§ 67.17 – What steps should I take after I have identified and corrected errors in my data?

(a)    You should stack the corrected sample data from the field as shown in Table 67.01 in one or more worksheets.  These worksheets along with the survey sheets become an auditable record of your sample data.

(b)   You should enter the summary data at the level of your unit of sampling and measurement in a separate worksheet.  These summary data are ready for developing new sampling plans or for estimating service-consumed data for the NTD.

(c)    Table 67.09 shows how that summary worksheet looks with the column headings and the summary sample data for one service unit.
