Ma'am how did you find h?

@EnjoyMath 4 месяца назад

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...

@RahimaSirajRumu 4 месяца назад

Mam here you have odd number of rows so u can assume middle one but if i have only 6 row which one to assume as a=????

@EnjoyMath 4 месяца назад

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...

@rachitmishra99 День назад

you should divide xi-a by 4 not by 5 to find ui

@EnjoyMath 22 часа назад

@@rachitmishra99 Here the class size h is 5 ,not 4,because these are inclusive class intervals...so we need to include lower limit and upper limit value too, 101,102,103,104,105....5 of them ,so h is 5.. pls let me know if you have any questions....

@RahimaSirajRumu 4 месяца назад

Isnt the formula a+summation of fiui/n??

@EnjoyMath 4 месяца назад

For step deviation the formula is Mean = a+(Sigma fiui/n)*h Pls let me know if you have any questions..

@dakshinsharma9564 Месяц назад

101-105 me to "h" ka value to 4 na hoga

@EnjoyMath Месяц назад

Yeh inclusive class interval hai,isliye dono lower limit aur upper limit values ko bhi include karna hai, 'h' ka value calculate karne ke liye....isliye 101,102,103,104,105....5 observations hain...isliye h = 5... Pls let me know if you have any questions...

@Mrshort942 7 месяцев назад

I don't understand 121-125=4 why add 1

@EnjoyMath 7 месяцев назад

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....

@mohdjunaid5279 Месяц назад

Mam how did you find h?

@EnjoyMath Месяц назад

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 Pls let me know if you have any questions...
