mean of data 

To find the mean of a data set, we need to:

1. Add up all the numbers.
2. Divide the sum by the total number of values.

Let's calculate:

### Step 1: Add up the values.
\[
124 + 115 + 51 + 160 + 70 + 58 + 210 + 168 + 150 + 120 + 70 + 90 + 130 + 120 + 180 + 115 + 160 + 90 + 130 + 115 = 2426
\]

### Step 2: Count the number of values.
There are 19 numbers in the list.

### Step 3: Calculate the mean.
\[
\text{Mean} = \frac{2426}{19} = 127.68
\]

The mean of the data is approximately **127.68**.
