Quartile Interquartile range, semi-quartile range, outliers and data analysis from the box-and-whisker plots.
Logic and Formula have been applied and explained to Find Group Data Median.
Initial solution by Logic then by Formula to calculate Median after 8 min. This gives more accurate result than just Logic.
Thanks

Really great explaination
Big appreciation
We need teachers more like you

[ALIFOUAD]

Thanks man. It toke me a while but I eventually understood it

[ABGE]

Thank you sir.... I have my Business statistics exam tomorrow onwards.. It'll help me a lot rather my class teaching method!!

[yashica]

Sir please tell why you divide by 30 and multiply 10.
Sir please explain

[ushapaikaray]

Sir I don't understand your logic please explain better way

[kushagrajasaiwal]

sir how did you get to know from commulative frequency that 50th will lie in that 63 or it may lie in 90
here if i am correct, cf is the addition of previous no. of students not the position of them

Thank you .. I have Question .. how can I draw cumulative graph ?

[johnmwando]

My question is, how can u find the Median of grouped data without drawing the graph?

[ayeshadafedar]

When should we use the formula n/2 for even numbers?

[kritechnical]

Sir it is wrong to use calculator.😠😠😈😈
But explaintion is very nice😃😃😃😃😃😃
