Exam 17: Business Analytics

SCENARIO 17-3 The tree diagram below shows the results of the classification tree model that has been constructed to predict the probability of a cable company's customers who will switch ("Yes" or "No")into its bundled program offering based on the price ($30, $40, $50, $60)and whether the customer spends more than 5 hours a day watching TV ("Yes" or "No")using the data set of 100 customers collected from a survey. -True or False: Referring to Scenario 17-3, the highest probability of switching is predicted to occur among customers who do not watch more than 5 hours of TV a day and are offered the bundled price of lower than $50.

True or False: Single linkage can be used to measure the distance between objects in cluster analysis.

True or False: The forward-and-backward computation among the three layers of a multilayer perceptron is repeated until the output layer detects that the difference between the predicted results and the target values has been minimized or is at an acceptable level.

True or False: You can compute any of the numerical descriptive statistics for the variables of the new worksheet that a drill-down in a PivotTable creates.

True or False: In a regression tree, the dependent variable is a categorical variable.

True or False: In metric multidimensional scaling, the distance between objects is ratio scaled.

True or False: Neural networks use the validating data to uncover a model and then the training data to see if the model can make the correct prediction or classification.

SCENARIO 17-3 The tree diagram below shows the results of the classification tree model that has been constructed to predict the probability of a cable company's customers who will switch ("Yes" or "No")into its bundled program offering based on the price ($30, $40, $50, $60)and whether the customer spends more than 5 hours a day watching TV ("Yes" or "No")using the data set of 100 customers collected from a survey. -True or False: Referring to Scenario 17-3, the highest probability of switching is predicted to occur among customers who watch more than 5 hours of TV a day and are offered the bundled price of higher than $40.

True or False: Euclidean distance can be used to measure the distance between objects in cluster analysis.

Which of the following is NOT one of the categories of predictive analytics methods?

True or False: The G 2 statistic is a measure of the probability that can be attributed to the response that has occurred.

SCENARIO 17-2 The treemap below shows the amounts (size)measured in billions of US dollars and percentage changes from prior year (color)of business-to-consumer ecommerce sales last year for North America, Asia Pacific, Western Europe, Central & Eastern Europe, Latin America, and Middle East & Africa. -Referring to Scenario 17-2, which region has the smallest amount of business-to-consumer ecommerce sales last year?

True or False: Treemaps that use color to represent the value of a second variable, thereby increasing the data density of the displays, is an example of chartjunk.

SCENARIO 17-2 The treemap below shows the amounts (size)measured in billions of US dollars and percentage changes from prior year (color)of business-to-consumer ecommerce sales last year for North America, Asia Pacific, Western Europe, Central & Eastern Europe, Latin America, and Middle East & Africa. -Referring to Scenario 17-2, which region has the slowest growth in business-to-consumer ecommerce sales last year?

True or False: Some consider bullet graphs little more than examples of chartjunk, even as many decision makers request them due to their visual appeal, due to the amount of the space they consumes.

True or False: The LogWorth statistic is a measure of the probability that can be attributed to the response that has occurred.

SCENARIO 17-2 The treemap below shows the amounts (size)measured in billions of US dollars and percentage changes from prior year (color)of business-to-consumer ecommerce sales last year for North America, Asia Pacific, Western Europe, Central & Eastern Europe, Latin America, and Middle East & Africa. -True or False: Referring to Scenario 17-2, the Middle East & Africa region has the slowest growth in business-to-consumer ecommerce sales last year.

SCENARIO 17-4 The regression tree below was obtained for predicting the weekend box office revenue of a newly released movie (in thousands of dollars)based on data collected in different cities on the expenditure (at $25, $30, $35, $40, $45, $50, $55, $60, $65 or $70 thousand)spent on TV advertising and the number of times (10, 15, 20, 25, 30 or 35)a day the advertisement appear on TV. Business Analytics 17-15 -True or False: Referring to Scenario 17-4, the highest mean weekend box office revenue is predicted to occur with less than $45 thousand spent on TV advertisement and fewer than 25 advertisement appearances a day.

True or False: Average linkage can be used to measure the distance between clusters in cluster analysis.
