Percentage of RecordsString/ExpressionActivates when you select Sampling Type is Percentage of Records for Sampling Type.

Enter the percentage number of records to sample your data based on a percentage value of the total records in the table.

Info
  • The number of records in the output is rounded off to the lower value if the percentage leads to a decimal. For example, if you enter 75 and if the table has 10 records, the output yields 7 records since 75% of 10 is 7.5.
  • The number of records in the output is randomized and is up to a maximum of the percentage calculation specified above. Therefore, in the above instance, the output may contain 5, 6, or 7 records.
