Validating and saving your work

As you enter observations on the items of the survey the DET automatically checks and validates the values you type. The most common checks are for ranges. For example, the value you enter for the collection month of an observation must be a number between 1-12. The DET will automatically warn you if an invalid value is entered.

Several statistics are also calculated on the fly by DET. These include observations statistics such as Price Ratio or item statistics such as Average Price.

Most importantly the DET keeps track of all questionable or extremely questionable items that appear according to the crucial values of the survey.

Once you save your work (as in any other document based application) you can safely close the DET. Upon restarting the DET, the last servey you were working on will be automatically loaded, so that you can continue entering observations as before.
