Independent-samples T Test: The independent-samples t-test (or independent t-test, for short) compares the means between two unrelated groups on the same continuous, dependent variable.(1 variable -> 2 different groups)
e.g. gender(남/여)에 따른 몸무게 평균의 차이
e.g. 시험(중간/기말)에 따른 영어 평균의 차이
paired-sample T Test: The dependent t-test (called the paired-samples t-test in SPSS) compares the means between two related groups on the same continuous, dependent variable.
(1 variable -> 2 related groups)
e.g. 1반의 중간/기말고사 성적 평균차
One-way ANOVA: The one-way analysis of variance (ANOVA) is used to determine whether there are any significant differences between the means of two or more independent (unrelated) groups (although you tend to only see it used when there are a minimum of three, rather than two groups).
(1 variable -> more than 3 groups)
