What Physiology Taught Me About Reading a Dataset
Before I learned to code, I learned to ask what's actually going on in a system. Here's how that instinct changed the way I approach data.
A body in homeostasis is a dataset that has learned to balance itself. Studying physiology meant staring at feedback loops until a spike or a dip stopped being noise and started being a signal with a cause. That habit is the most useful thing I brought into data work.
The pattern comes before the tool
It's tempting to reach for a model the moment you open a CSV. But a model can only amplify what you already understand about the data. So I sit with the distribution first — where it clusters, where it's empty, what a gap is quietly telling me.
A missing value is not an absence of information. It's information about the process that produced it.
In the Wisconsin Breast Cancer analysis, the measurements that separated benign from malignant weren't the flashy ones — they were the ones a clinician would have looked at first. Domain sense and data sense are the same sense, pointed in two directions.
