Answer:
The answer is below
Step-by-step explanation:
The standard deviation formula is as follows:
where sum means "sum of", x is a value of a data set, m is the mean of the data set, and N is the number of data.
The standard deviation formula may seem confusing, but it will make sense after we break it down. In subsequent sections we will explain an interactive example, step by step. Here's a quick preview of the steps we're about to follow:
Step 1: Calculate the mean with the data from the graph.
Step 2: Calculate the square of the subtraction between the mean and each data (that is, each x).
Step 3: add the values that resulted from step 2.
Step 4: divide by the number of data.
Step 5: take out the square root.
And in this way you can obtain the standard deviation
