This implementation of a set of proper validation steps for detection of duplicates can

save the investigator a lot of time for removing duplicates. However, even with the

implementation of such proper validation steps for detection of duplicates, it is still

compulsory for the investigator to carefully screen for duplicates in the data set before

conducting the statistical analysis because we cannot be totally sure that the system would be

working as efficiently as we have expected them to.
