What is the High School Math B Statistical Inference Quiz?

This is a game-like free web quiz for practicing statistical inference topics studied in high school Math B, especially from Grade 11 to Grade 12.

All questions, choices, hints, diagrams, data settings, and numerical values are original. The app does not reproduce textbook, workbook, mock exam, entrance exam, or official test materials.

Practice probability, estimation, and testing

The quiz covers probability distributions, expected value and variance, binomial distribution, normal distribution and standardization, sampling distributions, confidence intervals, hypothesis testing, and data interpretation.

Questions are designed for quick review from Grade 11 to Grade 12 level while keeping the existing time attack, ranking, and My Page features.

Dynamic hints and original diagrams

Hints change depending on the current question. They can show self-made SVG diagrams such as distribution bars, normal curves, confidence interval bands, and hypothesis testing flow charts.

My Page stores challenge history, best records, and often missed questions, making repeated review easier.

What students can review here

Students can practice the flow from probability distributions to statistical inference: reading a distribution table, calculating expected value and variance, using binomial and normal distributions, standardizing values, and interpreting the result.

The estimation courses focus on sample means, sample proportions, standard errors, margins of error, and confidence intervals. The testing course focuses on null and alternative hypotheses, p-values, significance levels, and decision wording.

Useful for short review before lessons and tests

Each question is short and uses self-made numerical settings, so it can be used for warm-up practice, homework review, or quick checks before regular tests.

Teachers and families can also use the course list to see which part the learner is practicing: expected value, binomial distribution, normal distribution, sampling distribution, confidence interval, hypothesis testing, or data reading.

Focus on understanding, not only calculation

Statistical inference is easy to confuse if students only memorize formulas. This quiz also asks about interpretation, sampling bias, correlation and causation, and how to read a small data summary.

The dynamic hints show the formula, the current calculation, and a simple original diagram so that students can review why the answer is reasonable.
