Question

Jimmy belleves that mice exposed to radio waves will become extra strong. He decides to perform an experiment by placing 10 mice near a radio for 5 hours. He compares these 10 mice to 10 different mice that have not been exposed. The test consisted of moving a heavy block of wood that blocked the mouse food. He found that 8 out of 10 of the radio waved mice were able to push the block away, while 7 out of 10 of the mice not exposed to radio waves were able to do the same. 4.What is the independent variable in this example? (2 pts.) 5. What is the dependent variable in this example? (2 pts.) You are doing an experiment on the habitat preference of red-eyed tree frogs. You want to determine if red-eyed tree frogs spend more time sitting in a tree or on the ground. Here is the data you obtained from your experiment. Time in tree (minutes) Time on ground (minutes) Frog 1 Frog 2 CON Frog 3 Frog 4 Frog 5 6. Using the data, construct an appropriate graph to adequately express your data (2 pts) 7. Label the axes (2 pts) and give your graph a descriptive title.(2 pts)

Answer 1

4. Independante varible is Radio waves becasue The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment.

5. Dependent variable is Mice: The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable.

Graph: Habitat Preference of Red Eyed Frogs 26 22 18 19 15 Time (min) T/Tree T/Ground Forg- Frog-II Frog-III Frog-IV Frog-V

the above mentioned graph reveals that, habitat preference of Red eyed Frog with refernce to the treea and ground.
