"R t검정"의 두 판 사이의 차이

2020년 12월 5일 (토) 22:57 기준 최신판

1 개요[ | ]

R t.test()

2 1표본 t검정[ | ]

R 1표본 t검정 문서를 참고하십시오.

x = c(1:10)
t.test(x)

3 2표본 t검정[ | ]

R 2표본 t검정 문서를 참고하십시오.

A1 = c(30.02, 29.99, 30.11, 29.97, 30.01, 29.99)
A2 = c(29.89, 29.93, 29.72, 29.98, 30.02, 29.98)
t.test(A1, A2)

a = c(1,2,3,4,5,6,7,8,9,10)
b = c(5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20)
t.test(x=a, y=b)
