accuracy

Raquel_Viula

Hello, I've just built a visual search test using OpenSesame for the first time. Would someone know where could be my mistake when I get max. 96,88% accuracy as the result of a test for which accuracy is actually of 100%? - i.e., I do everything correctly but the max I'm getting is that value.
Thank you.

Hi Raquel,

Could it be that your practice trials are included in the equation?
In any case, you also have the variable correct, which will always be a long column of 1's and 0's in your .csv file. You can calculate the accuracy based on that as well.

Cheers,

Josh

Hi Josh,

can you explain, how ich can calculate the accuracy based on correct in my file? Cause it´s a huge amount of datas it is not possible to do this by hand...

Hi,

In a spreadsheet program like Excel, LibreOffice or OpenOffice you can do this using a Pivot Table. To help you in a more precise way, we'll need to know what the independent variables / factors are in your experiment.
