PRACTICAL RESEARCH Flashcards
is a word that refers to your method/process of selecting respondents
or people to answer questions meant to yield (produce/provide) data for a research study.
Sampling
- is the entirety of the group including all the members that forms a set
of data. Ex.(City, School, Barangay
Population
contains a few members of the population. They were taken
to represent the characteristics or traits of the whole population.
Sample
- crops up if the selection does not take place in the way it is planned.
Sampling errors
defined as the number of observations used for determining the estimations of a given population.
Sample Size
a list of the items or people forming a population from which a sample is taken
Sampling Frame
EVERY MEMBER OF THE POPULATION HAS THE
CHANCE OF BEING SELECTED. IT INVOLVES PRINCIPLE OR RANDOMIZATION OR CHANCE.
PROBABILITY SAMPLING or UNBIASED SAMPLING
This method involves randomly selecting a sample from the population
without any bias. It’s the most basic and straightforward form of probability sampling.
Simple random Sampling-
This method involves selecting every nth member of the population after a
random starting point is chosen
Systematic sampling
This method involves dividing the population into subgroups or strata and selecting a random sample from each stratum.
This technique is useful when the population is
heterogeneous(mixed) and you want to ensure that the sample is representative of different
subgroups.
Stratified Sampling
This method involves dividing the population into groups or clusters and then randomly selecting some of those clusters.
This technique is useful when the population is
spread out over a large geographical area. But It is not possible or practical to survey everyone
Cluster Sampling
- Not every member of the population has the equal chance of being
selected. It can rely on subjective judgement of the researcher.
Non – probability Sampling
You resort to this kind of sampling when you think you know the characteristics of the target population
Quota Sampling
Since the subject you expect to participate in the sample selection are the ones volunteering to constitute the sample, there is no need for you to do any selection process.
Voluntary sampling
You choose people whom you are sure could correspond to the objectives of your
study, like selecting those with rich experience or interest in your study.
are chosen based on the goals of the study. They may be chosen based on their knowledge of the study being conducted or if they satisfy the traits or conditions set by the researcher
Purposive Sampling
