PLEASE EXPLAIN ALL THE STEPS YOU TAKE AND DESCRIBE WHAT EXACTLY EACH INSTRUCTION DOES?

Bonus: Write 80x86 assembly language program that takes statistical data (n samples) and calculate the mean, median and variance of the samples. Assume the data is only a single digit number (0-9), but ASCII encoded. The program should take samples until the "enter" key is pressed, then it should process the data and display the result. Use macros and/or subroutines to organize your code. In addition, every line should be commented
