A marine scientist observes that fish are found at higher concentrations closer to the coast of California than farther out in the Pacific Ocean. She concludes the fish populations are always large close to the coasts throughout all oceans. Why is this an invalid scientific conclusion?

a. She needs less data to draw conclusions.

b. Scientists should repeat this experiment at different sites to draw conclusions.

c. Scientists require laboratory-based experiments to draw conclusions.

d. Scientists always need long-term observations to draw conclusions.

Jayden · Answer 1

The correct answer is B.

Alfonso Stuart · Answer 2

Option B

Explanation:

When ever a scientific research or experiment is conducted, it is made sure that the results obtained are consistent through multiple trials. Here, only two trials are done i. e one on coast of California and the other on the Pacific Ocean.

Since the number of samples taken for this study are not as per the standard sample guidelines and hence the result obtained can not be considered as a acceptable.

Thus, option B is correct
