After reading this chapter you should understand: The logic of hypothesis testing. The steps involved in hypothesis testing. What test statistics are. Types of error in hypothesis testing. Common types of t-test s, one-way and two-way ANOVA . How to interpret SPSS outputs.doi:10.1007/978-3...
Theindependent t-testcompares the means of two unrelated/independent groups 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...

假设检验(Hypothesis Testing) 什么是假设检验 假设检验是用来判断样本与样本,样本与总体的差异是由抽样误差引起还是本质差别造成的统计推断方法。其基本原理是先对总体的特征作出某种假设,然后通过抽样研究的统计推理,对此假设应该被拒绝还是接受作出推断。 生物现象的个体差异是客观存在,以致抽样误差不可避免,所以我们不能...
Test Statistic.This group allows you to select the type of statistic used for testing hypotheses. You can choose betweenF, adjustedF, chi-square, and adjusted chi-square. Sampling Degrees of Freedom.This group gives you control over the sampling design degrees of freedom used to computepvalues...

Hypothesis Testing in DMAIC is not Mandatory Sometimes a DMAIC project can be based on Six Sigma process mapping only, i.e. SIPOC/IPO/C&E/FMEA, and the process check is a revisit to the RPN of the FMEA. In other cases you may not have a sufficiently large sample size to conclude, e...
