Which of the following plots is used to visualize the performance of a binary classifier?1 pointo A) Scatter ploto B) ROC curveo C) Bar charto D) Histogram

The plot used to visualize the performance of a binary classifier is B) ROC curve.

Here's why:

A) Scatter plot: This is used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another. It is not specifically used for binary classifiers.

B) ROC curve: This is a plot of the true positive rate against the false positive rate for the different possible cutpoints of a diagnostic test. It shows the tradeoff between sensitivity and specificity and is used to measure the performance of a binary classifier.

C) Bar chart: This is used to compare the quantity, frequency, etc. of different categories of data. It is not specifically used for binary classifiers.

D) Histogram: This is used to show the underlying frequency distribution of a set of continuous or discrete data. It is not specifically used for binary classifiers.
