Low Academic procrastination

94.12%

90.24%

High Academic procrastination

56.46%

69.17%

  1. aRecall is TP (true positive) divided by TP (true positive) plus FN (false negative).
  2. bAccuracy is TP (true positive) divided by TP (true positive) plus FP (false positive).
  3. Recall Rate:
  4. (410 + 182) ÷ (410 + 25 + 182 + 12) =94.12%
  5. (66 + 17) ÷ (43 + 66 + 21 + 17) =56.46%
  6. Precision Rate:
  7. (410 + 182) ÷ (410 + 43 + 182 + 21) =90.24%
  8. (66 + 17) ÷ (25 + 66 + 12 + 17) =69.17%
