Answer:
mean is 5
Explanation:
MEAN
mean is regarded as the average number of items
mean formula:
(sum of terms) / (number of terms)
Firstly
the numbers in the data set are :
3,3,3,4,6,6,7,8
they are already arranged in order, so no need to rearrange.
Next
add the numbers together to find the total :
3 +3 +3 +4 +6+ 6+7 +8
= 40
ALSO,
find how many number of terms they are --- this is 8
Last
use the mean formula to solve :
(sum of terms) / (number of terms)
= 40/8
= 5
the mean is the 5
