True or False: Generally, small samples are most representative of the total supply.

Sampling for materials such as aggregate requires careful consideration of how well a small sample represents the larger population of material being tested. The correct understanding is that small samples are typically not representative of the total supply because they may not capture the variability and characteristics of the entire quantity of material.

In aggregate sampling, larger samples are more likely to include a variety of particles, sizes, and compositions, which leads to a more accurate reflection of the overall material properties. Small samples can introduce significant errors due to the limited number of particles, which might not adequately showcase the diversity and variability present in a larger volume of aggregate.

Correct sampling practices often involve taking larger and well-distributed samples to minimize the risk of misrepresentation. Factors such as segregation, moisture content, or other physical properties can also influence how well a small sample reflects the entire batch. Therefore, stating that small samples are usually most representative is misleading and incorrect.
