Nikumbusheni CODING METHOD for finding MEAN and STANDARD DEVIATION in Mathematics

[Kibishi]

Kama kichwa cha habari kinavyoonyesha.
Nisaidieni ile formula inayoitwa CODING METHOD iliyopo katika topic ya STATISTICS inayotumika kutafuta MEAN,STANDARD DEVIATION na VARIANCE
Natanguliza shukrani.

Si' kuna walimu na wanahisabati humu?,mbona kimya?

 

[Eng Kimox Kimokole]

Mean=summation of frequency/N

 

[Eng Kimox Kimokole]

Variance, take each different of the frq from the mean (normally the centre) then square it and plus those differents, the answer you get devide by N (total number of frq)

 

[Eng Kimox Kimokole]

Standard deviation just square root the variance

 

[Mgumu04]

mean=A+fd/N

where by:
A=Assume/coding mean
f=frequency
d=x-A(deviation)
N=total frequencies

 

[itakiamo]

MEAN: A+(CEFU)/N Where A=assumed mean C=class size E=summatio(sigma notation F=frequency N=Total frequencies/numbers U= (d/c) where d=deviation and c=class size

 

[itakiamo]

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

mbona ya fani yangu huwa hamuulizi au mnayajua sana??

 

[kibai]

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

Ya kaisari, tunakuachia wewe mwenyewe kaisari

 

[mathx]

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

Kujisomea tumeshajisomea sana.Tunakumbuka vitu vingi,tumesahau vitu vichache,vichache hivi visipoonekana google,au google kukiwa na mawenge wataalam JFwapo wa kuwauliza.
Kuhusu kwenda LIBRARY tumeshaenda sana,na ndiyo inayotufanya tukumbuke vitu vingi.
Kumbuka ya kwamba google ni library mojawapo.

Mean=summation of frequency/N

Kimox Kimokole,hiyo ni njia ya kawaida,na siyo ya Coding.

www.ask.com hapo utapata majbu[/Q...page of results found haikuwepo,sikuifikiria.

 

[Kibishi]

Variance, take each different of the frq from the mean (normally the centre) then square it and plus those differents, the answer you get devide by N (total number of frq)

Hiyo ni njia ya O-level ya kawaida,na wala siyo coding method.

 

[Kibishi]

mean=A+fd/N

where by:
A=Assume/coding mean
f=frequency
d=x-A(deviation)
N=total frequencies

Hiyo njia siyo coding,ni ya kawaida tu ya assumed mean method.

 

[Kibishi]

MEAN: A+(CEFU)/N Where A=assumed mean C=class size E=summatio(sigma notation F=frequency N=Total frequencies/numbers U= (d/c) where d=deviation and c=class size

Shukrani sana Ndugu itakatikiamo,iko hivyo hivyo.Sasa nimekusoma.Unamaanisha
Mean=A+C(sum of fU)/N.

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