Paired t-test (lite)

Compares mean difference of paired before/after values—assumes approximate normality of differences. Processing runs in your browser—Toolcore does not need your paste for the core operation on this page.

Educational statistics only—confirm assumptions before production analysis.

How to use

Paste or type in the main field, then read the output below. Use Load example when available, or open the page with ?q= / ?qb= so tickets and agents share the same input.
