The results show that travel speed has a large range, but that the majority of the maggots reach the boundary of the circle within a small time range. The experimenters needed to establish whether there were any confounding variables that might have influenced the results.
Look at thire list of possible confounding variables and decide which possible confounding variable
From this statement which one is Possible
confounding variable
A) When the 10 maggots were released some were already pointing away from the light whereas others might have
had to turn round first.
B )Those that travelled away from the light might cross the circle at different places.
C) The light source might have been warmer than the surroundings.
D) Longer maggots might travel faster – a smaller number of body-length equivalents to travel.
E) Maggots might be of different ages.
F) The observers might have been expecting a particular result.
