Dab tsi yog coding hauv kev tshawb fawb zoo ? Coding yog tus txheej txheem ntawm daim ntawv lo thiab teeb tsa koj zoo cov ntaub ntawv los txheeb xyuas cov ntsiab lus sib txawv thiab kev sib raug zoo ntawm lawv. Thaum twg coding cov lus teb rau cov neeg siv khoom, koj muab cov ntawv sau rau cov lus lossis kab lus uas sawv cev tseem ceeb (thiab rov ua dua) cov ntsiab lus hauv txhua qhov lus teb.

Khaws qhov no hauv kev xav, dab tsi yog txheej txheem coding hauv kev tshawb fawb zoo?

Hauv kev tshawb fawb zoo , coding yog "koj txhais li cas cov ntaub ntawv koj tab tom txheeb xyuas txog" (Gibbs, 2007). Coding yog a txheej txheem ntawm kev txheeb xyuas ib nqe lus hauv cov ntawv nyeem lossis lwm yam khoom siv (daim duab, duab), tshawb nrhiav thiab txheeb xyuas cov ntsiab lus thiab nrhiav kev sib raug zoo ntawm lawv.

5 txoj kev sau cov ntaub ntawv yog dab tsi? Cov txheej txheem sau cov ntaub ntawv zoo

  • Open-Ended Surveys thiab Questionnaires. Qhov sib txawv ntawm qhov kaw-kawg yog qhib-kawg kev tshawb fawb thiab cov lus nug.
  • 1-on-1 Interviews. Kev xam phaj ib-rau-ib (los yog ntsej muag) yog ib hom kev sau cov ntaub ntawv hauv kev tshawb fawb zoo.
  • Focus pawg.
  • Kev soj ntsuam ncaj qha.

Ua li no, puas yog coding qualitative lossis quantitative?

Hauv social sciences, coding yog txheej txheem analytical uas cov ntaub ntawv, nyob rau hauv ob qho tib si kom muaj nuj nqis daim ntawv (xws li cov lus nug tshwm sim) los yog zoo daim ntawv (xws li kev xam phaj transcripts) yog categorized los pab kev soj ntsuam. Ib lub hom phiaj ntawm coding yog hloov cov ntaub ntawv mus rau hauv ib daim ntawv uas haum rau computer-pab tsom xam.

Ob hom code yog dab tsi?

Algebraic coding txoj kev xav yeej muab faib ua ob loj hom codes : Linear thaiv cov lej . Convolutional cov lej.

Linear codes

  • code lo lus length.
  • tag nrho cov lej ntawm cov lus siv tau.
  • qhov tsawg kawg nkaus nrug ntawm ob lo lus siv tau, siv feem ntau yog Hamming nrug, qee zaum kuj muaj lwm yam kev ncua xws li Lee nrug.
