Modal class = 20-30 (( f_1 = 15 )) ( L = 20, f_0 = 9, f_2 = 8, h = 10 ) Mode = ( 20 + \frac15 - 92\times15 - 9 - 8 \times 10 = 20 + \frac613 \times 10 ) = ( 20 + 4.615 = 24.615 )
These methods use quantities as weights. The most common ones mentioned in Sandeep Garg Solutions for Class 11 are: Uses base year quantities ( Q0cap Q sub 0 ) as weights. Formula: Paasche’s Method: Uses current year quantities ( Q1cap Q sub 1 ) as weights. Formula: Modal class = 20-30 (( f_1 = 15
Index Numbers are specialized averages designed to measure the relative change in a group of related variables. Key topics include: Formula: Index Numbers are specialized averages designed to
