在网上搜索了很多资料,发现有一篇文章实用、详细而全面介绍了如何在SPSS使用two-way ANOVA(我的SPSS 版本是16,如下文运新two-way ANOVA 没有问题,但是在Syntax(用于比较同一treatment下不同时间之间差异或则同一时间点各treatment之间的差异)时界面不同)。转载如下:http://statistics.laerd.com/spss-tutorial
To determine whether your dependent variable is normally distributed for each combination of the levels of the two independent variables see our Testing for Normality guide that runs through how to test for normality using SPSS using a specific two-way ANOVA example. In SPSS, homo...
Two-way MANOVA Two-way MANOVAcan be considered to be an extension of one-way MANOVA to support two factors and their interaction or as an extension to two-way ANOVA to support multiple dependent variables. Univariate case Two-way ANOVA investigates the effects of two categorical variables on a...
platform for 0.3 nM target and other interfering nucleic acids using 50 mM [Fe(CN)6]3–/4–, using two-way ANOVA: *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001,pvalue of 0.00001, 0.000048, 0.000173 referring to, without NgAgo for EBV, gDNA 3 f...
Statistical analyses were performed using two-way ANOVA. *P < 0.01 denotes significant change from the untreated, obtained from ANOVA. Number of * presents the degree of significance. Full size image Conclusion The study revealed the benefit of using microwave-alkali pretreatment for enhanced ...
Both the mixed ANOVA and two-way repeated measures ANOVA involve two factors, as well as a desire to understand whether there is an interaction between these two factors on the dependent variable. However, the fundamental difference is that a two-way repeated measures ANOVA has two "within-...
We used two-way ANOVA to test the effects of warming (W), N addition (N), and their interactions (W × N) on response variables. We also conducted multiple comparisons using the least significant difference test to determine the differences among treatments for each variable. Response ...
The result obtained was analyzed using a two-way ANOVA factorial experimental design to test the significance of the various sources of variation. From the result obtained, source of variation for sample and interactions were non-significantly different from each other which means that irrespective of...
For a two-way ANOVA, possible alternative hypothesis are (1) there is a difference in means of factor A, (2) there is a difference in means of factor B, and (3) there is an interaction between the factors A and B. For this analysis, the alternative hypothesis is declared as(7.6)HA...
Differences among groups were assessed by one-way ANOVA with Bonferroni post hoc correction to identify statistical differences among three or more treatments. Alpha levels were set at 0.05 and a p-value of ≤0.05 was set as the criteria for statistical significance. All data are presented as ...
