Question

Each student repeated an experiment, and the results were pooled. What are the advantages of collecting a large number of results?

A) To decrease the accuracy of the data.
B) To minimize the time required for data collection.
C) To reduce the need for statistical analysis.
D) To increase the reliability and representativeness of the data.

Answer 1

Collecting a large number of results in an experiment increases the reliability and representativeness of the data, reduces variability between samples, and allows for more statistical analysis.

Step-by-step explanation:

Collecting a large number of results in an experiment has several advantages. One advantage is that it increases the reliability and representativeness of the data. This means that the data obtained from a large sample size is more likely to be accurate and reflective of the entire population. Another advantage is that a large sample size reduces the variability between samples, making the results more consistent and reliable. Additionally, a large sample size allows for more statistical analysis to be performed, providing more robust and meaningful results.
