Means choosing from a large population the respondents or subject to answer your research questions. The ENTIRE population is INVOLVED but for your research study, you CHOOSE ONLY PART OF THE WHOLE

Sampling

FACTORS affecting sample selection

1. Sample size 2. Sampling Technique 3. Heterogeneity of population 4. Statistical Techniques 5. Time and Cost

How be should the sample be?

Sample size

Probability sampling and non probability sampling

Sampling techniques

Compose of individuals with varied abilities

Heterogeneity of population

How precious or accurate your methods

statistical techniques

Making the sampling frame

Time and Cost

This is sampling methods that makes you base your selection of repondents on pure chance.

Probability sampling

Different probability sampling techniques

1. Simple random sampling 2. Systematic sampling 3. Stratefied sampling 4. Cluster sampling

Choosing respondents based on pure chance

Simple random sampling

Picking our from the list every 5th or every 8th member listed in the sampling frame until the completion of the desired total number of respondents

Systematic sampling

Choosing a sample that will later on be subdivided into strata, sub groups or sub samples during the stage of the date analysis

Stratified sampling

Selecting respondents on cluster, rather than in seperate individuals such as choosing 3 classes of 40 students each from a whole population of 5,000 students

cluster sampling

Sampling methods

1. Probability sampling 2. Non probability sampling

The sampling techniques included in this category are NOT CHOSEN RANDOMLY but purposefully

Non Probability sampling

Different Non Probability sampling

1. Quota sampling 2. Voluntary sampling 3. Purposive sampling 4. Availability sampling 5. Snowball sampling

Choosing specific samples that you know correspond to the population in terms of one, two or more characteristics

Quota Sampling

Selecting people who are very much WILLING to participate as Respondents in the research project

Voluntary Sampling

Choosing respondents whom you have JUDGES as people with good background knowledge or with great enthusiasm about the research

Purposive sampling

Picking out people who are EASY TO FIND or located and willing to establish contact with you

Availability sampling

Selecting sampling from several alternative samples like drug dependant, human traffikers, street children and other wayward Not easily located People who are moving from place to place

Snowball sampling

The most prefered sampling technique in qualitative or quantitative research is

Random Sampling

Required the use of statistical method in measuring sample

random sampling

3 Probability sampling technique

1. simple random 2. stratified random 3. systematic random

ADVANTAGE: the most accurate theoretically and influence only by chance DISADVANTAGED: unavailable list if the entire population sometimes or oreventions of random sampling by practical consideration

Random sampling

ADVANTAGE: Assures large sample to Subdivide on important variables, needed when population is too large to list Can be combined with other techniques DISADVANTAGED: Can be BIASED if strata are given false weights, unless the weighting procedure is used for overall analysis

Stratified Sampling

ADVANTAGE: Similar to random sampling, often easier than random sampling DISADVANTAGED: Sometimes permit bias

Systematic Sampling

ADVANTAGE: Easy to collect data on the subject DISADVANTAGED: Prone to bus when the numerous is small

Cluster Sampling

ADVANTAGE: Available when random sampling is impossible quick to do DISADVANTAGED: presence of bias NOT CONTROLLED by the quota system
