Measures of dispersion; calculation of mean, median, mode of grouped and ungrouped data
Formula
\(\text{Median}=\text{value whose cumulative frequency first exceeds }\frac{N}{2}\)
Variables: \(N=\sum f_i\): total frequency.
Conditions: Values arranged in increasing order and cumulative frequencies computed.
Median from frequency table.
