Q

The variogram may exhibit an apparent discontinuity at the origin. The magnitude of the discontinuity is called the:

A

nugget

28
Q

The variogram quantifies the:

A

spatial correlation

29
Q

A variety of kriging which assumes that local means are not necessarily closely related to the population mean, and which therefore uses only the samples in the local neighborhood for the estimate.

A

Ordinary Kriging

30
Q

Which statistical test is used to test for differences in the means of two or more groups?

A

ANOVA

31
Q

Which is an example of an ordinal level data?

A

Moh’s scale
