What is an Independent Samples T Test? Use an independent samples t test when you want to compare the means of precisely two groups—no more and no less! Typically, you perform this test to determine whether two population means are different.
獨立樣本t檢定用於比較兩樣本的平均數是否有顯著差異，以下為其公式、使用方法及SPSS操作。 一、使用狀況. Two sample t-test：比較 兩組 樣本的平均值是否有差異。 例如：分析使用A牌飼料與B牌飼料餵養的乳牛，其每季平均生產的鮮乳量是否有差異。 二、前提假設. 1. 依變數 (Dependent variable)： 必須是 連續變數 (continuous variable) 必須為 隨機樣本 (Random variable) →從母群體 (Population)中隨機抽樣得到. 2. 依變數的母群體：必須是 常態分佈 (Normal Distribution) 3.
2024年7月10日 · The Independent Samples t Test compares the means of two independent groups in order to determine whether there is statistical evidence that the associated population means are significantly different. The Independent Samples t Test is a parametric test. This test is also known as: Independent t Test. Independent Measures t Test.
The independent samples t test (also called the unpaired samples t test) is the most common form of the T test. It helps you to compare the means of two sets of data. For example, you could run a t test to see if the average test scores of males and females are different; the test answers the question, “Could these differences have occurred ...
The independent-samples t-test (or independent t-test, for short) compares the means between two unrelated groups on the same continuous, dependent variable.
The independent t-test, also called the two sample t-test, independent-samples t-test or student's t-test, is an inferential statistical test that determines whether there is a statistically significant difference between the means in two unrelated groups.
「獨立樣本 T 檢定」程序，乃是用來比較兩組觀察值的平均數。 理論上，這個檢定的受試者應該隨機地指定給兩個小組，這樣一來，回應差異都是來自處理方式（或者未予處理），而不是其他因素造成的。
