About this Gig

You've collected the responses. Now you need to know what they actually say.


I take raw survey exports and turn them into findings you can present 

not a spreadsheet of percentages, but a clear read on what the data 

supports and what it doesn't.


WHAT YOU GET


- Data cleaning first straightlining, speeders, duplicates and 

 incomplete responses flagged before anything is calculated

- Descriptive stats and cross-tabs, broken out by the segments that 

 matter to you

- Significance testing, so you know which differences are real and 

 which are sampling noise

- Open-text responses coded into themes with representative quotes

- Clean charts, ready to drop into a report or deck

- A written summary in plain language


WORKS WITH


SurveyMonkey, Google Forms, Qualtrics, Typeform, Excel or CSV exports. 

If you have raw data, I can work with it.


HOW I WORK


I report what the data shows, including when it doesn't support what you 

were hoping to find. A finding that survives scrutiny is worth more than 

a chart that flatters the hypothesis especially if you're presenting 

to people who will push back.
