What is transect sampling?
Transect sampling is a method used in ecological studies to assess the distribution and abundance of species within a specific area. It involves laying out a predetermined line or path, called a transect, across a habitat and systematically sampling at regular intervals along this line. This approach helps researchers collect data on various ecological parameters, such as plant density or species diversity, while minimizing bias and ensuring that the sampling represents the overall environment. It's particularly useful in studying gradients or changes in ecosystems, such as those influenced by environmental factors.
What about accidental sampling?
Accidental sampling is a type of nonprobability sampling which involves the sample being drawn from that part of the population which is close to hand. That is, a sample population selected because it is readily available and convenient. The researcher using such a sample cannot scientifically make generalizations about the total population from this sample because it would not be representative enough. For example, if the interviewer was to conduct such a survey at a shopping center early in the morning on a given day, the people that he/she could interview would be limited to those given there at that given time, which would not represent the views of other members of society in such an area, if the survey was to be conducted at different times of day and several times per week. This type of sampling is most useful for pilot testing.
