BACKGROUND
Statistical tables are an important component of data analysis and reports in biological sciences. However, the traditional manual processes for computation and presentation of statistically significant results using a letter-based algorithm are tedious and prone to errors.
RESULTS
Based on the R language, we present two web-based software for individual and summary data, freely available online, at http://shiny.stat.tamu.edu:3838/hassaad/Table_report1/ and http://shiny.stat.tamu.edu:3838/hassaad/SumAOV1/, respectively. The software are capable of rapidly generating publication-ready tables containing one-way analysis of variance (ANOVA) results. No download is required. Additionally, the software can perform multiple comparisons of means using the Duncan, Student-Newman-Keuls, Tukey Kramer, and Fisher's least significant difference (LSD) tests. If the LSD test is selected, multiple methods (e.g., Bonferroni and Holm) are available for adjusting p-values. Using the software, the procedures of ANOVA can be completed within seconds using a web-browser, preferably Mozilla Firefox or Google Chrome, and a few mouse clicks. Furthermore, the software can handle one-way ANOVA for summary data (i.e. sample size, mean, and SD or SEM per treatment group) with post-hoc multiple comparisons among treatment means. To our awareness, none of the currently available commercial (e.g., SPSS and SAS) or open-source software (e.g., R and Python) can perform such a rapid task without advanced knowledge of the corresponding programming language.
CONCLUSIONS
Our new and user-friendly software to perform statistical analysis and generate publication-ready MS-Word tables for one-way ANOVA are expected to facilitate research in agriculture, biomedicine, and other fields of life sciences.
背景
统计表是生物科学数据分析和报告的重要组成部分。然而,使用基于字母的算法进行具有统计学意义结果的计算和呈现的传统手动过程既繁琐又容易出错。
结果
基于R语言,我们分别在http://shiny.stat.tamu.edu:3838/hassaad/Table_report1/和http://shiny.stat.tamu.edu:3838/hassaad/SumAOV1/上提供了两个基于网络的软件,分别用于个体数据和汇总数据,可在网上免费获取。这些软件能够快速生成包含单因素方差分析(ANOVA)结果且可供发表的表格。无需下载。此外,该软件可以使用邓肯检验、学生 - 纽曼 - 库尔斯检验、图基 - 克莱默检验和费舍尔最小显著差异(LSD)检验进行均值的多重比较。如果选择LSD检验,则有多种方法(例如邦费罗尼法和霍尔姆法)可用于调整p值。使用该软件,通过网络浏览器(最好是Mozilla Firefox或谷歌浏览器)并点击几下鼠标,ANOVA的过程可以在几秒钟内完成。此外,该软件可以处理汇总数据的单因素方差分析(即每个处理组的样本量、均值以及标准差或标准误),并对处理均值进行事后多重比较。据我们所知,目前可用的商业软件(例如SPSS和SAS)或开源软件(例如R和Python),如果没有相应编程语言的高级知识,都无法执行如此快速的任务。
结论
我们用于执行统计分析并生成可供发表的单因素方差分析MS-Word表格的新型用户友好软件,有望促进农业、生物医学和生命科学其他领域的研究。
