Q. 104.0( 8 Votes )
In a frequency distribution table with 12 classes, the class - width is 2.5 and the lowest class boundary is 8.1, then what is the upper class boundary of the highest class?
Answer :
Given: number of classes = 12,
Class width = 2.5, and
Lowest class boundary = 8.1
Upper class is given by,
Upper class boundary = Lower class boundary + (width × number of classes)
Substituting values,
⇒ Upper class boundary = 8.1 + (2.5 × 12)
⇒ Upper class boundary = 8.1 + 30 = 38.1
Hence, upper class boundary is 38.1
