Repeated measures are obtained whenever a specific response is measured repeatedly in a set of units. Examples are hearing thresholds measured on both ears of a set of subjects, birth weights of all litter members in a toxicological animal experiment, or weekly blood pressure measurements in a ...

A repeated measures ANOVA will not inform you where the differences between groups lie as it is an omnibus statistical test. The same would be true if you were investigating different conditions or treatments rather than time points, as used in this example. If your repeated measures ANOVA is ...
Repeated measures models are regression models in which observations have multiple response variables. Multiple analysis of variance (MANOVA) is a statistical technique used to determine whether vectors of response data are statistically different. Repeated measures models and MANOVA are commonly used in ...

由于4个时间点的数据属于重复测量数据,可以使用单因素重复测量方差分析(One-Way Repeated Measures ANOVA)。但需要满足5个条件: 条件1:观察变量唯一,且为连续变量。本研究中观察变量为生化指标浓度,且为连续变量,该条件满足。 条件2:观察变量为重复测量数据,即不满足独立性。本研究中4个时间点测量的生化指标浓度均...
使用单向重复测量 ANOVA (a one-way repeated-measures ANOVA)在三个条件下比较时间、任务负载和可用性分数。 https://www.bilibili.com/video/BV1Ms41177gs?p=37 (1)首先,使用 Shapiro-Wilk 检验 [43] 验证了分布正态性假设http://www.datasoldier.net/archives/2290。

As we mentioned under assumptions, repeated measures ANOVA requires sphericity and Mauchly’s test evaluates if this holds. The p-value (denoted by “Sig.”) is 0.264. We usually state that sphericity is met if p > 0.05, so the sphericity assumption is met by our data. We don't need ...
1. What is Repeated Measures ANOVA? SPSS repeated measures ANOVA tests if the means of 3 or more metric variables are all equal in some population. If this is true and we inspect a sample from our population, the sample means may differ a little bit. Large sample differences, however, ar...
