1、安装分析工具库，以2007为例，EXCEL选项－－加载项－－转到，勾选分析工具库；2、安装后在“数据”菜单自动添加了“分析”功能区；3、使用，数据－－分析－－数据分析，选择：“t－检验：平均值的成对二样本分析”。
Cohen's d- (Standardized effect size) - the value in 'Effect size' is the difference between the means divided by the standard deviation. Two-tailed paired t-test example: forty people are given treatment to reduce their cholesterol levels, with an expected reduction of 10mg/dL. The distribu...
Step 6:Use the conclusion of the t-test to give an interpretation in the context of the setting of the specific problem. Paired t test example Question: Assume that you have the following sample of paired data. Sample 1Sample 2Difference = Sample 1 - Sample 2 ...
Suppose we run the same analysis for the data in Example 1 fromTwo Sample t Test with Equal Variancesusing the t-test with independent samples and compare the results with those we obtained for paired samples: Figure 6 – Excel data analysis for independent samples ...
The paired sample comparison t test is used when the samples are not independent. For example, you might want to compare two analytical test methods. You take a series of samples; mix them well; divide them in half; and run one-half in one analytical test method and the other half in ...
Paired t-Test Example Using QI Macros If a diet claims to cause more than a 10 lb weight loss over a six month period, you could design a test using several individuals before and after weights. The samples are "paired" by each individual. You might want to know if the diet truly del...
Describes how to use the sign test to perform a paired samples test when the assumptions for a t test are not met, Examples in Excel and software are provided,
Paired T Test Example For example, imagine we have a training program and administer a pretest and posttest to the same sample of students. Consequently, each student has a pair of test scores. We need to determine whether the average change for the pairs of scores is different from zero....
value of .152344 for Example 1 by using the formula =PERM_TEST(B4:B12,C4:C12,1). We get the same result by using the formula =PERM_TEST(D4:D12,,1) or =PERM_TEST(D4:D12,0,1). The two-tailed p-value can be calculated by =PERM_TEST(B4:B12,C4:C12) or =PERM_TEST(D4:D...
