The hypotheses for the 2-sample t test are as follows: The mathematical details of the 2-sample t test are not covered here. However a key point is that the ability to detect differences in averages depends on both the difference between the sample averages and the variation within each ...

The test statistic is a t statistic because the population variance is not known. df=16-1=15 For a two-tailed test at the .05 level of significance and with 8 degrees of freedom, the critical region consists of t values greater than +2.131 or less than -2.131 Step 3: Calculate the ...

检验统计量(test statistic):用于假设检验计算的统计量。 例如:Z值、t值、F值、卡方值。 显著性水平(level of significance):当零假设为真时,错误拒绝零假设的临界概率,即犯第一类错误的最大概率,用α表示。 例如:在5%的显著性水平下,样本数据拒绝原假设。
measured on the Interval or ratio scale. TheSPSSt-test procedure allows the testing of the hypothesis when variances are assumed to be equal or when are not equal and also provides the t-value for both assumptions. This test also provides the relevant descriptive statistics for both of the ...
