Question

uncategorized data: 4,6,9,3,10,13,2 find the mean deviation from the mean​

Answer 1

Answer:

The mean of the data is 45.28571429

Answer 2

Answer:

3.28

Step-by-step explanation:

Arrange data in ascending order,

2,3,4,6,9,10,13

No. of observation n=7(odd)

Median = n+1/2 = 4th observation  

Hence median =6

Now we calculate mean deviation about median, i.e;

⟹   ∑∣xi − M∣/7 (where i is in subscript) =

​

 ∣2−6∣+∣3−6∣+∣4−6∣+∣6−6∣+∣9−6∣+∣10−6∣+∣13−6∣/7 = 23/7 = 3.28

I hope it helped :)
