Example Question #1 : Standard Deviation
Calculate the standard deviation of the following data set:
Cannot be determined
The standard deviation is found by using the following formula:
We will start by identifying the components of this equation:
Now, we can use this information to calculate the standard deviation.
First, we need to identify and . There are six variables in the data set; therefore, we can write the following:
Next, we need to calculate the mean:
Second, we need to find the square of the absolute of each variable minus the mean:
Last, let's substitute these values into the standard deviation formula and solve.
