Find the median of 17, 23, 36, 12, 18, 23, 40 and 20
उत्तर
Arranging in ascending order, we get
12, 17, 18, 20, 23, 23, 36, 40
Here, number of terms = 8 which is even
∴ Median = `1/2 {"n"/2 "th term"+("n"/2 + 1)"th"}`
`= 1/2 {8/2"th term" + (8/2 + 1)"th term"}`
`= 1/2 {4 "th term" + 5 "th term"}`
`= 1/2 {20 +23}`
`= 1/2 xx 43 = 21.5`
