From single-variable ANOVA to multi-variable power—redefining how you analyze Completely Randomized Designs.
For researchers, students, and agricultural scientists, statistical analysis is often the bottleneck between gathering data and publishing results. We built DataFlex-CRD to solve that problem with a clean, web-based interface for Completely Randomized Design (CRD) analysis.
Today, we are thrilled to announce the release of DataFlex-CRD 2.0.
We’ve taken the robust statistical core you rely on and wrapped it in a completely re-engineered architecture. Version 2.0 isn't just an update; it’s a transformation into a comprehensive research suite that handles complex data, advanced transformations, and professional visualization—all within your browser.
Here is what’s new in DataFlex-CRD 2.0.
1. Multi-Variable Analysis (Long Format Support)
The days of analyzing one column at a time are over.
Batch Processing: Upload a single "Long Format" CSV file containing multiple variables (e.g., Growth, Yield, Chlorophyll Content).
Intelligent Parsing: The app automatically generates individual analysis tabs for each variable.
Auto-Replication Detection: Missing a replication column? No problem. The smart engine auto-detects replications based on your treatment names.
2. A Powerful Transformation Engine
Real-world data rarely fits a perfect bell curve. Version 2.0 gives you granular control over normalizing your data.
Standard Library: One-click access to Log10, Square Root, and Arcsine transformations.
Degrees vs. Radians: Specifically for Arcsine, you can now choose between Radian output or Degree output, aligning with your preferred reporting standard.
Advanced Corrections: We’ve implemented the robust Bartlett Correction ($1/4N$) for proportional data containing 0s and 1s.
Variable-Specific Settings: Apply a Log transform to "Variable A" and a Square Root to "Variable B" in the same run.
Custom Formulas: Need something unique? Write your own transformation formula (e.g.,
1/x) and even define the back-transformation logic for your final report.
3. Expanded Statistical Rigor
We’ve gone beyond Fisher’s LSD to offer more conservative testing options.
Tukey’s HSD: You can now toggle between Fisher’s LSD (Critical Difference) and Tukey’s HSD (Honestly Significant Difference).
Significance Matrices: For every variable, generate a clear Pairwise Comparison Matrix showing exactly which treatments differ ("X") and which do not ("-").
Overlapping Grouping: Our refined algorithm correctly assigns overlapping group letters (e.g., $a, ab, b$) for both LSD and Tukey tests.
4. The Master Result Table
The crown jewel of Version 2.0 is the Master Result Table.
After processing all your variables, the app compiles a single, publication-ready summary table. It aligns all treatments and displays:
Original Mean ± Standard Deviation.
Superscripted grouping letters ($^{a, b, c}$).
(Optional) Transformed mean values in parentheses.
Summary rows for SEm, SE(d), CD, and CV%.
New in v2.0: You can customize the layout of this table cells (e.g., placing the transformed value on a new line) via the settings menu.
5. Professional Visualization with Plotly
Numbers are great, but charts tell the story.
Interactive Graphs: Generate Bar, Line, or Scatter plots directly from your Master Table data.
Error Bars: Standard Deviation error bars are automatically calculated and plotted.
Full Customization: Open the new Settings Modal to change background colors, error bar colors, and define your own 15-color data palette.
Export: Download your charts as high-resolution PNGs or SVGs.
