To calculate the mean, add all the numbers together and then divide by the total count of numbers.

Given dataTo calculate the mean, add all the numbers together and then divide by the total count of numbers.

Given
$65, 58, 40, 35, 60, 55, 52, 46, 73, 66$

Step 1: Find the Sum of All Values

$65 + 58 + 40 + 35 + 60 + 55 + 52 + 46 + 73 + 66 = 550$

Step 2: Count the Total Number of Values

There are 10 values.

Step 3: Calculate the Mean

$\text{Mean} = \frac{\text{Sum of values}}{\text{Total number of values}} = \frac{550}{10} = 55$

So, the mean is 55.

Would you like me to find the median and mode as well, or provide further details?

1. What is the median of a dataset, and how is it found?
2. How do you calculate the mode in a dataset with multiple values?
3. What would happen to the mean if we added another value to this dataset?
4. Can the mean be lower than the smallest number in a dataset?
5. How does an outlier affect the mean of a dataset?

Tip: In a dataset with an even number of values, the median is the average of the two middle numbers.
