Answer:
mean = 31.4
Step-by-step explanation:
The mean of a group of values is calculated as
• mean = ( sum of values ) ÷ ( number of values )
given the number of values is 5 , that is
18 , 18 , 33 , 34 , 54
sum = 18 + 18 + 33 + 34 + 54 = 157
Then
mean = 157 ÷ 5 = 31.4
Answer:
31.4
Step-by-step explanation:
To calculate the mean you have to add the numbers to find the total and then divide that answer by the number of variables.
So we would do:
1. 18 + 18 + 33 + 34 + 54 = 157
2. 157 ÷ 5 = 31.4
(We divide by 5 because that's how many numbers we added to get the total)
