INTRODUCTION
The formation of the sample
population is the first stage
of the research, which
precedes the data analysis.
In order to ensure the
reliability of the research
results, it is necessary to
choose the right sample
that would reflect the
general picture.
STATISTICAL APPROACH
TO SAMPLE FORMATION
The statistical approach to sampling is
based on the theory of probability and is
usually used to obtain a sample that will be
representative of the general population.
This approach involves the random selection
of elements from the general population,
which allows to ensure the objectivity of the
research and avoid distortions of the results.
AN APPLIED APPROACH TO
SAMPLE FORMATION
The applied approach to sample formation
is based on the selection of representatives
from a specific group according to
specified criteria
This approach allows you to get the
necessary amount of information for the
minimum time and effort
METHODS OF SAMPLE
FORMATION
There are various sampling techniques
such as proportional sampling, class
sampling and stratified sampling.
Each of these methods has its
advantages and disadvantages, so
the choice of method depends on
the specific conditions of the study.
80%
Estimating the sample size depends on many factors, such as the
confidence level, the error rate, and the size of the study group.
Different statistical methods can be used to estimate the sample
size, such as the Cochrane formula and the Taylor formula.
