If we take number of class intervals according to the the given data, then in which circumstances the formula "RANGE/CLASS SIZE" is used?
If we go by formula, then we will have to use 10 class intervals whereas going by suggestion of Mr. Manmit Singh, we will have to use 11.
My following question has not been answered yet. Please answer.
In which circumstances are we required to calculate NUMBER OF CLASSES by dividing "RANGE" by "CLASS SIZE"?
Is it correct to calculate NUMBER OF CLASSES (which is 10 as per my calculation) in the following example?
Construct a frequency table with class intervals 0-5 (5 not included) of the following marks obtained by a group of 30 students in an examination.
0, 5, 7, 10, 12, 15, 20, 22, 25, 27, 8, 11, 17, 3, 6, 9, 17, 19, 21, 29, 31, 35, 37, 40, 42, 45, 49, 4, 50, 16
0 – 5
5 – 10
10 – 15
15 – 20
20 – 25
25 – 30
30 – 35
35 – 40
40 – 45
45 - 50
If second observation 5 was included in class "5-10" then why 29th observation that is 50 was included in class '45-50"?
Do we need to create one more class for 50? In that case number of classes will be 11. Whereas range divided by class size =number of classes that is 10.
Yes, you are correct. The 29th observation i.e., 50 should not be included in the interval 45-50. The observation 50 should be included in the interval 50-55.
So, make another class interval 50-55 which has one tally mark entry and frequency as 1.
The class interval 45-50 would have two tally mark entries and frequency as 2.
Yes, it would be correct to make another class interval 50-55.
We take the number of class intervals according to the given data.
In this case, the values range from 0 to 50.
So, we have 11 class intervals (11thbeing to include the observation 50)
Hope this clears your doubt.
