Why percentages mislead, and what journalists can do about it
Percentages are everywhere in the news, but they often mislead. Jonathan Stoneman explores why '% more likely' is bad journalese, how percentages don't behave like normal numbers, and why context is always key in data reporting.
Not all data visualisations communicate clearly. In this video I am transforming a confusing chart into a clear visualization using open source tools.
The form we give our data isn’t neutral. It shapes what others see—or overlook. Learn how to match your data to its perfect outfit!
Data Journalist & Educator
Hi! I'm Ada. I am a freelance data & investigative journalist and teacher. Over more than 10 years, I made a lot of stories with small and big datasets and I am here to share what I learned along the way.
From the start of my career, I’ve loved helping other journalists get comfortable with data, brecause I believe these skills should be for everyone. Over the years, I’ve given countless lectures, taught at conferences like Dataharvest and NICAR, given guest lectures in the Master’s program in Gothenburg, and mentored journalists 1:1 through programs like IJ4EU.
I founded Data Frosch by accident, because I bought a frog hat last winter. It's a fun way to put myself out there and help others find me.
