Classwork
Apologies everyone, but I messed up! Mayah pointed out to me after the quiz on Wednesday that I had never assigned the vocabulary words from Big Idea 2: Data. Indeed that is the case, and it means it wasn't fair to give you the quiz last class.
A few of you asked in class if there would be a chance to retake this quiz, and now I can understand why. So, to adjust for my mistake, we will treat the quiz on Wednesday as practice, assign the vocabulary for homework tonight, and take a different quiz on data concepts when you come to class on Tuesday.
Here are the correct answers for the practice
quiz:
1:A 2:B 3:D 4:C 5:A 6:A 7:C 8:C 9:A 10:B 11:C 12:B 13:D 14:C 15:B 16:B 17:D 18:D 19:A 20:C 21:C 22:B 23:D 24:B 25:B 26:B 27:D 28:B
27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 |
128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
Decimal | Binary | Hex |
---|---|---|
0 | 0000 | 0 |
1 | 0001 | 1 |
2 | 0010 | 2 |
3 | 0011 | 3 |
4 | 0100 | 4 |
5 | 0101 | 5 |
6 | 0110 | 6 |
7 | 0111 | 7 |
8 | 1000 | 8 |
9 | 1001 | 9 |
10 | 1010 | A |
11 | 1011 | B |
12 | 1100 | C |
13 | 1101 | D |
14 | 1110 | E |
15 | 1111 | F |
During class today we will talk more about data and data mining concepts,
review the practice
quiz you took last class, and I will introduce
you to the
DRY principle in software design, illustrating it with the survey
program that Group D shared with us.
Homework
Add a Markdown to
your git repo named Data.md
.
Write your own definitions for each of the vocabulary words listed in Jelkner's Big Idea 2: Data notes.
This assignment is due Monday, February 13th at 5:00 am. NOTE: It seems
many of you got out of the habit of turning in homework like this
on time. While there will be a cost, if I see the
ComputingSystemsAndNetworks.md
file assigned last class, I will
change your grade from 5 to 8.
