+// Let's try to develop a program which calculate measure of central tendency of a sample(mean, median, mode) 
+// and measure of variability(range, variance, standard deviation). In addition to those measures find the min, max, count, percentile,
+// and frequency distribution of the sample. You can create a class called Statistics and create all the functions which do statistical 
+// calculations as method for the Statistics class. Check the output below.
