Sampling procedure

Sampling procedureA researcher will have to make decisions in selecting the participants of the study who will provide the needed data to answer the research question posted and the objectives of the study. In this chapter, sampling techniques and procedure will help in guiding the researcher to choose the subjects or respondents of the study.Research requires an effective and effective means of ensuring the quality of data that will be gathered. This means selection of appropriate subjects or respondents of the study that will generate data specific to the purpose or objective of the inquiry. Guidepost on the Sampling Procedure Universe is a totality of elements to which research findings may apply. This also refers to the target population, the group of people or objects from which the researcher intends to collect data and generalized the findings of the study.Elements refers to entities that make up the sample and the population. Example Patients; student nurses, staff nurses Population- refers to the accessible group of individuals from which the sample will ne drawn by the researcher, consistent with specific criteria, or the total possible participation of the group in the study. This also refers to that portion of the universe accessible to the researcher.Specific population types:Target population. This is the group of the individuals or objects which of interest to the reseacher and about which speculative information is desired.Example: All students nurses of X College of NursingAll patients in medical surgical wardSubjects or respondents population. This is the group of individuals or objects chosen to provide actual data and information needed in a reseach.Example: BSN IV or the graduating student nurses of X College of Nursing Stratum- this term describes a mutually exclusive segment of the population, distinguished by one or more traits or qualification.Example: Age- youngest to oldestCivil status- single or married

Eligibility or Inclusion criteria. This is the criteria or characteristics specified in the population to included in the study. Exclusion criteria are the characteristics of the population that are not specified in the study and are therefore disqualified to participate in the study

SamplingIs the process of selecting representative portions of the population to represent the entire population, This a practical and efficient means of ensuring the quality of data that will be gathered.Sampling unitSample frameSample Design.Sampling Size - This is the total of samples who will participate in the study after the sampling design was completed.

Sample is a portion of the population from which data will be solicited for purposes of the researcher. It is a subgroup of the population which constitutes the subjects or respondents of the study.Sample may be categorized as follows: respondents or participantsSubjectsKey informants or volunteer samplesIdentify the target Population or the Universe This refers to the group to which the researcher wishes to apply ones findings.Examples: All graduating Students All students nurses of X hospital.-All juvenile diabetic of metro Manila

Identify the Respondent Population. It is vital for the researcher to determine the specific portion of the available target population from whom one will fraw needed data and information. Examples: BSN graduating students; Staff nurses in the ICU; juvenile diabetic with insulin deficiency

Specify the Inclusion and Exclusion Criteria for the Respondent selection. The criteria must be specific to the characteristics of the respondents. The researcher should state clearly the characteristics of the population required in the study using the inclusion or Eligibility criteria and the characteristics that the respondents or subject must not possess or the exclusion in selecting the respondents of the study Examples: Inclusion Criteria: BSN graduating students with no RLE deficiencies, male and demale Specify the sampling Design. Once the respondents population is identified, the researcher must then decide how the samples will be chosen and how large this will be by considering the representative proportion of the population: Examples: Probability sampling, suing simple random or the use of non probability sampling using purposive sample Recruit the subject. When the sampling design has been determined, the next step is to recruit the subjects and seek their cooperation and support bibliographyA research guide in nursing education : building an evidence-based Practice
