median :
​

Answer 1

Answer:

Mean Deviation about Median = 1

Step-by-step explanation:

data 1, 4, 3, 2, 4, 5. 4

Data is ascending order

1  ,  2   ,  3   ,  4  ,   4   ,  4 ,  5

7 observation

so median = 4th Observation

Median = 4

Mean Deviation about Median =   ( |1-4|  + | 2-4| + |3-4| + |4-4| + |4-4| + |4-4| + |5-4| ) /7

= ( 3 + 2 + 1 + 0 + 0 + 0 + 1) /7

= 7/7

= 1

Mean Deviation about Median = 1
