Data acquisition
Two routines or protocols can be used.
Data analysis
The acquisition and analysis program that we are using (EthoVision v.3.0) converts the video image of your tracked object into a series of <x, y> coordinates producing a layout of the spreadsheet. The Analysis module turns these coordinates into parameters able to be introduced in final statistical and graphics software for your publication.
Output Parameters
A ranges of dependent variables (parameters) as well as descriptive statistics of the parameters are the output of the analyzed data Your data will be exported to a spreadsheet or statistical program of your preference to perform statistical tests on your data.
