Explicação
## Step 1:<br />To find the mean of a set of values, we add all the values together and then divide by the number of values. <br /><br />## Step 2:<br />To find the standard deviation, we first calculate the mean of the values. Then, for each value, we subtract the mean and square the result. The average of these squared differences is the variance. The square root of the variance gives us the standard deviation.<br /><br />## Step 3:<br />We apply these steps to each set of values.
