Question

In experiments, repeated trials help the researcher obtain more _______.

1) variables
2) cost-effective data
3) time per group
4) representative data

Answer 1

Repeated trials in experiments are critical for obtaining more representative data, as they increase the validity and reliability of the results by minimizing random chance and potential errors.

Step-by-step explanation:

In experiments, repeated trials help the researcher obtain more representative data. Repetition, or replication, of an experiment increases the validity of the results by ensuring consistency. With each additional trial, the confidence in the experimental findings strengthens because it minimizes the effects of random chance and allows for more accurate measurement of the effect of the independent variable. It is a fundamental aspect of the scientific method and helps to eliminate or reduce potential biases or errors that might skew the results. Thus, the answer to the student's question is that repeated trials in experiments help to obtain more representative data (option 4)
