Prepare the data
Import a simulated fixed-horizon experiment with one row per randomised unit.
01 / THE IDEA
A/B Test Analysis in practice.
An experiment analyser should validate assignment and exposure data before estimating treatment effects. Statistical significance does not by itself establish practical value.
Real-world use case · Proposed extension
A possible application for product analytics classes: Help product learners review small experiments without cherry-picking favourable metrics. This extension is not delivered by the supplied starter.
02 / THE BUILD
How to build a a/b testing analyzer project
step by step.
Build the experiment
Calculate absolute and relative effects, confidence intervals and a prespecified hypothesis test.
Evaluate the result
Check sample-ratio mismatch, missing outcomes and false-positive rates on A/A simulations.
Define a reviewable output
Produce a decision report with effect size, uncertainty and the original stopping rule.
03 / SOURCE SNAPSHOT
What the a/b testing analyzer starter actually does.
The supplied starter creates 800 synthetic binary-classification rows with ten numeric features. It makes a stratified train/test split, fits a scaled RandomForestClassifier pipeline and prints a classification report.
SOURCE EXCERPTPython
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(
n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(classification_report(y_test, predictions))Important limitation
The supplied classification report does not estimate treatment effects or analyse experiments. Synthetic binary classification does not establish performance on the proposed application. The source report uses one split; it supplies no deployment or real-world validation.
04 / BEYOND THE CLASSROOM
Where a a/b testing analyzer project could go next.
PROPOSED BUSINESS CONCEPT
A/B Test Analysis: a pilot concept
Proposed extension: Help product learners review small experiments without cherry-picking favourable metrics.
WHO IT COULD SERVEProduct analytics classes
FIRST MVPProduce a decision report with effect size, uncertainty and the original stopping rule.
KEY RISKMultiple testing and optional stopping
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
05 / WHAT YOU TAKE AWAY
What a a/b testing analyzer project puts on your resume.
- Calculate absolute and relative effects, confidence intervals and a prespecified hypothesis test.
- Check sample-ratio mismatch, missing outcomes and false-positive rates on A/A simulations.
- Produce a decision report with effect size, uncertainty and the original stopping rule.
- Explain this limitation: The supplied classification report does not estimate treatment effects or analyse experiments.

06 / QUESTIONS STUDENTS ASK
A/B Testing Analyzer project FAQs.
- Is this suitable as a final year project?
- Yes — it’s appropriate for final year students with intermediate machine-learning and statistics knowledge; focus on experiment validation and treatment-effect estimation rather than only classification metrics.
- What should I learn or prepare before starting?
- You should be comfortable with Python, pandas and SciPy, plus experimental design, causal inference basics (ATE, treatment assignment), hypothesis testing and data cleaning practices.
- How can I evaluate progress and how long will it take?
- Evaluate by adding exposure validation, balance checks, and treatment-effect estimators (ATE/ATE with covariate adjustment); estimated timeframe is 6–12 weeks depending on scope and experiments simulated.
