Transparent methods
Reports will identify data sources, included states and dates, excluded records, calculation methods, and the data-through date.
Research foundation
ScratchBest Data Research
Future reports will analyze ScratchBest’s accumulated historical lottery data. Every report will state its source scope, collection period, sample definition, metric definitions, and limitations.
Research reports are coming from the historical dataset
No report is published yet. ScratchBest is auditing historical coverage before choosing a study, so this page does not present unverified findings or conclusions.
Limits first
Historical data can contain collection gaps and source changes. Reports will describe those limits and avoid claims the available sample cannot support.
What future reports may include
A reviewed report may include a summary, author, publication and update dates, data-through date, states included, methodology, sample size, findings, charts or tables, downloadable data when appropriate, and limitations.
