Precision-Recall Trade-off in Lead Scoring: Improve Recall
A data scientist is evaluating a custom Einstein model for a lead scoring use case. The model's precision is 0.9, recall is 0.5. What is the most important improvement priority?
Quick Answer
The answer is to increase recall to reduce false negatives. This is correct because the precision-recall trade-off in lead scoring means a model with 0.9 precision and 0.5 recall is highly selective but misses half of actual leads, creating costly false negatives—lost sales opportunities that outweigh the cost of false positives. On the Salesforce AI Associate exam, this scenario tests your understanding of how business context drives metric priorities: in lead scoring, recall is typically more critical than precision because missing a potential customer directly impacts revenue. A common trap is assuming high precision alone is ideal, but the exam emphasizes that the trade-off must align with the use case’s cost structure. Memory tip: for lead scoring, think “Recall Recovers Revenue”—if you miss leads, you miss money, so prioritize recall over precision when false negatives are the greater risk.
⚠ Common exam trap
Salesforce often tests the trade-off between precision and recall in imbalanced classification scenarios, where candidates mistakenly focus on improving precision or accuracy without recognizing that low recall (high false negatives) is the critical business problem in lead scoring.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase recall to reduce false negatives
With a precision of 0.9 and recall of 0.5, the model is highly selective but misses many actual leads (high false negatives). In lead scoring, false negatives mean lost sales opportunities, which is typically more costly than false positives. Therefore, increasing recall to capture more true positives is the most important improvement priority.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Increase recall to reduce false negatives
Why this is correct
Recall is low (0.5), meaning half of actual leads are missed. This should be improved.
- ✗
Increase precision to reduce false positives
Why it's wrong here
Precision is already high (0.9); false positives are relatively low. The main issue is false negatives.
- ✗
Optimize for an F1 score of 0.7
Why it's wrong here
The current F1 score is about 0.64; aiming for 0.7 is a goal but doesn't indicate primary priority.
- ✗
Improve overall accuracy above 80%
Why it's wrong here
Accuracy can be misleading if data is imbalanced; recall is the critical issue.

Variation 1. A data scientist is evaluating the performance of an Einstein Discovery model. They observe that the model has high accuracy but low precision for a specific prediction class. What does this indicate?
medium- A.The model is overfitted to the training data.
- ✓ B.The model correctly predicts most instances but has many false positives for that class.
- C.The model correctly predicts most instances but has many false negatives for that class.
- D.The model rarely predicts that class, leading to high accuracy.
Why B: High accuracy with low precision for a specific class indicates that while the model correctly classifies the majority of instances overall, it produces a high number of false positives for that class. Precision measures the proportion of positive identifications that were actually correct, so low precision means many of the predicted positive cases are false alarms. In Einstein Discovery, this trade-off is critical when optimizing for business outcomes where false positives are costly.
