**Programming Practice**

Given a sequence of *
n* elements, *
x*_{1},
*x*_{2},
¼,
*x*_{n-1},
*x*_{n},
the mean (m) and
the standard deviation (s)
are defined as:

respectively. Suppose there are
15 students. Read the score of theses students (0 to 100) and compute the mean
and standard deviation of the scores.

Enter the score of student No. 1:
78
Enter the score of student No. 2:
65
Enter the score of student No. 3:
90
Enter the score of student No. 4:
52
Enter the score of student No. 5:
84
Enter the score of student No. 6:
95
Enter the score of student No. 7:
72
Enter the score of student No. 8:
68
Enter the score of student No. 9:
54
Enter the score of student No. 10:
80
Enter the score of student No. 11:
75
Enter the score of student No. 12:
93
Enter the score of student No. 13:
54
Enter the score of student No. 14:
81
Enter the score of student No. 15:
70
The mean is 74.07.
The standard deviation is 13.35. |
