Question1: How many stages are there in the CRISP-DM process model?

Question2: You want to obtain a subset of data from a larger data set, with equally represented subgroups within the
subset.
Which node would you use to accomplish this task?

Question3: You have a data source which provides many fields needed for data scoring. Some of these fields are not
needed after the scoring is complete for the rest of the stream to operate.
Which node should be used to remove these fields?

Question4: When describing data, which two nodes address value types? (Choose two.)

Question5: What is a type of SuperNode within IBM SPSS Modeler Professional?

Question6: Which two statements are true about linear regression? (Choose two.)

Question7: You have duplicate records that must be removed from a data set in IBM SPSS Modeler Professional.
The appropriate node to perform this action would be found in which palette tab?

Question8: You have optimized four models that do not meet your performance goals. You believe that by merging
these models together you would achieve better performance.
Which node would allow you to accomplish this task?

Question9: You are managing a marketing campaign and experience poor performance for large sections of your
data.
Which approach is a correct method to improve your campaign performance?

Question10: You need to produce a variety of data files that will be viewed in external applications outside of IBM SPSS
Modeler Professional, such as IBM SPSS Statistics or Microsoft Excel.
Which palette tab would be used in this scenario?

Question11: The auditor of a credit bureau wants to verify that credit scores are between 100 and 800. Which two
nodes would accomplish this task? (Choose two.)

Question12: You are in the Business Understanding stage of the CRISP-DM process.
Which task is part of this stage?

Question13: You want to calculate the difference between the minimum and maximum values of some of your data
fields.
Which feature or mode of the Aggregate node would allow you to calculate this using a single node?

Question14: An online film streaming company is interested in building a movie recommendation model by analyzing
the historical film watching pattern of its customers. For example, analysis of the historical data may reveal
that all the customers who watched movie A and movie B, also had a high likelihood of watching movie C.
This information can then be used to recommend movie C to all future customers who watch movies A and
B.
Which modeling node would be used to build such a movie recommendation model?

Question15: You have collected data about a set of patients, all of whom suffered from the same illness. During their
course of treatment, each patient responded to one of five medications. The column. Drug, is a character
field that describes the medication. You need to find out which proportion of the patients responded to
each drug.
Which node should be used?

Question16: A client has a business goal of increasing units sold by 10 percent.
Which two data mining objectives would be consistent with their business goal? (Choose two.)

Question17: You are provided with a data set that includes daily maximum temperatures at an airport. Your analysis
requires you to create a new field containing the maximum temperature from five days ago.
Which node would be used for this purpose?

Question18: Besides providing a new predicted value, which additional task would some modeling nuggets perform?

Question19: You have designed a model predicting the goals scored for each player in the World Cup and now want to
evaluate the model using held-out scoring data.
Which node is designed to produce this actual vs. predicted model evaluation?

Question20:
Referring to the exhibit, from which node is the output generated and on which data does it show greater
accuracy?

Question21: You are working on a project where the business objective is to increase sales revenue.
With which CRISP-DM process model stage would you start?

Question22: When using IBM SPSS Modeler Professional, you want to organize your streams, annotations, stream
output, and results within the interface.
Which two tabs within Modeler will allow you to accomplish this goal? (Choose two.)

Question23: A telecommunication company wants to predict their customers' purchase decisions from four service
options (categorical value).
Using IBM SPSS Modeler Professional, which modeling node should be used?

Question24: You have a data set with numeric fields (columns) that contain null values. You want to replace each of
these null values with the value of zero.
Which node will you use to accomplish this task?

Question25: You have a data set with two different date fields (columns). Your analysis requires you to create a new
field which is the number of calendar days elapsed between these two dates.
Which node will you use to accomplish this task?

Question26: You need to export data using IBM SPSS Modeler Professional.
Which two nodes should be used to accomplish this task? (Choose two.)

Question27: You want to create a Filter node to keep only a subset of the variables used in model building, based on
predictor importance.
Which menu in the model nugget browser provides this functionality?

Question28: Which capability would be achieved by only creating a SuperNode in IBM SPSS Modeler Professional?

Question29: You need to output only a list of field names, arranged in a single column, for a reporting function. You
have already imported the data using a Database node and know it has 25,000 records.
Which node sequence would yield the desired output?

Question30: You have executed a model node which has generated a model nugget connected to your stream's data
source.
What will allow the stream to score data with this new nugget?

Question31: You want to illustrate the strength of the relationship between blood pressure and prescription drug to
which a patient responded. The blood pressure variable has been binned into ten values.
Which node should be used?

Question32: Your analysis requires you to export data in a tab delimited file.
Which export node will you use to accomplish this task in IBM SPSS Modeler Professional?

Question33: What are two purposes of model nuggets? (Choose two.)

Question34: Which statement is correct about automated modeling nodes in IBM SPSS Modeler Professional?

Question35: You have a model nugget in the Models palette, but the stream used to create the model is not available.
You want to refresh the model by rebuilding it on a new data set, but using the same variables and settings
used to build the original model nugget.
Which capability in the modeling nuggets in the Models palette will you use for this purpose?
