Levels of measurement

Question 1

What are the 3 levels of measurement?

Answer 1

Nominal, ordinal, interval

Question 2

What does the level of measurement refer to?

Answer 2

The nature of the data that you are collecting/ using within your research

Question 3

What is nominal data?

Answer 3

Named categories with no true mathematical value

Question 4

How would you display nominal data?

Answer 4

Bar chart or tally chart

Question 5

What is ordinal data?

Answer 5

Ordered (ranked) data eg place in a race with no true mathematical value

Question 6

What is interval data?

Answer 6

Similar to ordinal, but the intervals between the values are equal in measurement with mathematical value EG temperature

Question 7

Nominal data AO3

Answer 7

Strength- easily generated from closed questions quickly, time efficient. Mode can be applied
Limitation- Not complex and can appear overly simplistic

Question 8

Orinal data AO3

Answer 8

Strength- more detailed than nominal data, scores are ordered in a linear fashion
Limitation- The intervals between scores are not equal and the mean cannot be applied.

Question 9

Interval data AO3

Answer 9

Strength- more informative than nominal and ordinal as the gaps between data are equal and therefore more reliable
Limitation- The intervals can be arbitrary (random, not systematic)
