The question
Question: find the mean of 3, 4 and 4.
Mean of 3, 4, 4
The mean is the fair share.
We add them all, then share the total equally.
mean: add them all, then ÷ how many
1 Add them all
We add all the numbers, from left to right.
= 3 + 4 + 4
So the total is 11.
= total = 11
2 Count them
Now we count the numbers.
There are 3.
= how many = 3
3 Share equally
We share the total equally: 11 divided by 3.
= mean = 113
11 divided by 3 does not come out even.
It is 3.6667 and more digits.
11 ÷ 3 = 3.6667…
Rounded to 2 decimal places, the mean is about 3.67.
= mean ≈ 3.67
≈ means about
Let's look back.
First: add them all.
Then: count them.
Last: share equally.
Answer
≈ means about
