Question

after completing four rounds of trials (repetition), scientists at dallas white enterprises found that three of the four fertilizers tested caused a significant overgrowth of cyanobacteria in water samples from lake erie. the experimental design and findings were published and sent to an environmental laboratory at a local university. their scientists repeated (replication) the experiments and received very similar results. select the statement(s) that accurately support why repetition and replication are essential to the scientific process. to ensure experimental data is accurate and reliable. to write articles and textbooks to help other scientists learn how to conduct experiments. to identify possible mistakes and errors in the experimental design

Explanation:

Repetition and replication help verify results, reducing random - error effects and uncovering design flaws, thus ensuring data accuracy and reliability. Writing articles and textbooks is a secondary outcome, not the main reason for repetition and replication.

Answer:

To ensure experimental data is accurate and reliable.
To identify possible mistakes and errors in the experimental design.
