The branch of statistics that best describes the above fact is sample survey. In sample survey, we often deal with the collection, organization and analysis of data to make inference. Sample survey makes it easier to study effects of various variables on the suhject matter of interest and making inferences based on the data which have been obt'1ined under th e study. In this paper, data have been collected on the academic performance of students of /\e!clis I<:etema Senior Secondary School on the basis of grades scoreci in the Eth iopian School Leaving Certificate Examination (ESLCE) by both the regular and extension (even ing) program students. This could be done by simple random sampling and stratified random sampling. In the analysis of the data, we will be dealing with estimation, cnmr"risons ane! h ~/ pothe s i s testing of different parameters. Main and r;n rn h;nod ef fect!:' of various variables such as effects of field of study and sex 01' !ll" rPlf ormance of students will also be analyzed.
