Question

3. For the following array of test scores, [99,58,87,78,100,100,91,93,78,66] Find the mean, standard deviation, minimum value, maximum value, and total number of scores using MATLAB's built-in functions (such as mean()) and tell the user these values. Note: In future problems, we may not allow you to use these built-in functions since they are specific to MATLAB (there is no mean() function in Fortran). However, it is important that you know these functions exist. If it is unclear whether or not you are allowed to use a built in function, please ask.

Explanation / Answer

scores = [99, 58, 87, 78, 100, 100, 91, 93, 78, 66];

fprintf('Mean is %f ', mean(scores))
fprintf('Standard deviation is %f ', std(scores))
fprintf('Minimum score is %f ', min(scores))
fprintf('Maximum score is %f ', max(scores))
fprintf('Toal number of scores is %d ', length(scores))
