### Sample Dialog

You can reduce the number of concordances down to a more managable set using one of two different methods:

#### Every Nth

The computer picks lines in equal intervals, in order to get a fair spread over the data. The size of the interval is calculated from the proportion of total data size and target size; with 500 lines being reduced down to 100, every fifth line would be selected. This method is stable, ie you can repeat its result when applying it to the same data again.

#### Random

The computer selects lines randomly. Unlike the previous method, it is not possible to repeat this, ie you will get a different set each time you try it on a set of data.
