Challenge Problems
Push your limits with advanced challenges
In a study, a model predicts 80 positive instances, with 70 true positives and 10 false positives. Meanwhile, out of 100 actual positives, 60 were predicted correctly, leading to 40 false negatives. Calculate the F1 Score.
💡 Hint: Stay focused on substituting the right values into the formulas.
Create a scenario where a model achieves high precision but low recall. Describe how the F1 Score would reflect this balance, and what implications this has.
💡 Hint: Consider how the values would play into the F1 calculations.
