Sampling method





Biostatistics or mathematics quality assurance testing method Sampling plays an important role Sampling is a mathematical modeling method, with the help of one person from the mathematical population. The characteristics of a sample of statistics selected for the whole population are being studied. Sample data collected for statistics The sample is represented in the form of a questionnaire for the sample with two advantages (1) low rate (2) Immediate data collection After this internal population measurement is done. Each is reflected in the data collected by samples. Where one or more areas are found such as weight, location, color, etc. The Oversight Body can be identified independently and individually. In survey samples, weights are applied to the data that prepares the sample design



Definition of People

Defining a certain number of people is understood by the char set and all people and terms. Defining population means any terms and demographics selected for sampling Practical use Used in sample form.



Sample Framework

Before the sampling method, we must design a sample frame This is the main sample case of a rotating frame. e.g. a sample frame obtained from items that affect the population in the sample frame. Before taking a sample, a design framework should be developed during an individual survey. The color frame is the number of people with the help where the property of each item can be seen. Under everyone can be our sample.



Types Sample Method

Sample methods are usually of two types


A. Possible Sample Method

In this sampling method, all members included in the calculation have a choice. If you produce the result. If you want to make a presentation of all the mathematical work is considered, for this reason, it is necessary to make a sampling of the possibilities. If you produce the result.

Types of Possible Sample Methods

There are basically four types of possible sampling methods.



1. Easy Random Sample

In this case, all members of the public have an equal opportunity to choose This type of sample can be selected in the form of generators and other strategies in the form of tools. Feet of opportunity for all members of the public during the sampling process



For example, if we want to select 100 employees in the form of a random sample, we have to specify the total number of employees. We will use random number generators to select 100 numbers listed in 1-1000 on the company's website.


2. Formal Sample

The formal sample is similar to the random sample, but it takes a smaller sample to make this sample. Although this is not the case for random sampling, if you are going to use this process it is therefore important that we should make sure that there are no hidden members of the sample pattern. And its listing is required. For example, when a team is determined by a team employee on a staff database. So the top order for each group member has been entered.



3. Stratified Sampling

This sampling method is suitable for people with mixed characteristics If you want to know about the Avery members feature. So the stratified sample method used for Avery's characteristics, in this case, is equal to the sample. Represented in the sample in this way the population is divided into smaller groups. Based on the appropriate character Like gender, age, scope, income, brakes, occupation, etc.

By overcrowding, we can determine how many members in each small group are selected from the sample. After this, random and stratified samples can be taken to select a sample for all groups.



4. Cluster Sampling

Group sampling is studied under the opportunity sampling method. Group sampling is involved in dividing people into smaller groups. But each subgroup has the same characteristics and characteristics of complete samples If probability sampling is done practically, then this sampling method is possible, this sample can be combined from one person to another sample. If the owner of a large collection, individual samples can be taken within each collection. In this case, any type of sampling method that may be considered. This method is suitable for most people and is widespread. But in this way, there is a high probability of error in the sample



B. Non-Opportunity Sample Method

In this method, random conditions are selected from the non-probability sample. And not everyone has the opportunity to be selected In this type of sampling, it is easier and cheaper to collect a sample, but it cannot be made about the valid statistical difference as a whole. The non-probability sampling technique for quality research AIM was not tested in this type of study. Instead, the hypothesis is about the wider population But some understanding also under research the population is improved in the first case.
