Question

xi =1 2 3 4 5 6 7 median​

Answer 1

$x = \frac{1 + 2 + 3 + 4 + 5 + 6 + 7}{7} \\ x = \frac{28}{7} = 4$

4 is the mean of the numbers.

Answer 2

Answer:

Median

Step-by-step explanation:

Observations already given in ascending order

1, 2, 3, 4, 5, ,6 ,7

n = 7

So Median = n+1 / 2 th  observation

                  = 7+1/2 = 8/2 = 4th observation

      Median = 4
