Define the array that is the result of the exam seven students who took the subject of Web services and have won 77, 98, 56, 87, 64, 55, 82 points. Print all of the results, the minimum and maximum number of points, compute the average winning score per student.
I am confused at min and max number of points, that is 100 right? so I need to count avarage number for example of 77 in percents or what, from 0 to 100, what avarage number, 77 is only number that student won
or I might need to set min and max from those numbers, but what next, its not avarage of all students together, but for every single student, student that won 77 points what is avarage for that, its 77
The min and max I assume would be from your sample. The average is just the sum of all values divided by the number of values - whether it is for all students or in the case of a single student, you would need all his/her values - which you do not specify. If you don't know which you need, I hardly think that we're in a position to tell you.
$points = array(7, 98, 56, 87, 64, 55, 82);
$min = min($points);
$max = max($points);
$ave = array_sum($points)/count($points); // you can format this with number_format()
