From the following data , determine the mode by grouping method :
`{:("Size",7,8,9,10,11,12,13,14,15,16,17),("Frequency",2,3,6,12,20,24,25,7,5,3,1):}`

Given the following data , calculate mode using the grouping technique . {:("Size",2,3,4,5,6,7,8,9,10,11,12,13),("Frequency",3,8,10,12,16,14,10,8,17,5,4,1):}

Calculate mode from the following series : {:("Size",1,2,3,4,5,6,7,8,9,10,),("Frequency",8,6,10,12,20,12,5,3,2,4,):}

Calcilation Q_(1),Q_(3),D_(6)and P_(85) from the following data : {:("Size",10,11,12,13,14,15,16,17,18),("Frequency",3,4,5,12,10,7,5,2,1):}

Calculate the median from the following data : {:("Size",10,12,14,16,18,20,22),("Frequency",2,5,12,20,10,7,3):}

{:(8,7,10,12),(13,12,15,17),(10,9,?,14):}

Calculate Q_(1),Q_(3),D_(7)and P_(89) from the following data : {:("Size",1,2,3,4,5,6,7,8,9,10,11),("Frequency",5,8,15,22,36,44,28,17,12,9,3):}
