## Calculating Mean and Standard DeviationIn this tutorial, we will learn how to calculate the mean and standard deviation for a sample dataset. Let’s take the following set of sample data and calculate the required values by hand, rounding all values to four decimal places where possible:**Sample Data:**11, 5, 3, 12, 4### Step 1: Calculate the MeanThe mean (average) of a data set is found by adding all the numbers together and dividing by the number of data points. This can be expressed as follows:\[\bar{x} = \frac{\sum x}{n}\]Where:- \(\sum x\) = sum of all data points- \(n\) = number of data pointsFor our sample data:\[\bar{x} = \frac{11 + 5 + 3 + 12 + 4}{5}\]\[\bar{x} = \frac{35}{5} = 7.0000\]### Step 2: Fill in the TableNext, we will prepare a table to help us calculate the deviations of each data point from the mean, and the square of these deviations. The columns in the table are:- \(x\): the data points- \(x - \bar{x}\): the deviation of each data point from the mean- \((x - \bar{x})^2\): the square of each deviation| \(x\) | \(x - \bar{x}\) | \((x - \bar{x})^2\) ||-------|--------------|-----------------|| 11 | | || 5 | | || 3 | | || 12 | | || 4 | | || **Total** | | |Let’s fill in the missing values:| \(x\) | \(x - \bar{x}\) | \((x - \bar{x})^2\) ||-------|--------------|-----------------|| 11 | 4 | 16 || 5 | -2 | 4 || 3 | -4 | 16 || 12 | 5 | 25 || 4
