Okubala kwa statistics

Enkola entono eza statistics

Ebyokuddamu ku data ya x

Ebyokuddamu ku data ya y

Ebyokuddamu bya regression

Okuyingiza data

Data: 95, 80, 80, 75, 75, 75, 50

Avereji ne standard deviation

Okukozesa ebyokuddamu mu fomula: ALPHA

Regression ya layini: yingiza emigogo gya x, y

Layini ya regression y = a + bx

Ebiteeberezebwa okuva ku layini

Regression ya quadratic: yingiza emigogo gya x, y

Layini empeteevu y = a + bx + cx²

Ebiteeberezebwa okuva ku layini empeteevu

Okuyingiza data n'okugirongoosa

Essuula 14: okukebera n'okulongoosa data. Obusaale obwa waggulu ne wansi buyita mu data gye wayingiza. Okukyusa ekimu, wandiika omuwendo omutuufu onyige DATA; second F C D esangula data eragiddwa.
