How do you read a logistic regression coefficient?
PICTURE THIS: HOW TO EXPLAIN IT
Simple meaning
A coefficient is the change in log-odds for a one-unit feature increase with other features held fixed.
WHY — Logistic Regression instead of guessing?
Why interviewers care about Logistic Regression:
question about Logistic Regression.
trade-offs, and what you would actually do on a AI / ML project - not buzzwords.
Name the idea, why it exists, then one short example.

STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1A coefficient is the
change in log-odds for a one-unit feature increase with other features held fixed.
- 2Exponentiating it gives an
odds ratio.
- 3How it works
Direction comes from the sign
- 4magnitudes are comparable only
after similar scaling.
- 5Common mistake
What juniors usually get wrong.

Key takeaway
A coefficient is the change in log-odds for a one-unit feature increase with other features held fixed. Exponentiating it gives an odds ratio.
