Correct or exclude a result

When a value is wrong, correct it. The original stays on record and you do not need to give a reason. When a value must not be used, exclude it with a reason, and the row stays in the study. About records and history explains why both work this way.

Each row's Correct / exclude button reads Edit, Corrected, Excluded or Fix errors. Fix errors marks a problem that stops the calculation. Select the button to open Correct or exclude row n. For a flagged row, the dialog states the problem beside the affected field and places the cursor there. Error links above the grid take you directly to the affected cell. The dialog shows the Original entry (and the row's specimen ID and where it came from) and editable result and design fields, including level and replicate. The file name and source row identify an imported entry. Paired studies such as method comparison have two value fields.

The original is the value in the imported file, or the first value saved for a typed row.

1. Open the row dialog.
2. Enter the right value in the affected result or design field. The number fields show the study's decimal convention.
3. Select Save row changes (or press Enter in a text field), then save the study.

You can also change a value in the grid itself. Either way the original value stays on record beside the corrected one.

1. Open the row dialog.
2. Tick Exclude this row from the calculation.
3. Enter an Exclusion reason, for example Clot flagged by analyzer. Without one, the dialog says Enter an exclusion reason.
4. Select Save row changes, then save the study.

An imported file can set exclusions too, through Excluded and Exclusion reason columns. See also rows without a value.

To include a row again, untick the box and recalculate.

To leave a saved row out of the calculation, exclude it with a reason. It stays in the study's record. An empty typed row can be removed from the notice above the grid. To start over, import again with Replace the current rows. See importing a file.

Results gives the counts, for example 19 results analyzed · 2 excluded. In repeatability, multi-day precision, bias and descriptive studies, a folded list under the results plot, such as 2 excluded results · review values and reasons, names the excluded results and their reasons. Select one to open its row in Data. The plot draws excluded results as crosses; they don't count in any statistic.

The report's data listing has every row. A row whose value changed shows its original and current values, Included reads Yes or No, and the reason for an exclusion appears in the Note column or, when reasons are long, as a numbered note under the listing, for example Study row 5: Excluded: Clot flagged by analyzer.

To practise on example data, follow Correct and recalculate.
