yeap assignment ban jaye gi............ 

aur ban gai hai :) chk on page 3

secnd qstion k a part ma ap ko medin ka formula dekan ha 

median=X childa =l+h/f(n/2-C.F)

is ma 

l= the lower class boundary of the medain class(n/2)

h=the class intrval size of the median class

f = the class frequncy of tmedian class 

n=sigma f=total frequncy 

C.F=the cumulative frequenchy preceding the medin class cumulativ freq

c.b              f                     c.f

145-150        4                 4

150-155        6                  10

155-160       28                 38

160-165      58                    96

165-170     64                  160  

170-175    30                  190

toal           190

median class or the modal class = (n/2)th=190/2=95 th (to see in c.f)

so the medain r modal class is 160-165         58                    96

 by putng the valus in formula 

medain = 160 +5/58(95-38)

           =160+5/58(57)

            =164.9138

No it's wrong! mein ny upload key hain file page 3 pr chk karo.

2 b)

median=X childa =l+h/f(n/2-C.F)

is ma

l= the lower class boundary of the medain class(n/2)

h=the class intrval size of the median class

f = the class frequncy of tmedian class

n=sigma f=total frequncy

C.F=the cumulative frequenchy preceding the medin class cumulativ freq

c.b              f                     c.f

145-150        4                 4

150-155        6                  10

155-160       28                 38

160-165      58                    96

165-170     64                  160

170-175    30                  190

toal           190

 

median class or the modal class = (n/2)th=190/2=95 th (to see in c.f)

so the medain r modal class is 160-165         58                    96

by putng the valus in formula

medain = 160 +5/58(95-38)

=160+5/58(57)

=164.9138




Q2 part1 

median =164.9138

H.M.=164.862

P23=160.49

Q2 Partb

G.M.=21.66

match with yr answers and justify

Galat hai. CF k column mein 96+64 karna hai 160 banay ga aur nichy walaq 190.
