The given code snippet calculates the average value of the tally column from the dbo_remark_dpgmodel_seg_stats table, and aliases the result as AvgOftally.

Here's a breakdown of the code:

• Avg(...): This is an aggregate function in SQL that computes the average (mean) of the values in the specified column within a group of rows. In this case, it is calculating the average of the tally column.
• dbo_remark_dpgmodel_seg_stats.tally: Specifies the tally column in the dbo_remark_dpgmodel_seg_stats table.
• AS AvgOftally: The result of the calculation is given the alias AvgOftally, so you can refer to it in the output by this name instead of the full calculation.

Example:

Suppose the tally column in the dbo_remark_dpgmodel_seg_stats table contains the values [10, 20, 30]. This query would compute the average of these values:

[ \text{AvgOftally} = \frac{10 + 20 + 30}{3} = 20 ]

The output will be a single value (20 in this example) labeled AvgOftally.
