Date:The Mian is MathematicallyOne of the most common uses of statistic is the determination ofthe mean value of a set of measurement. The term "Mean"IS. the statistical word used to state the "average" value of. a setof data. The mean is mathematically determined in the sameway as the "average" of a group of numbers is determined.The arthmetic mean of a set of N measurement, X,X2,X3 Xis equal to the sum of the measurement divided by the numberof data point N. Mathematically this is expressed by thefollowing equation.Inx=xnwhereX 1, the meann = the number of values (data)x, = the First data point X2 = the second data pointX1: the / data point.X,: the I data point ,X, = the first data point. X2 =the second data point etcThe symbol Sigma (I) is used to indicate summation, and i=1 to n indicates that the values of x, Fromi = 1 to i=nare added The sum is then elidi divided by the numberof terms added, n.Example: Determine the man of the following numbers:57134Solution :5a:-n1=15x,i=1
