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

The independent variable is the temperature. Independent variable refers to the  variable in an experiment that can be changed by the scientists or the one making the experiment. A good experiments has a single independent variable and the changes observed will be the dependent variable. In this case, the dependent variable is the gender of the turtle.
