Ur answer is here>>>>>=>
The standard deviation of a dataset gives you a measure of how spread out it is. On an average, it helps you ascertain how close each point is from the mean.
To understand this in a practical scenario, let’s look at test scores across two exams. Let’s say the mean for each is 70 and 80 points, out of 100, respectively. If the standard deviation is say, 5 for the first test and 10 for the other test, what can we say about the tests? We can say that the results for the second exam were more spread out, and that means that the test takers got scores vastly different to each other, in comparison to the first exam, in which the scores were packed more tightly.
