CD Genomics is able to use univariate analysis to study biological problems, providing customers with appropriate statistical methods for their experimental data to get the right analysis results.

Introduction of Univariate Analysis

The univariate analysis mainly includes mean and median analysis, which compares whether there is a significant difference between the means or medians of multiple variables in two subsample groups. Commonly used methods of univariate analysis when conducting analysis of differences between two sample groups include fold change analysis, t-test, and volcano plot analysis. Univariate analysis can follow the following idea: first, determine the type of information in the sample, then determine whether the data are univariate or multifactorial, then determine whether it is a single sample, two samples, or multiple samples, and finally, determine whether the data meet the prerequisites required for the test method.

The main purpose of univariate data plotting is to show the pattern of data distribution in a single feature, most commonly variance, mean, histogram, etc. Based on the univariate analysis we provide the following types of analysis results.

  • Bar Chart
  • Pie Charts
  • Histogram
  • Box line chart

Biostatistical Univariate Analysis

Statistical analysis consists of two parts: statistical description and statistical inference. Quantitative variables calculate the concentrated trend indicators and discrete trend indicators, while qualitative variables calculate the frequency and probability of individual attributes. The commonly used univariate statistical analysis methods are as follows.

One-sample t-test Paired-sample t-test Independent samples t-test
Chi-square test Independent chi-square test One-way ANOVA
Two-way ANOVA Wilcoxon rank sum test Friedman test
Mann-Whitney U test Kruskal-Wallis test

We are able to use univariate analysis to help our customers achieve high throughput data analysis in multi-omics. For questions about analysis content, project cycle, and pricing, please click online inquiry.
