Unit #1-07

Learning Outcome

At the end of this lesson, you will be able to:

• create an application that uses 2D arrays

Review

• reading a file

Lesson

• what is the Normal Distribution

  • seriously, take MDM4U and / or statistics after high school

  • oddly enough, machine learning is just computer statistics!

Daily Assignment

• read the following problem:

  • create a "Marking" application like this:

    • read in a text file with a list of students

    • read in a second file with a list of assignments

      • use both as arguments being passed in

        • note: the arguments are an array!

    • I really dislike marking! so ...

    • create a program that will randomly generate all the marks

      • the mean should be 75 and the standard deviation should be 10

        • see above Normal Distribution

          • see examples below

        • the marks MUST be integers

    • save the results in a 2D array

      • the functions takes in 2 parameters and passes back a 2D array, of strings (names and assignments as row and column headers and marks in the middle)

      • output the results in a CSV file called marks.csv

Extra

• do the above in a second language
