<h3><u>What is bias in sampling?</u></h3>
When a sample is chosen in statistics, sampling bias is a bias that causes some individuals of the target population to have a lower or greater sampling probability than others. As a result, not every person or event was equally likely to have been chosen, resulting in a biased sample of a population (or non-human variables).
If this is not taken into consideration, results may be incorrectly attributed to the sampling procedure rather than the phenomenon being studied. Although some people identify sampling bias as a distinct sort of prejudice, sampling bias is typically categorized as a subtype of selection bias, sometimes referred to as sample selection bias.

Difference between Floor inspection and Functional inspection.
• Floor inspection is usually conducted in a production environment. It involves checking of materials while processing in the machine by inspectors. Rather than checking the materials in the machine at the beginning of production, floor inspection checks the materials while in process inorder to ensure that the defected ones are quickly detected and expunged. It also ensure that the equipments used in processing are properly functioning.
• Functional inspection is an inspection that checks the overall function of a product rather than what makes up the component parts. For instance the load capacity and speed of a vehicle can be checked for optimal performance whereas individual parts that make up the vehicle are not checked, yet bring out satisfactory performance when combined together. This form of inspection is concerned with verification of final output and does not provide details about different sections instead provides a wider understanding of comfort that emanate from inspecting same item.
Points of Convergence between Floor inspection and Functional inspection.
