Question

Large sample sizes are always better but sometimes the cost is prohibitive; thus you must always weigh the statistical benefits of collecting more data.

1) True
2) False

Answer 1

Larger sample sizes are generally better in scientific experiments, but the cost can be prohibitive. Researchers must weigh the statistical benefits of collecting more data.

Step-by-step explanation:

The statement that larger sample sizes are always better but sometimes the cost is prohibitive, so you must weigh the statistical benefits of collecting more data, is true.

While larger sample sizes generally provide more accurate and reliable results in scientific experiments, the cost of collecting larger samples can be a limiting factor. Therefore, researchers must consider the trade-off between the benefits of larger sample sizes and the associated costs.

For example, in crash testing cars or medical testing for rare conditions, small samples may be unavoidable. However, even with small samples, it is still possible to draw conclusions by properly analyzing and interpreting the data.
