What is the primary goal of sampling?

The primary goal of sampling is to obtain uniform representative samples that accurately reflect the characteristics of the whole population. This is crucial in various fields, including the asphalt industry, where understanding the material's properties is essential for quality control and production consistency. Random sampling helps to eliminate bias, ensuring that every part of the population has an equal chance of being selected. This approach enhances the reliability of test results and allows for meaningful analysis, which is vital for making informed decisions about the material being sampled.

Collecting samples that are of the same weight, gathering as many samples as possible, or strictly adhering to a sampling schedule may not address the critical aspect of representativeness, which is essential in providing a true reflection of the entire material lot. Random selection is key to achieving a reliable dataset, making it the main focus of good sampling practices.
