OC curve and confusion matrix can examine the accuracy of the classification. Outliers: Outliers affect the division of the nodes. Three approaches to handle outliers are: Omit if it is a mistake. Compare the results between with and without outliers. Use of median or trimming mean.
Confusion matrix - Wikipedia
The confusion matrix. When referring to the performance of a classification model, we are interested in the model’s ability to correctly predict or separate the classes. When looking at the errors made by a classification model, the confusion matrix gives the full picture. Consider e.g. a three class problem with the classes A, B, and C.

The confusion matrix illustrates that 560 of non-hot Weblogs out of 621 are classified correctly and 61 of non-hot Weblogs are misclassified. In addition, it shows that 309 of hot Weblog are classified correctly and 46 of hot Weblog are misclassified. Here is the decision tree that is obtained by running the J48 classifier.

The verbal or nonverbal feedback from the audience may suggest a lack of interest or confusion. Topic selection does not relate to audience needs and interests. The presenter is able to keep the audience engaged most of the time. When feedback indicates a need for idea clarification, the speaker makes an attempt to clarify or restate ideas.
