An electrician wants to know which wire brand contains the least resistance. She runs 120 volts through 10 meters of 5 different wires and measures their output. They determine that brand C has the lowest resistance because it has the highest average out after 30 trials.
Independent Variable
Type of wire
Dependent Variable
Wire electrical output
Control
Wire length
Conclusion
Brand C has the lowest resistance
Hypothesis
If a wire has a higher electrical output, then it has a lower resistance
In the following experiment what is the control group?
A scientist want to know if lizards shed more when given a higher protein diet. They use 20 green anole lizards in 5 groups of 4 and give them diets with varying amounts of protein. Group 1 got the usual lizard food and every group after that got lizard for with increasing amounts of protein by 10 g. They determined that more protein does make green anole lizards shed faster because the group with 40 g extra protein shed the most on average.
