I am really so happy that the video helped in clearing your doubt...Thank you so much for the wonderful feedback. All the very best for your economics exam 👍👍👍👍
Thank you mam, wonderfully explained. So we can conclude that if the classes are inclusive in the question we will have to convert them into exclusive regardless whatever is asked in the question right?? Please reply
Thank you so much for the appreciation!! 👍👍👍 Yes, for most of the questions, we have to convert. However, for some questions it is not compulsory to convert to exclusive...for example- while finding mean of data, the class marks for exclusive and inclusive data is same,so it's not necessary to change....both ways we get the same answer. Pls let me know if you have any questions....
The best explanation tq so much 😘 mam understood very well n mam I have doubt there is a sum where it is given as Mark 0-10 10-20 20-30 Students 5 6 10 How do I solve this sum mam n this sum is exclusive series And is this related to this vdo
Thank you so much for the appreciation!! Happy to be of help 👍👍 Yes,this question is based on exclusive series,so you don't have to do any conversion,directly proceed...what is the question? Do we have to find mean median or mode?
From my point of view, inclusive class intervals have no importance, because as in given example we write first class from 0 to 5 and next class 6 to 11, hence 5.5 not lie in both these intervals. So I think inclusive class intervals are useless. So always we have to make exclusive class intervals. Am I right? Next question, why we study inclusive class intervals, I think we have to study only exclusive class intervals?
Really glad that you are interested in knowing more about the ' why' as much as about the 'how'....great going !!👍👍👍 We don't have to convert inclusive to exclusive class intervals for mean calculation. You may try a question which has inclusive class intervals and calculate mean first by converting to exclusive,and then without any conversion...you will get the same means value... For the second question, i have tried questions where we create class intervals and frequency distribution from raw data...it's always easier to create inclusive class intervals because we don't have to worry about excluding the upper limit value from that class interval. We can include both the class limits in that class interval...so I think in real world,data is collected in the form of inclusive class intervals also....but if any other viewer has any other information on this question,pls share in the comments,so that we all can learn... really liked your question !! 👍👍👍

Hello, yes I think there will be data which can be negative, for example temperatures, negative marks in some competitive exams, in physics velocity acceleration force can also be negative. In economics also I think growth rate can be negative. In such cases there will not be problem of different common difference. For example , if we have following class intervals -5 to 0 0 to 5 5 to 10 etc... The common difference ( class size ) for the first class interval will be 0- (-5) ( upper interval - lower interval ) which is 5. And for the other class intervals also we will get 5 as the difference. Hope your doubt is resolved...pls let me know...
@@EnjoyMathhello, thanks for replying. I have a question,If the continuous grouped data is given as 0-5 , 6-10 , 11-15 , 16-20 , 21-25 , then what will be the class size for this data?

Class width will change according to the question. It is the upper limit - lower limit. Suppose class intervals are 0-5,5-10,10-15,...... The class width = 5-0= 5 Pls let me know if you have any questions
