17
Q
Ordinal Level of Measurement
A
- Qualitative or Quantitative
- Differences between Data entries is NOT meaningful.
- Data can be arranged in order
Ex rank top 5, course grades (A, B, C), types of cars
18
Q
Internal Level of Measurement
A
- Quantitative data
- Differences between Data entries is meaningful
- Data can be ordered
- Zero represents a position on a scale (not an inherent zero - zero does NOT imply “none”)
Ex Temperature, years
19
Q
Ratio Level of Measurements
A
- Similar to interval level
- 200 entry is an inherent zero (implies “none”)
- A ratio of two data values can be formed
- One data value can be expressed as multiple of another
Ex weights, prices, precipitation, distances, rainfall, money
