Reading Numbers in Words

Introduction to data and graphing vocabulary.

When writing for academics or exams, using basic words like "number" or "change" isn't precise enough. To sound professional, you need the exact vocabulary to describe what you see.

Let's start with the foundation:

Data: The raw, unorganized facts or numbers collected for reference. (e.g., A spreadsheet of daily temperatures).
Statistic: A single number calculated from that data to summarize it. (e.g., The average temperature was $25^\circ$ C).

Pro tip: Think of data as the raw ingredients, and a statistic as the baked cake.
