After the user inputs a set of data, I need to output the mean, median, and mode; I tell them to input the numbers, with each number separated by a q, so I can easily use arrays. MAke sure the array is parse'd.
Mean - split the array at the separation character. Create a loop, where I set a variable equal to the current case of the array, added with the sum of all the previous cases of the array. When it gets to the end, take the sum of all the previous cases of the array and the last case of the array, and divide that by the length of the array.
Mode - split the array at the separation character. Sort the resulting numbers from lowest to highest. Honestly, I have no idea how I would economically figure out the most occuring number in my array.
Median - take the length of the array, and if the module of the array is 0, display the number (after its been sorted) that is at the index of the length of the array divided by 2. If the module is 1, take the average of half the index of the length of the array +1, and the index of the array -1.
document.write the number out.
