Woodlice Turn Alternation
You want to determine whether woodlice show turn alternation behaviour, that is when given a choice immediately after a forced turn they will turn in the opposite direction. In this experiment the woodlice are given a choice of direction to turn after a forced right turn:
Note: These data are in their “tallied” up form (see starting point). You should be able to copy and paste these data into the spreadsheet in this toolkit to perform the test.
| Direction turned when given free choice after forced right turn | Number of Woodlice (Observed Frequency) |
|---|---|
| Turn right | 47 |
| Turn left | 153 |
Expected frequencies are equal (100)
