Question

Find the median for 1,4,8,13?

Answer 1

Given :- Find the median for 1,4,8,13?

Solution :-

we know that, after arranging the data in ascending order ,

when n = even number , median is,

• (n/2)th term + (n/2) + 1 th term / 2

so,

→ Median of 1,4,8,13 = 4 values = even number .

then,

→ n = 4

→ (n/2) th term = 4/2 = 2nd term = 4

→ (n/2 + 1)th term = 3rd term = 8

therefore,

→ Median = (4 + 8)/2 = 12/2 = 6 (Ans.)

SOLUTION

TO DETERMINE

The median for 1,4,8,13

CONCEPT TO BE IMPLEMENTED

Median :

Median is the middle most value of a set of observations when the samples are arranged in order of magnitudes ( Either in ascending or in descending)

EVALUATION

Here the given set of observations

1 , 4 , 8 , 13

The given set of data are in ascending order

Total number of observations = 4

Which is even

Now we know that Median is the middle most value of a set of observations when the samples are arranged in order of magnitudes ( Either in ascending or in descending)

Hence the required median

= Mean of 2nd and 3rd observations

= (4+8) /2

= 12/2

= 6
