ASM 275 EXAM 3 CERTIFICATION REVIEW
2026 QUESTIONS AND VERIFIED
SOLUTIONS GRADED A+
⩥ Nominal.
Answer: discrete and discontinuous data that are classified according to
some qualitative measure that cannot be placed in a specific order
⩥ ordinal.
Answer: discrete data that can be ranked, counted, and ordered, but not
measured
⩥ interval.
Answer: continuous scale data that are ordered, quantified, and with
exact differences between the values (it is known).
-0 does not mean the absence of the feature being measured, but instead
represents the arbitrary value.
⩥ ratio.
Answer: ordered, quantified, exact known differences between values.
-Has absolute value that is meaningful and not arbitrarily determined.
height , weight, head size that can be measured are ratio scale data.
, ⩥ accuracy.
Answer: is closeness of the measurements to a specific value
⩥ percision.
Answer: is the closeness of the measurements to each other
⩥ intra-observer error.
Answer: precision of data recorded by the same observer
-Humidity, lighting conditions, temperature, observer mood, and tool
failure/ calibration can increase this.
⩥ Inter-observer error.
Answer: error resulting in the accuracy of data recorded by different
observers
-Observer experience, use of measuring equipment that may be
calibrated differently, use of different measurement definitions, and
training methods can increase this
⩥ Metadata.
Answer: data that describes other data, doesnt relate
⩥ Incisors.
Answer: biting teeth in front - 8 total
