Random selection ensures that every item in the population has an equal chance of being selected, and the person selecting the sample has no control over which items are chosen. Systematical selection involves selecting items at regular intervals, such as every 10th item on a list, which can still be influenced by the person selecting the sample. Haphazard selection involves choosing items based on convenience or without a clear plan, which can also be influenced by the person selecting the sample. Selection based on professional judgment involves the person selecting the sample using their own knowledge and expertise, which can heavily influence the items selected.
