Thống kê - Bảng phân phối T

Các giá trị tới hạn của phân phối t được tính theo xác suất của hai giá trị alpha và bậc tự do. Giá trị Alpha (a) 0,05 một phía và 0,1 hai phía là hai cột được so sánh với bậc tự do trong hàng của bảng.

Một đuôi	0,05	0,025	0,01	0,005	0,0025	0,001	0,0005
Hai cái đuôi	0,1	0,05	0,02	0,01	0,005	0,002	0,001
