BUILT AROUND YOUR WORK
Calculators and data tools for analysts
Prepare an export for analysis. Start with a sample with headers, identifiers, and missing values. Use the relevant tools below to clean the fields and compare distributions, then keep a reconciled dataset and method note alongside the source material.
USE WITH CONTEXT
Before you use these tools
Confirm source definitions, units, missing-value handling, and sample assumptions before presenting results. Keep the original data and document any transformations.
A PRACTICAL ROUTE THROUGH THE SHELF
From raw input to reviewed output
- 1
Gather the inputs
Bring a sample with headers, identifiers, and missing values. Record where the values came from and which assumptions are still uncertain.
- 2
Prepare an export for analysis
Choose a tool to clean the fields and compare distributions. Read its method and limits, then run a small example before working through the full scenario.
- 3
Review the deliverable
Keep a reconciled dataset and method note. Compare record counts and totals with the source before interpreting a chart.

Questions before you start
Where should data analysts start?
For this workflow, begin with a sample with headers, identifiers, and missing values. Choose the tool whose inputs match the task, rather than entering incomplete values into a broader calculator. The intended outcome is a reconciled dataset and method note.
What should I verify when I clean the fields and compare distributions?
Compare record counts and totals with the source before interpreting a chart. Confirm source definitions, units, missing-value handling, and sample assumptions before presenting results. Keep the original data and document any transformations.
