Item Statistics

As you enter observations in a single item several statistics are updated automatically once the focus leaves the cell you are editing.

The last 3 columns in the observations table are read-only and they are calculated by DET itself. They are coloured in grey to distinguish them from user-editable fields.

Autocalculated Item values

For each observation the following values are calculated:

• Price
• Price Ratio
• T - value

On the top right of the screen the DET also displays item level statisticts:

Item level statistics

These are :

• Average price
• Minimum price
• Maximum price
• variation coefficient
• Net price
• If the item is questionable or extremely questionable
