Suppose we want to save some data about a research participant who comes into the lab. Specifically, we need to record the participant's Research ID, gender, age (years), weight (kg), and height (cm). We know the following: ID: P01 Gender: Male Age: 25 years Weight: 88.6 kg Height: 188 cm We can define variables for each category, call them ID, gender, age, weight, height, and assign each its correct value
