Find the Correct Answer from the Alternatives Given. the Formula to Find Mean from a Grouped Frequency Table is X = a + ∑ F I U I ∑ F I × H G . - Algebra

Question

Find the correct answer from the alternatives given.

The formula to find mean from a grouped frequency table is  \[X = A + \frac{\sum f_i u_i}{\sum f_i} \times hg\] .

Options
  • \[\frac{x_i + A}{g}\] 

  • \[\left( x_i - A \right)\] 

  • \[\frac{x_i - A}{g}\]

  • \[\frac{A - x_i}{g}\]

Solution

To find mean of a grouped frequency table using 

\[X = A + \frac{\sum f_i u_i}{\sum f_i} \times hg\]
In this formula, \[u_i = \frac{x_i - A}{g}\] 
  Is there an error in this question or solution?
