Abstract
In survey sampling, systematic random sampling is commonly employed by researchers to draw a random sample from a population under study. Assuming the population size being finite, an efficient modified variant of the systematic random sampling is proposed for dealing with linear trend data sets. The findings of the study indicate that the suggested sampling procedure attains much more improvement in efficiency over some of the available popular sampling designs in those circumstances where the units of a finite population show an increasing or decreasing type of a linear trend. Besides numerical illustration, the mathematical expressions for efficiency have also been obtained.
