Question

find the mean of:
19 25 23 3 1 17 32 33
3 9 28 21 7
mean =

Explanation:

Step1: Count the number of data points

First, we count how many numbers are in the list. Let's list them out: 19, 25, 23, 3, 1, 17, 32, 33, 3, 9, 28, 21, 7. Let's count: that's 13 numbers.

Step2: Calculate the sum of the data points

Now we add all these numbers together:

$$

$$

Step3: Calculate the mean

The mean is the sum divided by the number of data points. So we divide the sum (221) by the number of data points (13):

$$ \text{Mean} = \frac{221}{13} = 17 $$

Answer:

17
