Nrhiav Txoj Kev Zoo Tshaj Plaws (RegressionAnalysis)

  1. Nias tus yuam sij STAT dua.
  2. Siv cov TSI - 84 Ntxiv rau txoj cai xub rau selectCALC.
  3. Siv cov TSI - 84 Ntxiv rau nqes rau xaiv 4: LinReg(ax+b) thiab nias ENTER rau ntawm TSI - 84 Ntxiv rau, thiab lub tshuab xam zauv tshaj tawm tias koj nyob ntawd thiab ntawm Xlist: L1.

Tsis tas li ntawd, koj yuav ua li cas kos kab ntawm qhov zoo tshaj plaws ntawm lub tshuab xam zauv graphing?

  1. Kauj ruam 1: Sau cov ntaub ntawv hauv koj lub laij lej. Nias …, ces nias 1: Kho kom raug …
  2. Kauj Ruam 2: Nrhiav cov kab zauv Regression Equation. Nias …, ces ~, thiaj li yuav highlight CALC, ces xaiv 4: LinReg(ax+b). Koj yuav tsum pom qhov screen.
  3. Kauj Ruam 3: Qhia koj cov ntaub ntawv thiab cov kab uas haum zoo tshaj plaws. Ua ntej, kos cov ntaub ntawv. Nias y o (STAT PLOT).

Ib yam li ntawd, koj ua li cas cov kab regression ntawm TI 84? Nias [STAT] nkag mus rau cov ntawv qhia zaub mov. Nias tus yuam sij xub xub kom ncav cuag CALC ntawv qhia zaub mov thiab tom qab ntawd nias 4:LinReg(ax+b). Xyuas kom Xlist tau teeb tsa ntawm L1, Ylist tau teeb tsa ntawm L2 thiabStore RegEQ tau teeb tsa ntawm Y1 los ntawm nias [VARS] [→] 1:Function thiab1:Y1.

Ib yam li ntawd, koj tuaj yeem nug, koj yuav ua li cas ua ib kab ntawm qhov zoo tshaj plaws ntawm TI 83?

  1. Nrhiav txoj kab uas zoo tshaj plaws siv TI-83+
  2. (Clear tag nrho cov haujlwm uas tau khaws tseg yav dhau los)
  3. Nkag mus rau cov ntaub ntawv:
  4. STAT. 1: Khob.
  5. Yog tias muaj qhov tseem ceeb twb khaws cia hauv L1 thiab L2, taw qhia L1, nias Clear, ces Enter. Ua tib yam nrog L2.
  6. Txhawm rau tsim daim duab scatter:
  7. Txhawm rau xam cov kab uas haum zoo tshaj plaws.
  8. Stat. Highlight CALC.

Txoj kab ntawm qhov zoo tshaj plaws yog dab tsi?

Kab ntawm Qhov Zoo Tshaj Plaws . A kab ntawm qhov zoo tshaj plaws haum (los yog "trend" kab ) yog ncaj kab uas zoo tshaj plaws sawv cev cov ntaub ntawv nyob rau hauv ib tug scatter zajlus. Qhov no kab tuaj yeem hla qee cov ntsiab lus, tsis muaj cov ntsiab lus, lossis tag nrho cov ntsiab lus. Koj tuaj yeem tshuaj xyuas kab ntawm qhov zoo tshaj plaws haum nrog: 1.
