Overview

GuessThatStat turns practice questions into a focused game loop with answer evaluation, immediate feedback, score tracking, and question progression. It began as a practical study tool for classmates and became an exercise in shipping a real product for real users.

The challenge

Create an engaging statistics review experience that keeps the reasoning behind each answer visible.

The approach

I designed a short interaction loop: present a focused question, evaluate the response, explain the result, and move the learner forward while preserving a clear sense of progress.

Technical decisions

  • Keep feedback immediate so mistakes become part of the learning loop.
  • Track question progression and scoring in one consistent state model.
  • Prioritize a fast, browser-based experience that classmates could use without setup.

What I learned

  • Peer feedback reveals interaction problems that are easy to miss while building alone.
  • Reliable state transitions matter as much as visual design in an educational tool.
  • Shipping a focused product for classmates taught me to value completion and direct feedback.
