ISSN Print: Pros and cons of different sampling techniques

A method of sampling that involves the division of a population into smaller groups known strata. In stratified random sampling, the strata are formed based on members shared attributes or characteristics. A random sample from each stratum is taken in a number proportional to the stratum’s size when compared to the population. These subsets of the strata are then pooled to from a random ...

Mining Geology Sampling Methods: Channel, Chips, Core

The simple equipment needed for hand-dug sample pits or shafts is a particular advantage in remote areas or where only a limited amount of sampling is anticipated. A few strategically located pits or shafts may show that the ground is entirely unfit for mining or that it will not warrant the expense of drilling. On the other hand, if they return good prospects and the ground is subsequently drilled, the expense of

chosen using probabilistic methods, stratified random sampling allows us to make generalizations (i.e. statistical inferences) from the sample to the population. This is a major advantage because such generalizations are more likely to be considered to have external validity. Cons of Stratified Sampling

Nonprobability sampling is a collection of methods that do not rely on formal random techniques to identify the units to be included in the sam-ple. Some nonprobability methods include judgment sampling, conven-ience sampling, and purposive sampling. (11 judgment sampling representative units of the population are se-lected by the investigator. In convenience sampling, the sample is

03/03/2020  List of the Advantages of Systematic Sampling. 1. It is simple and convenient to use. Researchers can create, analyze, and conduct samples easily when using this method because of its structure. The algorithm to make selections is predetermined, which means the only randomized component of the work involves the selection of the first individual. Then the selection process moves
