cases

B.

The predicted lift if the entire population is scored as event cases

C.

The predicted lift if none of the population are scored as event cases

D.

The predicted lift if 50% of the population are randomly scored as event cases

Which of the following describes a concordant pair of observations in the LOGISTIC procedure?

A.

An observation with the event has an equal probability as another observation with the event.

B.

An observation with the event has a lower predicted probability than the observation without the event.

C.

An observation with the event has an equal predicted probability as the observation without the event.

D.

An observation with the event has a higher predicted probability than the observation without the event
