Question 2

Ordinal Level of Measurment

Data at this level can be either qualitative or quantitative.
Data at this level can be arranged in order, or ranked but difference between data entries are not meaningful.

Question 3

Interval Level of Measurement

Data that can be ordered and meaningful differences between data entries can be calculated.

Question 4

Ratio Level of Measurement
