How are tally marks used to record data for a survey?

Tally marks are a simple method used to record data in surveys by representing each response with a vertical line. For every occurrence of a specific response, a mark is drawn; every fifth mark is typically drawn as a diagonal line crossing the previous four to group them for easier counting. This visual representation allows for quick counting and comparison of responses. Tally marks are particularly useful for small datasets and can be easily tallied in real-time during data collection.
