Document Summary
Process of detecting and correcting coding errors in a machine-readable dataset. Process of checking to see that only the codes assigned to particular attributes (values of possible codes) appear in data files. Under the variable gender, 1=female, 2=male, 3=no answer; if the number 7 is entered, this will be an error and has to be changed. Checking that only those cases that should have data entered for a particular variable to do in fact have such data. The examination of the distribution of cases of only one variable. Description of the number of times the various attributes (values) of a variable are observed in a sample. A report that53% were men and 47% were woman. Often laid out in a table, recording the number of cases observed for each of the attributes of some variable. Ambiguous term suggesting typical or normal central tendency. Jumps from category to category, intervening steps wouldn"t make sense.
