IOA and rate calculations #213

Open saraewise opened 5 years ago

saraewise commented 5 years ago

I just started using BORIS to code recorded videos for a research project with human subjects. I want to start by saying that this program is amazing! We used to use BDataPro, which is fine but clunky, and it doesn't have a video viewer built in or rewinding/editing capability (this means using a separate computer to watch videos and having to recode an entire session if you miss a key). I'm trying to get the rest of the team on board to use BORIS instead, but I'm still working on making it feasible for our purposes.

There are a few things that I think would make this program better for us (my apologies if BORIS already has these capabilities and I just haven't figured them out yet). Some of these features have already been suggested by others, including the ability to have a set observation time (e.g., 5-minute sessions) and to count point events that occur only during a specific state event.

Other features I would appreciate:

Thank you!

Other features I would appreciate:

  • calculation of interobserver agreement (IOA)--BDataPro automatically calculates IOA using 10s partial agreement, and I think this is the norm for reliability estimation in my field
  • calculation of rate per minute of point events in the time budget analysis

Thank you!

The IOA is already implemented (see IRR - Cohen's kappa). You can choose the time interval for agreement determination.
