Planning a Practical Investigation

Postby AG1995 » Wed May 03, 2017 9:25 pm

Hello,

I am about 3/4 of the way through this assignment and I'm really enjoying it. I just have a question concerning recording data. For the pulse measurements, what tool would be used to record these? I know I am probably overthinking this massively.. but for example, for recording the amount of times someone flinched during a horror movie, you would use a frequency chart. Or for rating levels of fear, a rating scale. What would you use to record a pulse on 3 occasions during an experiment? My mind has gone blank!

Thank you!

Hi
I have seen people use apps on their phones that take pulse rate, oximeters (if they have been able to borrow them) but most people just use a stopwatch
Hope this helps, glad you are enjoying the assessment! :thumbup:

Smart and simple way is to use oximeters, they are quick and accurate
