Measurement and Observation
Measurements and observations are best explained using an example.
The following shows a typical data table:
| Trait1 | Trait2 | Trait3 |
Species1 | tv11 | tv12 | tv13 |
Species2 | tv21 | tv22 | tv23 |
Species3 | tv31 | tv32 | tv33 |
Each cell of the table is a measurement, so this table has 9 measurements.
Each row of the table is an observation, so this table has 3 observations.
