kon sa formula use kia
To find the median of a frequency distribution we use the following formula:
X= l + h/f(n/2-c)
l =lower class boundary of the median class="71".95.
h=class interval size of the median class="3"
f =frequency of the median class="17"
n=total no. of observations=36
c =cumulative frequency of the class preceding the median class="10"
putting all these values in the formula:
X=l + h/f(n/2-c)
x= 74.067 Ans
yeh answer theek hai ?
muje yeh btaen google se kese math k qu
X= l+h /f (n/2-c)
X= 71.95+ 0.176(8)
Salam Tariq bhai ye steps kaisay solve kiyin hain?
~X = 71.95 + 0.17(8)
~X = 71.95 + 1.36
~X = 73.31
bhai jan 36 kaise aata hai . 8 x 3 = 24 ...!!
kya hm is trhn solve kar skty hain ya equation bna k hi solve karna hai
Steps aur solution lekhain bus. Table banane ki zaroorat nhi
