The median of 1, 2, 0, 3, 7, 5, 2.5 is ……………..?A) 1B) 2C)2.5

1.	The median of 1, 2, 0, 3, 7, 5, 2.5 is ……………..?A) 1B) 2C)2.5D) 3
Answer» Correct option is C) 2.5 Ascending order of given observations is 0, 1, 2, 2.5, 3, 5 and 7. Number of observations is n = 7 Median = \((\frac{n+1}2)^{th}\) or \((\frac{7+1}2)^{th}\) = 4^th term in ascending order of observations. \(\therefore\) Median = 2.5

The median of 1, 2, 0, 3, 7, 5, 2.5 is ……………..?A) 1B) 2C)2.5D) 3

Answer»

Correct option is C) 2.5

Ascending order of given observations is 0, 1, 2, 2.5, 3, 5 and 7.

Number of observations is n = 7

Median = \((\frac{n+1}2)^{th}\) or \((\frac{7+1}2)^{th}\)

= 4^th term in ascending order of observations.

\(\therefore\) Median = 2.5
