When we run an ANOVA, we analyze the differences among group means in a sample. In its simplest form, ANOVA provides a statistical test of whether two or more population means are equal, and therefore generalizes the t-test beyond two means. ANOVA Null and Alternatve Hypothesis Thenull hypot...

In this issue, Alsema, Wijering, Miedema, Kotah et al. and Lerma-Martin, Badia-i-Mompel et al. demonstrate the ever-growing possibilities of spatial transcriptomics by applying it to the spatially heterogeneous disease multiple sclerosis. They validate the technique by comparison to classic pathol...

One-way ANOVA was used. Data are presented as mean values ± SD. i Flow cytometry analysis of patient samples and the association between drug response and CD24 expression in MM cells (n = 15). The frequency of the subpopulation of CD138+CD24+ cells increase in 12 of 15 ...
in the 500 ms period prior to evidence onset (t-test:t(15) = 2.3,p = 0.040). This effect increased in magnitude over the course of evidence presentation, as indicated by a significant Regime × Time interaction (ANOVA; 30 50-ms time windows between 0 and 1500 ms ...
Statistical analysis of log-transformed metabolomic data was performed in ArrayStudio (Omicsoft) to compare data between experimental groups using ANOVA. For the post-hoc contrasts p-values and false discovery rate (FDR) were calculated according to method proposed by Storey and Tibshirani30. ...
