Concept class $C _ { 1 }$ shows the following information for the categorical attribute Risk Factor. Use this information to answer questions 9 and 10.

$\begin{array} { l l c }\underline{ \text { Attribute Name }} &\underline{ \text { Value }} &\underline{ \text { Frequency }} \\ \text { Risk factor } & \text { High Risk } & 25 \\ & \text { Medium Risk } & 10 \\ & \text { Low Risk } & 5 \end{array}$
-What is the predictability score for the attribute value medium risk?

Question

Quizplus · Accepted Answer

The predictability score for the attribute value "Medium Risk" is calculated by dividing the frequency of the "Medium Risk" value by the sum of frequencies for all values of the attribute. Therefore,

predictability score of the medium risk = frequency of the medium risk / (frequency of low risk + frequency of medium risk + frequency of high risk)
= 10 / (5 + 10 + 25)
= 0.20

So, the best choice is C, which corresponds to a predictability score of 0.20.
