Explanation :
N=390∴
N=390∴ 2
N=390∴ 2N
N=390∴ 2N
N=390∴ 2N =
N=390∴ 2N = 2
N=390∴ 2N = 2390
N=390∴ 2N = 2390
N=390∴ 2N = 2390 =195
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now,
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F ×h
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F ×h⇒Median=150+
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F ×h⇒Median=150+ 116
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F ×h⇒Median=150+ 116195−151
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F ×h⇒Median=150+ 116195−151
N=390∴ 2N = 2390 =195The cumulative frequency just greater than N/2 i.e.195 is 267 and the corresponding class is 150−160. So, 150−160 is the median class.∴l=150,f=116,h=10,F=151Now, Median =l+ f2N −F ×h⇒Median=150+ 116195−151 ×10=153.80
