<h1>Afraid of Deviations, use Standard Deviation Calculator</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p>This article tells you about the ease at which you can solve our standard deviation problems, while using our standard deviation calculator. Math is a very vast subject. It is the study of space, relation, structure, change, and many other topics of pattern. It becomes an essential part in all the areas which includes engineering, social science, medicine, natural science etc. Online math tutors or various homework helper are available for all grades and college and university level students to provide math tutoring online.</p> <p>Now we are going to see the help of standard deviation calculator in solving our math problems. Standard deviation calculator solves statistical measure of spread or variability. It is an online statistics and probability tool for data analysis programmed to calculate common measure of the spread of a data set. The calculator is basically build to derive the standard deviation of a set of entered numbers. It will permit you to easily calculate the standard deviation. First question comes in our mind is that what is standard deviation? Standard Deviation is a measure of the dispersion of a set of data from its mean. The more spread apart the data, the higher the deviation.</p> <p>Standard deviation is calculated as the square root of variance. Before proceeding further let's see the basic behind variance. It is the average of the squared differences from the Mean. Standard Deviation is used to measure variability and it is basically used in statistics and probability theory. Its symbol is σ (the Greek letter sigma). The formula of Standard Deviation is the square root of the Variance. The formula comes with following elements:</p> <p>σ = standard deviation x = each value in population x with bar above = the value of the mean N = number of values. The ∑ symbol indicates that you must add up the sum. Means : (x1- x)2+ (x2- x)2+ (x3- x)2+ (x4- x)2+ (x5- x)2. . . + (xN– x)2. Standard Deviation = root of (x - x with bar above)2/N</p> <p>Chemistry is the study of the science of matter, especially its properties, structure, composition, behavior, reactions, interactions, and the changes it undergoes. chemistry help is a very renowned online tutorial and helping the students by completing their statistics based home work and assignments. To solve chemistry problem, there are various websites or Online Tutor available to provide assignments and projects on various subjects through email etc.</p> </p><strong>About the Author:</strong><br /><p>TutorVista is the #1 portal for learning <a rel="nofollow" href="http://math.tutorvista.com" title="tutoring online">tutoring online</a>.
