Advantages of Consecutive Sampling In consecutive sampling technique, the researcher has many options when it comes to sample size and sampling schedule. Both of these sampling techniques are similar and often used interchangeably, but the difference is that consecutive sampling tries to include all accessible subjects as part of the sample.

This type of sampling can be used when demonstrating that a particular trait exists in the population. This can be quick to do when the chain of members develops past the first few levels. Consecutive sampling: Researcher selects a sample or group and after data collection and analysis moves to another sample Non-probability sampling methods . However, both types of sampling techniques have differences in their processing. A null hypothesis means a statistical theory in which no significant difference exists between the set of variables involved in the research or experiment. Consecutive sampling is a common method of data collection used to study a specific group of individuals. Also, as the ideal candidates will have similar traits, once you understand where to attract them from, you can repeat the process until you have the sample size you need.
