Please help find the MAD

 0.5

Step-by-step explanation:

1. I calculate the mean= sum of  the data/number  of data=

(3+5+4+4 )/4=16/4=4

2. I calculate distance between the data and the mean

|3-4|=|-1|=1

|4-5|=|-1|=1

|4-4|=0

|4-4|=0

3. Add the distances

1+1+0+0=2

4. Divide the sum by the number of data points

2/4=0.5

0.5

3 + 5 + 4 + 4 = 16 ÷ 4 = 4

4 - 3 = 1

4 - 5 = 1

4 - 4 = 0

4 - 4 = 0

1 + 1 + 0 + 0 = 2 ÷ 4 = 0.5
