Question

Which of the following is NOT an example of ordinal data

	A.	Education degree attained (High school, bachelor’s, master’s, PhD etc.)
b		Likert-responses to a survey question (Strongly Like, Like, Dislike, Strongly Dislike etc.)
	c	Seat number on a plane (15G, 14A, 17C etc.)
d		Days of week (Monday, Tuesday, Wednesday, etc.)
	e	Sizes of drinks sold at a coffee shop (Small, Medium, Large etc.)

Answer 1

An ordinal data is a level of measurement where the data can be arranged in some kind of order from lowest to highest.

a) We know that High school < Bachelor's degree < PhD

b) We know that: Strongly like > Like > dislike > Strongly Dislike

d) Monday < Tuesday < Wednesday

e) Small < Medium < Large as the size of the drinks is the order of their sizes.

The seat numbers in c) cannot be arranged in ascending or descending order.

Therefore c) cannot be an example of ordinal data.

Therefore c) is the correct answer here.
