From hypothesis to conclusion: the essential role of statistics in science
Bibliographic record
Abstract
This study introduces an experiential learning approach in statistical education, leveraging a real-world experimental design to elucidate the scientific method’s role in statistics. Targeting high school and college students, the methodology involves engaging participants in a hands-on experiment, where the primary objective is to ascertain whether two distinct products are differentiable based on a specific characteristic, such as taste. The experiment encompasses several key stages: designing the study, formulating, and testing hypotheses, participating as experimental units, analyzing the gathered data, and interpreting the results to draw statistical inferences. This approach not only facilitates a practical understanding of statistical concepts, but also highlights the importance of experimental design, hypothesis testing, data analysis, and probability interpretation in real-world scenarios. Through this immersive experience, students are expected to gain a deeper appreciation of statistics as a scientific discipline and its applicability in everyday life.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
