Exam 17: Business Analytics

Single linkage can be used to measure the distance between objects in cluster analysis.

The Akaike information criteria (AIC)or the corrected Akaike information criteria (AICc)can be used to compare alternative models chosen by the classification tree.

SCENARIO 17-1 The table below contains the sparklines for the rates of return (in percentage)for three different stocks from 2007 to 2013. -Referring to Scenario 17-1, the rates of return of stock ____ have the smallest variation among the three.

SCENARIO 17-7 The output below shows the results of cluster analysis on the different regions of the world (North America, Asia Pacific, Western Europe, Central & Eastern Europe, Latin America, and Middle East & Africa)based on the amounts (in billions of US dollars)and the percentage changes from prior year of business-to-consumer e-commerce sales last year. -Referring to Scenario 17-7, the "complete" method is used to measure the maximum distance between clusters.

Dashboards may contain all but which of the following?

SCENARIO 17-1 The table below contains the sparklines for the rates of return (in percentage)for three different stocks from 2007 to 2013. -Referring to Scenario 17-1, the pattern of the rates of return of stock ____ and stock ____ are similar.

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. -Referring to Scenario 17-4, how many cities were used in generating the regression tree?

SCENARIO 17-1 The table below contains the sparklines for the rates of return (in percentage)for three different stocks from 2007 to 2013. -Referring to Scenario 17-1, the sparklines enable you to predict that the rates of return of the stock market in 2014 will be higher than in 2013.

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. -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 $50.

Each observation is treated as its own cluster at the beginning in hierarchical clustering.

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. -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.

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. -Referring to Scenario 17-4, the highest mean weekend box office revenue is predicted to occur with $55 thousand spent on TV advertisement and at least 25 advertisement appearances a day.

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. -Referring to Scenario 17-3, what is the lowest rate of switching into the bundled offering?

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 e-commerce sales last year for North America, Asia Pacific, Western Europe, Central & Eastern Europe, Latin America, and Middle East & Africa. -Referring to Scenario 17-2, the Middle East & Africa region has the slowest growth in business-to-consumer ecommerce sales last year.

Which of the following is NOT among the three broad categories of analytic methods?

Dashboards may contain all but which of the following?

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. -Referring to Scenario 17-4, the first split occurs at 25 TV appearances a day of the advertisement.

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. -Referring to Scenario 17-4, the highest mean weekend box office revenue is predicted to occur with $30 thousand spent on TV advertisement and 30 advertisement appearances a day.

Ward's minimum variance can be used to measure the distance between clusters in cluster analysis.

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 e-commerce 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?
