Nikumbusheni CODING METHOD for finding MEAN and STANDARD DEVIATION in Mathematics

[Kibishi]

variance:c^2 ((Efu^2)/N +(Efu)^2/N) where c=class size, f= frequency u=d/c standard deviation: c((Efu^2)/N+(Efu)^2/N)^0.5

Saluti nyingi baba,itakatikiamo.Nimekuelewa vizuri.
Unaamanisha
Variance=C^2[sum of f(u^2)+sum of (fu)^2]/N.
S.D=C[[sum of f(u^2)+sum of (fu)^2]/N]^0.5
Halafu,kwenye hizo formula za variance na S.D,hiyo operation ya kujumlisha siyo kutoa hapo?,japo ni kitambo sana!
Saluti nyingi

kumbe njia unaiju, sasa ulikuwa unauliza nn km sio umbea!

Njia ninayoijua ni aliyoiandika ambayo siyo ya coding.
Ahsante sana.

 

[Kibishi]

Standard deviation just square root the variance

Upo sahihi baba kwenye hiyo theory.

 

[Kibishi]

mean=A+C.fu/f.where C= clas size. and u=d/c and d=X-A

Uko sahihi kabisa Ndugu mathx,umejichanganya kidogo tu,kwenye /f baadala ya /N.

 

[Syzygus]

Hesabu ni janga la Taifa, huu uzi utakuwa very unpopular maana wengi mtatuacha humu.

Maths huwa na-google tu,ukiona nimekuja huku kwa GREAT THINKERS ujue google mawenge.

 

[Kibishi]

Hamuwezi hata kujisomea kweli? Unashindwa kufanya hw unaleta humu? Jf watakuwepo kwenye mtihani wako?

Sina mtihani wowote,MATHS kwangu ni HOBBY.

ndio kashakosea hivyo.

We' mbona unashoboka sana?,huku hapakuhusu,comments zako hazihitajiki huku.
Sioni cha maana ulichochangia.

Wengi wanakosea bila kujijua,mbaya zaidi ktk mtihani.
Kinachosababisha wakosee ni:
-Wanaandika makosa wanachokifikiria
-Wanaandika makosa wanachokiongea/wanachokitamka.
-Wanaandika makosa namba waliyoishika/iliyobaki.

asante xna kaka

Ni kweli alama ya hapo ni kutoa badala ya kujumlisha, pamoja kaka

Daaah!!! Aisee mmu kuna rahaaa!! Ngoja niwahi kule maana hapa sipati kitu

samahani dada nimekosea!

samahani dada nimekosea!

Siyo bure unawashwa wewe.
