How calculate median of RT

Coding

Hello! Hope all are good!

I’m trying here to calculate de median of RT, but having some issues.
What I’ve tried?

Blockquote

At Begin Experiment
# importing statistics module
import statistics
At Begin Routine
median_latency = round(statistics.median(rt))
At End Routine
thisExp.addData('median_latency', median_latency)

This is the following error:
error_median_code

Hello

is rt a list?

Ok, there is one approach. Define a list that that stores the rt in the Begin experiment tab

rtList = []

In the End routine tab of the rt-trial insert

rtList.append(key_resp.rt)

Change key_resp.rt to the name of your rt-component. Add a routine following your rt-loop and insert the following a Begin routine tab

median_latency = np.median(rtList)
thisExp.addData('median latency', median_latency)

BTW, I used numpy instead of statistics for computing the median.

Best wishes Jens
