3.2 Methodof theAnalysis

Inwriting this thesis,Thewriteruses amethodofresearch,namely: descriptivequalitative.Incollecting data,Thewriterusesdescriptivequalitative methodbygiving thestudents awritten testin themultiple-choiceformand completion teston simplepasttense. Djajasudarma1993:8statesthatdescriptivequalitativemethod isa method thatisusedtodescribethedatasystematicallyandaccurately.Thisresearchdoesnot stoponly incollectingandexaminingthedata,butalsoanalyzingitinordertogeta conclusionaboutthe tenthyearstudents’abilityofSMAN21Medaninusingsimple past tense.

3.3 Populationand Sample

Gay 1987:102says,“Populationisthegoupofinteresttotheresearcher,the grouptowhichsheorhewouldliketheresultofthestudytobegeneralized.”It means that population is total object or numbers that should be studied in the research. 26 The population of this research is the 20142015 tenth year students of SMAN21Medan.Therearesevenclassesaltogetherandeachclassconsistof40 students.So,there are280studentsofthe tenthyear.Realizing that thenumbersare greatenoughandThewriterwillfacesomedifficulties,especially theenergy,time, andfund,so Thewritersets 25of themfromeach class tobecometherespondents so that theconclusion ofthattest isaccurate. Arikunto 1993:109 says. “A sampleis a limited number of elements selectedfromapopulationtoberepresentativeofthatpopulation”.Itmeans thatnot all thepopulation toberespondents.So, thewholeoftherespondentsin thisresearch are70students.Itis25.ThereasonfortakingthisnumberbasedonArikunto’s idea1993:120saysthatifthepopulationconsistsofalargenumbermorethan 100,thesamplecanbetakenfrom10-15or20- 25ormore,itdependson theabilityoftheresearcherbyconsideringtheirenergy,time,andfunds.Itmeans that thepercentageof thesample is70 x 100 =25 280 Basedonthequotation above,thesampleusedtorepresent thepopulation in thisresearchisadequate.They arenotclassifiedonthebasisoftheirgradeof intelligence.Therefore,allofthemhavethesameopportunity tobeselectedasthe sample. Inobtaining thesample,Thewriter usesrandomsampling technique consideringwhatGay1987:104saysthatrandomsamplingisthebestsinglewayto obtain arepresentativesample.
