On the other hand, non-random sampling methods include accidental or convenient sampling and purpotive non-random sampling.Choosing whether to use probabilistic research sampling or non-probabilistic research sampling methods depends upon some factors. Some of the factors include period for the research, the sample size, workforce, nature of the research and the amount of cash. These factors will make a researcher to employ one of the methods or both of them at some different points. For time to be involved in the research, a researcher does have a limited time within which the work should be done and submit it. This period may be long enough to enable him or her employ random research or can be short for him or her to randomize. If there is enough time, the person can go through all the population and get a clear view of the whole unit. With short research periods, only select a few units in non-randomization to save on time.Sample size is also a factor that determines the sampling method that one uses. There are over sized sample units and undersized sample units. When a sample unit size is very large, it is almost impossible to use random sampling because it is tedious and time consuming. Such a population should be non-randomized for efficiency. A big sample size may include large organizations, a bigger population of people, students from one region, animals within a game reserve or plantations within a region. In such cases then it is wise to use non-randomized selection. However, when the sample space is small, divide it up into manageable units and then employ randomized sampling.Workforce means the amount of support staff in the whole exercise and the amount of work in the entire exercise. This involves those people that a researcher sends to the field to collect the data and interview the population. If the taskforce has few people then they cannot use randomized research in a sample field that is large and comprises of many sample units. This will force the researcher to adopt non-randomization because the workload will be manageable with the available taskforce. Before a researcher decides which method o use in data collection, he or she should consider the amount of work and the taskforce he or she has in place to help in the research process.The most important factor that is out in
