Getting Started with OpEx360 Stat Tools
OpEx360 includes a full Lean Six Sigma statistical toolkit — 90 tools covering every DMAIC phase, from basic descriptive statistics to advanced DOE and SPC. This guide walks you through everything you need to know to run your first analysis in under 5 minutes.
No installation
Runs entirely in your browser — no software to install, no licence required.
Data stays local
Your data never leaves your browser. Nothing is sent to any server.
LSS-native
Every tool is designed for DMAIC workflows, not generic statistics.
How the Tools Work
Client-side computation
All statistical calculations happen in your browser using JavaScript. There is no server processing your data — results are instant and completely private.
Paste-from-Excel data grid
Every tool has a built-in data grid. Copy a column from Excel and paste it directly — the grid parses comma, tab, or newline-separated values automatically.
Plain-language interpretation
Every result includes an interpretation panel that explains what the output means in plain English — including whether your assumptions are met and what to do next.
MBB Coach AI assistant
Click the MBB Coach button (bottom-right) on any tool page to ask questions. The AI provides guidance on methodology, interpretation, and next steps — without seeing your data.
Assumption checker
Tools that require normality or equal variance automatically check these assumptions and show a traffic-light status — green means proceed, amber means check, red means use a non-parametric alternative.
Export to PDF and CSV
Export any analysis as a branded OpEx360 PDF report or raw CSV. The PDF includes your charts, results table, and interpretation — ready for gate reviews and project reports.
Entering Your Data
Copy from Excel or any spreadsheet
Select a column (or multiple columns) in Excel and press Ctrl+C (Cmd+C on Mac). Then click inside the data grid in the tool and press Ctrl+V. The grid will automatically detect column separators and populate the rows.
Include the column header row — the grid will use it as the variable name.
Type or paste raw numbers
You can also type numbers directly, one per row, or paste a comma-separated list. The grid accepts: newline-separated, comma-separated, tab-separated, and space-separated values.
Minimum sample sizes: most tests need ≥ 5 per group; capability studies need ≥ 30; Gauge R&R needs ≥ 10 parts × 2–3 operators × 2–3 replicates.
Label your columns
Click the column header to rename it (e.g. 'Before', 'After', 'Machine A'). Column names appear in charts, results tables, and exported reports.
Use descriptive names — they make your exported reports self-explanatory.
Use the Transform panel for non-normal data
If your data is skewed or non-normal, click the Transform button in the data grid. It applies Box-Cox, log, square root, or other transformations and shows a before/after normality comparison.
Box-Cox transformation automatically finds the optimal lambda — you don't need to guess.

Your First Analysis — Step by Step
Follow these 6 steps to complete your first analysis. Click each step to mark it as done.
Collect your data
Gather at least 20–30 data points from your process. More data = more reliable results. You can use process logs, measurement records, or export from your ERP/MES system.
Paste your data
Click the data grid and paste directly from Excel or CSV. Each column becomes a variable. Label your columns (e.g. 'Cycle Time', 'Defect Count'). The grid accepts comma-separated, tab-separated, or space-separated values.
Run the analysis
Click Analyse. The tool instantly computes mean, median, standard deviation, skewness, kurtosis, and runs a Shapiro-Wilk normality test. The histogram shows your distribution shape with a normal curve overlay.
Read the interpretation panel
Every tool includes a plain-language interpretation at the bottom. It tells you what the results mean, whether your assumptions are met, and what to do next — no statistics degree required.
Export your results
Click Export CSV to download the raw results, or Export PDF to generate a branded OpEx360 report with your analysis, charts, and interpretation — ready to include in your project charter or gate review.
Green Belt vs Black Belt Tools
Every tool is tagged with a belt level. Here is what that means in practice.
GB tools are designed for practitioners running focused improvement projects. They require no advanced statistical background — the tools guide you through assumptions, interpret results in plain English, and suggest next steps.
Example tools:
Start with the Hypothesis Wizard — it selects the right GB test for your question automatically.
BB tools are for practitioners leading complex, multi-factor projects. They assume familiarity with statistical concepts and are used for advanced MSA, regression modelling, DOE, and multivariate analysis.
Example tools:
Start with the DOE Wizard to choose the right experimental design for your project.

Need help choosing the right test?
Use the Hypothesis Wizard — it asks three questions (data type, number of groups, paired or independent) and recommends the correct statistical test with a direct link to run it. Open Hypothesis Wizard →
