Question: What is data

Áine Uí Ghiollagáin answered on 28 May 2023:

Data for me are numbers that tell us something useful about the world. For example, if a patient gets better, how do doctors know that the medicine they used has worked? maybe the person got better on their own. Collecting information about patients and how many of them got better with – or without – a medicine helps us understand what works and what doesn’t.
