Test Sub-page for Grid Sampling

This sub-page of the Data Analysis page displays results of specific tests on the data values from the Data Entry Sub-page.

This page contains the following controls / displays:

Contamination Grid

VSP compares each data value against the threshold (action level) and counts the number of values that exceed the threshold. If the number of values that exceed the threshold is more than the number allowed for the specified test, then the null hypothesis that the site is dirty is accepted.

Refer to the main design test pages to determine how many exceedances are allowed for the test:

Acceptance Sampling

Compliance Sampling (Schilling method)

Bayesian approach to Show No Contamination (Wright-Grieve method)
