i) Monthly income of 7 households(in ascending order) = 1000, 1000, 1200, 1400, 1500, 1600, 10000
n = 7
median = (n + 1) / 2
= (7 + 1) / 2
= 8 / 2
= 4th term
= 1400
ii) Monthly income of 8 households(in ascending order) = 1000, 1000, 1200, 1400, 1500, 1500, 1600, 10000
n = 8
median = (n + 1) / 2
= (8 + 1) / 2
= 9 / 2
= 4th term and 5th term
= 1400+1500 / 2
= 2900 / 2
= 1450
