5. Brenda grew tadpoles in cages in 3 ponds and at two food levels (2 g food per L water and 0.2 g food per L Water) within each pond. Within each combination of pond and food level (each combination is considered a treatment), she had 3 replicate cages. She began the experiment with 100 tadpoles in each cage and at the end of the experiment she measured the body mass of each tadpole and the proportion of tadpoles surviving in each cage. What are the dependent variables? Survival, body mass What are the independent variables? (also called factors) pond, food level Now many experimental treatments did she have? __(hint each tadpole is reared or grown in a single treatment.) How many replicates did she have within each treatment? _ Should Brenda make inferences from her experimental results about the growth of tadpoles that would be raised at a food density of 3.0 g food per L water? Yes/No and explain briefly:

Solution

Since a combination of food and cage is considered as treatment so there are 6 possible combintaions are possible with 3 ponds and 2 food level. So she have 6 experimental treatment.

------------------------

Since she have 100 tadpoles in each cage so she have 100 replicates within each treatment.

-----------------------

No, she can compare the growth of tadpoles with two food levels 2.0 g per L water and 0.2 food levels per L water. She cannot make inferences from her experimental results about the growth of tadpoles that would be raised at a food density of 3.0 g food per L water.
