Question: Draw a diagram and use it to define and explain the three types of ordinal, cardinal, and nominal.
Nominal Data: This is used for labeling variables, without any quantitative value. For example, colors like red, blue, and green.
Ordinal Data: This has order but no fixed measurement between values. Think of ranks like first, second, and third place.
Cardinal (Interval/Ratio) Data: This includes numerical values with a consistent interval between them. Temperature (Celsius/Fahrenheit) is interval, whereas income is ratio because it has a true zero point.
Imagine placing "red," "yellow," "green" (nominal) in a traffic light, ranking athletes (ordinal) at a race, and measuring the distance they ran in meters (cardinal).
