Draw Samples with the Desired Properties from a Data Set
A tool to sample data with the desired properties.Samples can be
drawn by purposive sampling with determining distributional
conditions, such as deviation from normality (skewness and kurtosis),
and sample size in quantitative research studies.
For purposive sampling, a researcher has something in mind and participants that
fit the purpose of the study are included (Etikan,Musa, & Alkassim, 2015)
<doi:10.11648/j.ajtas.20160501.11>.Purposive sampling can be useful for answering
