The consecutive sampling technique gives the researcher an opportunity to study diverse topics and gather results with vital insights. Probability sampling techniques require you to know who each member of the population is so that a representative sample size can be chosen. In contrast with probability sampling, non-probability sample is not a product of a randomized selection processes. Advantages of sampling Sampling ensures convenience, collection of intensive and exhaustive data, suitability in limited resources and better rapport. Proportional quota sampling gives proportional numbers that represent segments in the wider population. List of Cons of Convenience Sampling 1. It doesn't take much effort to start a convenience sampling effort.

The researcher does not consider sampling bias. gives the researcher a chance to work with multiple samples to fine-tune his/her research work to collect vital research insights. By allowing a group of non-traditional sample members to explore a topic, the insights will be unique and unpredictable, meaning that this could be valuable for thinking outside the box. Here are the four advantages of consecutive sampling In a consecutive sampling technique, the researcher has many options when it comes to sampling size and sampling schedule. Non-probability sampling techniques are a more conducive and practical method for researchers deploying surveys in the real world. [2] Bias can also occur in consecutive sampling when consecutive samples have some common similarity, such as consecutive houses on a street.[5]. Possibility of Sampling Error The target population is the total group of individuals from which the sample might be drawn. If a researcher is unable to obtain conclusive results with one sample, he/she can depend on the second sample and so on for drawing conclusive results. To achieve this, you are going to ask every student to stand up, one at a time. Here is where sampling bias comes into the picture.
