is the class interval of frequency distribution are 1-10,11-20,21-30,.....,51-60 then the size of even class is
Answers
Size of even class is
0.5 – 10.5, 10.5 – 20.5, 20.5 – 30.5, 30.5 – 40.5, 40.5 – 50.5, 50.5 – 60.5
Step-by-step explanation:
Given class interval of frequency distribution:
1 – 10, 11 – 20, 21 – 30, 31 – 40, 41 – 50, 51 – 60
(Lower limit of next class – Upper limit of previous class) ÷ 2
(11 – 10) ÷ 2
1 ÷ 2 = 0.5
(Lower limit of next class – Upper limit of previous class) ÷ 2 = 0.5
Now, subtract 0.5 from every lower limit and 0.5 from every upper limit
1 – 10 : 0.5 – 10.5
11 – 20 : 10.5 – 20.5
21 – 30 : 20.5 – 30.5
31 – 40 : 30.5 – 40.5
41 – 50 : 40.5 – 50.5
51 – 60 : 50.5 – 60.5
Therefore the size of even class is
0.5 – 10.5, 10.5 – 20.5, 20.5 – 30.5, 30.5 – 40.5, 40.5 – 50.5, 50.5 – 60.5
