    Abstract: <p>This study focuses on the usage of three phase sampling scheme in stratied random sampling for estimating the mean of the population under non‐response. Inspired by Chaudhary and Kumar, we have proposed a ratio‐type estimator of population mean utilizing the information on an auxiliary variable. The properties of the proposed family of estimators have been done. Empirical study has also been done in support of theoretical results.</p>
