Question

1. which of the following is a disadvantage of a controlled experiment? the effect of the variable is apparent. it does not replicate real world conditions. it is easy to repeat. the results are more valid.

Explanation:

A controlled experiment has limitations. One key drawback is that it often takes place in an artificial, controlled environment. This means it may not accurately represent the complexity and variability of real - world situations. For example, in a laboratory setting, variables can be tightly regulated, but in the real world, there are numerous interacting factors that cannot be easily replicated.

Answer:

It does not replicate real world conditions.
