Which tool is commonly used to record data during data collection?

• A. Tally counter
• B. A ruler
• C. A GPS device
• D. A weather app

Answer: (A)

Recording data during data collection focuses on capturing how often a behavior occurs. A tally counter is designed for counting discrete events as they happen, making it ideal for frequency data. You can press the button each time the behavior is observed, and the device keeps a running total you can later transfer to a data sheet. This keeps your attention on the observed person or object and reduces the chance of losing track while you’re recording.

Other tools serve different purposes. A ruler measures physical dimensions, not event occurrences. A GPS device logs location, which isn’t the primary method for counting how many times a behavior happens. A weather app tracks environmental conditions, not the frequency of observed behaviors.
