Question

This is hard, Please help, medal n fan(;
Raychelle did an investigation to see how the amount of nitrogen in pond water affects the number of trout in the water. She tested the water of 20 different ponds. Each one had a different amount of nitrogen in it. She then did a study to determine the number of trout in each pond and compared the amount of nitrogen to the number of trout in each pond. What was Raychelle's dependent variable?
Select one:

a. the number of trout in each pond
b. the number of ponds in her study
c. the amount of nitrogen in each pond

Answer 1

im thingking a or c, idk

Answer 2

remember the dependent variable is the thing you measure...

Answer 3

oh duhh. Its B then.(;

Answer 4

this one is tricky. She will need to know the amount of nitrogen in each pond, but that is then the dependent variable. So the answer is actually a). This is because the amount of nitrogen affects the number of trout (or so her hypothesis should say!). So the amount of trout is dependent on the amount of nitrogen. Sorted?

Answer 5

Gosh,these dependent and independents always screw me up.
so its A? because the fish are dependent on the levels of nitrogen?
