    Area of Science:

    • Environmental science
    • Statistical analysis
    • Sampling methodology

    Background:

    • Composite sampling is standard for materials like fertilizer bags and water for plankton density.
    • It involves mixing several samples into one composite sample for analysis.
    • Existing methods by Brown and Fisher [1972] are limited to simpler scenarios.

    Purpose of the Study:

    • To extend composite sampling statistical methods.
    • To address more complex sampling situations with multiple variance components.
    • To enhance the analysis of population characteristics from composite samples.

    Main Methods:

    • Extending the statistical framework of Brown and Fisher [1972].
    • Developing methods for situations with more than one variance component.
