Question

A zoology student is investigating whether it is true that the gender of turtles depends on the temperature at which the turtle eggs are kept before they hatch. He will test if turtle eggs incubated at 29–30 degrees Celsius produce females, and eggs at 24–26 degrees Celsius produce males. What is the independent variable?

Answer 1

There are two main variables here, the temperature vs the gender of the hatched turtles. The independent variable determines the change in the dependent variable. So in our case which one causes the change in the other? The temperature or the gender?
