Q

Nominal Level of Measurement

A
  • Qualitative data only
  • No mathematical computations can be made
  • Categorized using names, labels or qualities
    Ex SSN, colors, yes vs. no
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
