Answer:
10
Step-by-step explanation:
Step 1: Arrange the number is ascending order
The numbers are 5, 10, 15, 12 and 8
Ascending order = 5, 8, 10, 12, 15
Step 2: Assumed a mean:
Taking the centre number as the most likely one
Assumed Mean = 10
Step 3: Difference the difference of each number with the assumed mean:
5 - 10 = -5
8 - 10 = -2
10 - 10 = 0
12 - 10 = 2
15 - 10 = 5
Step 4: Find the sum of the difference:
Difference = (-5) + (-2) + 0 + 2 + 5 = 0
Step 5: Find the mean:
Mean = Assumed mean + difference
Mean = 10 + 0 = 10
Answer: The mean is 10
