Question

wages=20_30,30_40,40_50, 50_60,60_70 FREQUENCY=25,12,15,13,5 FIND MEDIAN wage ​

Answer 1

Explanation:

40+50/2=90/2=45

median is 45

Answer 2

Answer:

25+12+15+13+5=70÷2=35

=30+(70÷2-25)×10÷12

=30+10×10÷12

=30+8.34

=38.34

Explanation:

In continuation frequency distribution median find as follow

fist find class by using formula N/2

Now find median by using formula:

L+(N/2_CFp)×D/F

where as L=lower limite of that class

N=total of Frequency .

CFp= cumulative Frequency pervious

D= Class difference

F= Frequency of that class
