---

Question1: You have a large amount of data from which you want to build a model. Although many of the records of data are complete, there are substantial amounts of records which contain missing data. The records containing incomplete information should be excluded from analysis.
Which node will exclude the undesired records?

Question2: 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?

Question3: You need to score future data using an association model.
Which statement describes the data format requirement to do this?

Question4:
Referring to the exhibit, from which node is the output generated and on which data does it show greater accuracy?

Question5: Which two types of missing values are automatically recognized by IBM SPSS Modeler Professional without being explicitly defined by users? (Choose two.)

Question6: 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?

Question7: You want to obtain a subset of data from a larger data set, with equally represented subgroups within thesubset.
Which node would you use to accomplish this task?

Question8: 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?

Question9: Which statement is true about association models?

Question10: 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?

Question11: Which palette contains the Data Audit node?

Question12: You have optimized four models that do not meet your performance goals. You believe that by mergingthese models together you would achieve better performance.
Which node would allow you to accomplish this task?

Question13: 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?

Question14: Which task is part of the Data Understanding stage of the CRISP-DM process model?

Question15: What is a type of SuperNode within IBM SPSS Modeler Professional?

Question16: 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?

Question17: 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.)

Question18: Which statement is correct about the Reclassify node?

Question19: 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?

Question20: 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.)

Question21: You need to export data using IBM SPSS Modeler Professional.
Which two nodes should be used to accomplish this task? (Choose two.)

Question22: You are attempting to flag outliers in a data set across multiple fields.
In IBM SPSS Modeler Professional, what would be the appropriate node to use?

Question23: 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?

Question24: 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?

Question25: Which two statements are true about linear regression? (Choose two.)

Question26: What is a unique capability of scripting in IBM SPSS Modeler Professional?

Question27: 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?

Question28: 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?

Question29: 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?

Question30: What is the primary purpose of the Partition node in a modeling effort?

Question31: 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?

Question32: What is an accurate description of the purpose of data segmentation?

Question33: How many stages are there in the CRISP-DM process model?

Question34: You have two data sets. One data set contains customer name and age information along with a customer ID. The second data set contains the customer ID along with address information. There are no addresses which do not belong to a customer, there are customers which have no address, and there are customers which have multiple addresses.
Which type of join will display all customers who have no recorded address?

Question35: Which capability would be achieved by only creating a SuperNode in IBM SPSS Modeler Professional?

Question36: You are working on a project where the business objective is to increase customer retention. You havecompleted the Data Preparation stage of the CRISP-DM process model.
What is the next stage?
