Choosing the right word
  • 追試ついしCommon

  • 反復はんぷくCommon
    noun, suru verb, transitive verbA broad word for 'replication' as repetition or doing something over again. It lacks the specific nuance of verifying experimental results, so it is not the natural choice for the experimental sense of the English word.

Use 追試 when 'replication' means repeating an experiment to verify its results, and 反復 when it refers to repetition or replication in a general or technical sense.
