Identify the appropriate answer for the given statement from the given choices.

Expert Solution & Answer

Answer to Problem 1MCQ

Option d. Test data is a set of data used to assess the degree and strength of a predicted relationship.

Explanation of Solution

Justification for correct and incorrect answer:

a.

Training data: This is not the correct choice as the training data refers to the existing data which have been pre-evaluated manually and these data have been assigned a class. This is used as a model which can predict whether the similar default can happen in the future or not on the basis of the existing data.

b.

Unstructured data: This option is incorrect option because unstructured data refers to the data which is not there in proper format and which is not arranged in a pre-defined manner. The unstructured data may contain the facts and details which are vital. But the unstructured data is not the set of data used to assess the degree and strength of a predicted relationship.

c.

Structured data: This option is incorrect as the structured data which are organized and remain in a fixed width with a record or a file. Such data are embedded in a relational database or spreadsheet and are quickly searchable by the search algorithms. These data are not used to assess the degree and strength of a predicted relationship.

d.

Test data: This is the correct option because it is the set of existing data which is used for evaluation of the data model. The classification algorithm tries to predict the class of the test data. It compares its prediction to the previously assigned class. This comparison can be used to evaluate the accuracy level of the model or the probability that the model will assign the correct class.
