# Workshop 1 – Skalenniveaus Melbourne Housing Dataset
|
||||
|
||||
## Klassifikation der Variablen
|
||||
|
||||
| # | Spalte | Dtype | Skalenniveau | Bemerkung |
|
||||
|---|---|---|---|---|
|
||||
| 0 | Unnamed: 0 | int64 | nominal | CSV-Index, reine ID – für ML droppen |
|
||||
| 1 | Suburb | object | nominal | hohe Kardinalität, Encoding-Strategie nötig |
|
||||
| 2 | Address | object | nominal | Kardinalität ≈ n, für ML ungeeignet |
|
||||
| 3 | Rooms | int64 | metrisch | Zähldaten, Ratio-Skala |
|
||||
| 4 | Type | object | nominal | h/u/t – wenige Kategorien, One-Hot |
|
||||
| 5 | Price | float64 | metrisch | Ratio-Skala, typische Zielvariable |
|
||||
| 6 | Method | object | nominal | Verkaufsmethode |
|
||||
| 7 | SellerG | object | nominal | hohe Kardinalität |
|
||||
| 8 | Date | object | metrisch | formal Intervall, dtype sollte datetime sein |
|
||||
| 9 | Distance | float64 | metrisch | Distanz zum CBD, Ratio |
|
||||
| 10 | Postcode | float64 | nominal | trotz numerisch – keine sinnvolle Ordnung |
|
||||
| 11 | Bedroom2 | float64 | metrisch | Zähldaten, alternative Quelle zu Rooms |
|
||||
| 12 | Bathroom | float64 | metrisch | Zähldaten |
|
||||
| 13 | Car | float64 | metrisch | Anzahl Parkplätze |
|
||||
| 14 | Landsize | float64 | metrisch | Ratio-Skala |
|
||||
| 15 | BuildingArea | float64 | metrisch | Ratio-Skala |
|
||||
| 16 | YearBuilt | float64 | metrisch | formal Intervall |
|
||||
| 17 | CouncilArea | object | nominal | Verwaltungsbezirk |
|
||||
| 18 | Lattitude | float64 | metrisch | formal Intervall, mit Longitude als Paar behandeln |
|
||||
| 19 | Longtitude | float64 | metrisch | formal Intervall, mit Latitude als Paar behandeln |
|
||||
| 20 | Regionname | object | nominal | wenige Kategorien |
|
||||
| 21 | Propertycount | float64 | metrisch | Anzahl Properties im Suburb |
|
||||
|
||||
## Anmerkungen
|
||||
|
||||
- `Date` und `YearBuilt` sind formal Intervallskala (kein echter Nullpunkt),
|
||||
werden hier aber zu metrisch zusammengefasst, da die Klasse Intervall/Ratio
|
||||
nicht weiter unterscheidet.
|
||||
- `Postcode` ist trotz `float64`-dtype nominal – Postleitzahlen haben keine
|
||||
sinnvolle Ordnung. Float entsteht durch Missing Values.
|
||||
- Geokoordinaten passen streng genommen nicht ins Stevens-Schema
|
||||
(zyklisch, nicht-euklidisch), werden pragmatisch als metrisch geführt.
|
||||
- `Address` und `SellerG` haben sehr hohe Kardinalität → Kandidaten für die
|
||||
Liste ungeeigneter Variablen in Workshop 2.
