Modi (Takwimu)

Katika takwimu, modi ya sampuli ya data ni thamani x ambayo inatokea mara nyingi zaidi.

Modi, kati na wastani.

Kwa mfano, katika sampuli ya data hii 1,3,3,5,7,8,9;15,18,3,30 modi ni "3" kwa hyvio namba "3" inatokea mara nne.

Kama wastani na kati, modi ni kipimo cha mwelekeo wa kati.

Kwa programu ya takwimu R

Ili mtafute modi kwa lugha ya programu ya takwimu R mandike :

SampuliYangu<- c(7, 4, 3, 6, 9, 2, 9, 13, 9, 9)

library(modeest)

mlv(SampuliYangu, method = "mfv")

Mode (most likely value): 9

Bickel's modal skewness : -0.1

Call: mlv.default(x = SampuliYangu, method = "mfv")
