What if your friend tells you that the stimulus of music makes his goldfish swim faster How would you design a controlled experiment to test your friend's claim?

To design a controlled experiment to test your friend's claim, you could set up two identical tanks with goldfish. In one tank, play music as the stimulus, while keeping the other tank silent as the control. Measure and record the swimming speeds of the goldfish in both tanks over a specific time period. Repeat the experiment multiple times to ensure reliability and consider variables such as the type of music, volume, and duration of exposure. Analyze the data statistically to determine if there is a significant difference in swimming speeds between the music-stimulated goldfish and the control group.
