What is the mean? \[ \begin{array}{llllllllll}0.65 & 0.84 & 0.11 & 0.91 & 0.66 & 0.01 & 0.98 & 0.91 & 0.92 & 0.0\end{array} \]

To find the mean of the given set of numbers, you first add all the numbers together and then divide by the count of numbers. Here, the numbers are \(0.65, 0.84, 0.11, 0.91, 0.66, 0.01, 0.98, 0.91, 0.92, 0.0\). When you add them up, you get \(6.15\). There are 10 numbers in total, so you divide \(6.15\) by \(10\) to get a mean of \(0.615\). Finding the mean is like slicing your favorite cake into equal pieces to share with friends! You want to ensure everyone gets a fair share when you sit down to enjoy it together. Just remember, if one person takes a bigger slice (or if you have outliers in your numbers), it might skew the whole cake experience (mean), making some feel shortchanged! For checking your mean calculation later, consider using software or calculators which allow for easy entry and processing of your data. Mistakes often happen when adding by hand, especially with decimals. Double-check your sum and don't hesitate to run the data through an online calculator for confidence!
