영문교정전문업체의 영문교정 엿보기

영문교정전문업체들은 어떻게 교정하는 지 살짝 엿보았습니다.The sampling method I used onin this study was fairunbiased, [Note: See Editor’s Note #1.] but there are a few aspects of things I would improve the way of sampling that could be improved. First of all, I used the systematic sampling method was used to sample from only one particular type of a share, “Iinvestment Ttrusts.  It This caused a data bias, because I actually choseonly companies fromoffering this one type of share were chosen. At the  beginningoutset, , I said it was stated that I the purpose of this investigatedinvestigation was to determine [Note: Please check the change.] whether a high-priced of shares makes more profits than a low-priced of ones.  IThis implied meant that the shares studied would is not only be “Iinvestment Ttrust s” shares but also other types of shares. However I investigated, only “Iinvestment Ttrusts” shares wereas a sampled.  This iswas a critical error. To

solve this problem, I could use

the Sstratified Ssampling method could be used to collect sample data.  However, in this case, it would be necessaryI have to know the total number of all companies onlisted in the newspaper just by simply counting from the top to the bottom of the list (there would be more than 1,000 companies).  If I could do this could be done, the Sstratified Ssampling method would provide me with a much fairerbetter opportunity of gettingobtaining a sample of data from all different types of a shares than the sSystematic sSampling method did.  Secondly, I could choose more than 54 sets of data could be taken as a sample. The more the sets of data were used, the more accurate would be the obtained results I could get.
