t检验有以下几种:单样本t检验成对样本t检验独立样本t检验,其中包含(双样本等方差假设,双样本异方差假设)以及大量样本(样本量大于30)的z-检验。如图:1.单样本t检验单样本均数比较的t检验(onesamplet-test)即已知样本均数X(代表未知总体均数与已知总体均数M0(一般为理论值、标准值或经过大量观察所得稳定值等)的...
In a one-sample t-test, we take a small sample of data from a large population. For example, a small sample of 10 students from a large population of 150 students. The formula then takes the average of a small sample and compares it with the average of the population to check if the...
T-tests are hypothesis tests that assess the means of one or two groups. Hypothesis tests use sample data to infer properties of entire populations. To be able to use a t-test, you need to obtain a random sample from your target populations. Depending on the t-test and how you configure...
The Wilcoxon Signed-Rank test is a nonparametric equivalent of the One sample t-test. Run it in Excel using the XLSTAT statistical software.
In an empty cell, start the t-test function by typing "=T.TEST(". Then insert the 2 arrays. Input Your Data Arrays in T-Test Function Step 2: Add the Tail Distribution Value Add the tails parameter after the comma. If you're conducting a one-tailed distribution test, input "1"; ...

The Formula of T.TEST includes 4 types of arguments: Array1:This is the first set of the sample you are testing. Array2:This is the second set of the sample you are comparing. Tails:This is the number of tails for the distribution. There are two types of tails are there. 1. One-...
