Whats the median and mode of 4,7,8,2,1,2,4,2,5,6,2​

Answer4.2

Step-by-step explanation:

Write the observations in ascending order.

1, 2, 2, 2, 2, 4, 4, 5, 6, 7, 8

Total number of observations = 11

Mean = Sum of observations ÷ Total number of observations

Mean = (1 + 2 + 2 + 2 + 2 + 4 + 4 + 5 + 6 + 7 + 8) ÷ 11

Mean = 43 ÷ 11 = 3.90

Median = ((n + 1) ÷ 2)th term [Here n is the number of observations]

Median = ((11 + 1) ÷ 2)th term

Median = (12 ÷ 2)th term

Median = 6th term

The sixth observation is 4.

Median = 4

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
