What does a minimum-to-maximum range leave out about a performance sample?
A minimum-to-maximum range identifies the lowest and highest observed values in a defined sample. It does not show how many observations cluster near either endpoint, how values are spread between them, or whether there are gaps. Two samples can share the same endpoints and have very different distributions. Read the range with the metric, units, sample size, and appearance window; it is a description of recorded history, not a forecast.

The endpoints do not describe the middle
A range is useful for seeing the observed extremes, but it compresses every interior value into two endpoints. It cannot tell you whether most observations were close together or whether they were split across distinct clusters. It also does not show which observation occurred first.
- Confirm the exact metric and unit before comparing ranges.
- Keep the selected sample window and number of appearances visible.
- Use the underlying observations or another summary when distribution matters.
Identical endpoints can hide different patterns
A sample with many values near its minimum and one value at its maximum can have the same range as a sample with values spread more evenly. The endpoints alone do not distinguish those cases. If the middle affects the question, inspect the full sample or a clearly named additional summary rather than inferring a pattern from the range.
State what the range covers
A useful report names the subject, metric, unit, cutoff, and included appearances. If one observation is missing or excluded, record that limitation. Do not present an endpoint range as though it were the full distribution or the expected next value.
Hypothetical example: the same endpoints, different distributions
For illustration only, compare two invented ten-value samples in generic units. Sample A is 2, 2, 3, 3, 4, 4, 5, 6, 7, 10. Sample B is 2, 2, 2, 2, 2, 2, 2, 2, 10, 10. Both have a minimum of 2 and maximum of 10, yet most middle observations differ. The shared endpoints do not tell you which pattern occurred in a real record. These are synthetic values, not sports-performance data.

Does a range tell me how often the minimum or maximum occurred?
No. The endpoints identify the lowest and highest values, but frequency requires examining the observations or a separate count.
