Proceedings
No slides today – discussed statistical datatypes, after a working session between Dan and Elisa yesterday on this:
- Finite population – a population for which it is possible to count its units
- Mean – the average of a set of numbers
- Arithmetic mean - (Lucy)
- Geometric mean - (Lucy)
- Total – sum of the values for some characteristic of all units
- Index – the change in some aggregate relative to the value of the aggregate at a reference period (Best to ask Lucy)
- Ratio – result of dividing one measure by another
- Statistical datatype families:
- Nominal – unordered named categories
- Ordinal – nominal categories that are ordered
- Interval – quantitative data where differences between values are meaningful
- Ratio – interval data where a value of zero means absence of the quantity measured
- Unit of measure – a definite magnitude, established by convention, and used as a standard for measurement (modified from Wikipedia)
