Astudent does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. the student keeps a cricket in an enclosed box that is heated to different temperatures each day for twelve days. the student records the cricket’s chirps by using a sound-activated microphone so the timing of the chirps can be measured. which is the dependent variable in this experiment?
a)size of the box
b)temperature of the box
c)timing of the cricket’s chirps
d)volume of the cricket’s chirps

b

Explanation:

ye

The dependent variable in this experiment is C: timing of the cricket’s chirps.

Explanation:

The independent variable can show different values that do not depend on another variable. Instead, they directly affect the values of the dependents ones.

During an investigation, a researcher can study, under controlled conditions, how one of the variables influences the other one. The independent variable can be manipulated by the researcher, while the dependent one can not. A hypothesis is a claim of how it works this relation.

In the example, the relation is given by how temperature affects the timing of a cricket’s chirps. So "temperature" is the independent variable and "timing of a cricket´s chirp" the dependent one. Controlled conditions are the size of the box and the temperature degrees in the box. The volume of the cricket’s chirps could be a dependent variable but it was not measured in this experiment.
