The set of numbers that you must use is as follows: Standard Deviation – The measure of variance (or dispersion) from the mean.Mean – The mean or average of the numbers in the data set.Count – Quantity of numbers in the data set.Using the StatCalc class, write a program that calculates and then displays as output to the console, the following statistics against the set of numbers given below. Return Math.sqrt( squareSum/count - meanmean ) * Return the standard deviation of all the items that have been entered. * The return value is Double.NaN if no numbers have been entered. * Return the average of all the items that have been entered.
* Return the sum of all the numbers that have been entered. * Return the number of items that have been entered into the dataset. * the numbers that have been added to the dataset using this method. Private double squareSum // The sum of the squares of all the items. Private double sum // The sum of all the items that have been entered. Private int count // Number of numbers that have been entered. * of items, the sum of the items, the average, and the standard deviation * statistics for the set of numbers that have been entered: The number Methods are provided to return the following Numbers are entered into the dataset using * An object of class StatCalc can be used to compute several simple statistics Import statement: An import statement tells the compiler the path of a class or the entire package.
