Question

if a confusion matrix shows 46 tp, 6 fn, 500 tn, and 4 fp, what is the precision ratio? (round your answer to 2 decimal places.)

Answer 1

Explanation:

Precision is defined as the ratio of true positives (TP) to the total predicted positives (TP + FP). In this case, the confusion matrix shows 46 TP and 4 FP, so the precision can be calculated as:

precision = TP / (TP + FP) = 46 / (46 + 4) = 0.92

Rounding to 2 decimal places, the precision ratio is 0.92.
