Q

Non- probabilistic (judgemental survey)

A
  • targeting specific areas by the excavator in a non- random manner
  • often used when the archaeologist is most interested in already visible or suspected sites
  • results cannot be extrapolated beyond that area, or used to generalize about non- sample; context within the study area

Q

Probabilistic (random) sampling

A
  • uses random sampling techniques to mathematically relate small samples of data to larger study areas by studying a representative sample of the whole area
  • makes generalizations derived from the sample for the entire area

Q

Simple random sampling

A
  • simplest form of probabilistic sampling
  • numbers are assigned to a grid, drawn over a survey area, and sampling units are selected in a completely random basis
  • the spacing between sampling g areas is often uneven
  • large parts of sampling g area may be left out of the sample completely, just by chance
  • strengths: east
  • problems: areas may be left out by chance, may be uneven coverage for

Q

Stratified random sampling

A
  • used when the survey area is not geographically uniform
  • the broader sample area is divided in ways that reflect observed variation within the area (ecological zones, activity areas, artifact classes)
  • each category is designated an amount of sample units proportional to its area
  • with each category/ division, the position of the sample units is determined by random sampling
  • weak spot: if you don’t have good categories than your study isn’t going to be good

Q

Systematic sampling methods

A
  • easy from planning and survey perspective
  • choose one unit at random, and then select others at equal intervals from the first one
  • sample units are evenly distributed
  • useful for surface collection where artifacts are visible in the ground surface
  • avoids areas of low sample concentration that can be a problem in simple random sampling
  • by may oversample/ miss every site if arky material also falls at regular intervals

    Stone look weights
  • don’t have evidence that they were living there for a long time
118
Q

Why did the settlement collapse (hypotheses)

A
  • overgrazing by cattle, erosion of fragile soils
  • attack by Thule
  • climatic change (global cooling, more sea ice)
  • refusal to adapt to local conditions
  • collapse of fur trade routes, falling ivory prices
  • overspending on luxury items (elite goods, church provisions)
119
Q

Mass spectrometry- isotope analysis

A
  • mass spectrometry used for a number of other isotopes
  • mass analysis tells you the relative amounts of different isotopes
  • climates
  • carbon (diet, radiocarbon dating)?
120
Q

Oxygen isotope analysis

A
  • measuring the difference between oxygen 18 to oxygen 16
  • sea water warm periods - relatively high oxygen 16
  • sea water cold - relatively high oxygen 18
  • allows track global temperatures
  • Greenland: right before abandonment sea ice building up
  • salt particles in ice cores suggest storminess rose toward end
  • carbon isotopes in bones show shift to a more marine diet
121
