Flawed Data Entry. |
One field in the Reply Table indicates if the data entry is VALID or INVALID. On submission all data is declared as valid. If a submission is made without selecting an option or declaring a value, the reply is recorded for the quiz number by the subscriber but the reply is not used in any calculation or summary. If an unintentional option or value is selected, then the submission is recorded as a valid entry. After detection as an outlier or a notification by the participant that the data was erroneous, QAP-online may elect to leave the data as submitted but mark the record as INVALID. An invalid reply is excluded from calculations of variance and is excluded from any end of scheme estimates of bias or goodness of fit. The data set used in any calculations are always available (on most computers) as a table that may be posted into an Excel spreadsheet. The Invalid Data entry is highlighted in red and marked Invalid. The result on the participants summary tables are also marked as invalid. | ||||||
