h or the class size is found by subtracting the lower limit value from upper limit value of any class interval...for example for a data 0-3,3-6,6-9,9-12........ Take any class interval say 3-6, subtract 3 from 6, we get 3 ....that's the class size or h value Pls let me know if you have any questions...
Yes,that scenario will arise if there are even number of rows....for example if there are 6 rows, and the xi values are say, 15,25,35,45,55,65 then you can either choose assumed mean as 35 or 45....your choice.... pls let me know if you have any questions...
When calculating mean, it is not compulsory to convert inclusive class intervals to exclusive...even if you convert you will get the same answer that you will get without converting..pls let me know if you have any questions....
@NikhilWagh-os2zl thank you so much for the appreciation!! 👍👍👍For mean calculation, it is not mandatory to convert to continuous class intervals... Because as you can check in the formula.. We only take the class mark... Which does not change whether we convert or not.... You can verify by solving above question by converting to continuous class intervals and find mean... It will be same.... Pls let me know if you have any questions...
Class mark is sum of lower limit and upper limit divided by 2....in this example it is not decimal...but it can be decimal....depends on the values of lower limit and upper limit... pls let me know if you have any questions....
h is equal to 5....These are inclusive class intervals....so both upper limits and lower limits are included in the class interval....so 101-105 class size will be 101,102,103,104,105....so h= 5..pls let me know if you have any questions...

Yes, there are 2 formulae....population data means we know all the actual data and actual mean value...then we can use denominator as n. However, if there is any real life data, it is impossible to get the complete picture, we can only take a sample,that is sample data...then we keep denominator as n-1..... .pls let me know if u have any questions
121-125 is not subtraction of 125 from 121...it denotes the class interval whose lower limit is 121 and upper limit is 125. So we usually write the class interval as 121-125. The 5 is obtained by subtracting 118 from 123 Pls let me know if you have any questions....

Mam how did you find h?
Here we have inclusive class intervals,so both lower limit value and upper limit value are included in each class interval,so h= upper limit value - lower limit value + 1.
For exclusive,
h= upper limit value - lower limit value,because upper limit value is excluded, but for inclusive,we add 1 because upper limit value is included
So here h= 105-101+1=5
