p {margin: 0; padding: 0;} Date: The Mian is Mathematically One of the most common uses of statistic is the determination of the mean value of a set of measurement. The term "Mean" IS. the statistical word used to state the "average" value of. a set of data. The mean is mathematically determined in the same way as the "average" of a group of numbers is determined. The arthmetic mean of a set of N measurement, X,X2,X3 X is equal to the sum of the measurement divided by the number of data point N. Mathematically this is expressed by the following equation. I n x = x n where X 1, the mean n = the number of values (data) x, = the First data point X2 = the second data point X1: the / data point. X, : the I data point ,X, = the first data point. X2 = the second data point etc The symbol Sigma (I) is used to indicate summation, and i =1 to n indicates that the values of x, Fromi = 1 to i=n are added The sum is then elidi divided by the number of terms added, n. Example: Determine the man of the following numbers: 57134 Solution : 5 a :- n 1=1 5 x, i=1
The Mean is Mathematically
