Answer 2

What is this

Answer 4

That Explains why my brain just exploded

Answer 5

I'm so confused :(

Answer 6

U made Me confused

Answer 7

Do you know any who could help?

Answer 8

Ummmmmm @pooja165

Answer 9

@mathstudent55 can you help?

Answer 10

Yea they seem smart

Answer 11

@mathmate

Answer 12

@jim_thompson5910 please please please

Answer 13

The instructions are missing, but I'm assuming they want you to identify the type of variable? That's what it looks like

Answer 14

yes

Answer 15

I think number 1 is A?

Answer 16

letter grade in algebra (1 point)
qualitative/ordinal
qualitative/nominal
quantitative/discrete
quantitative/continuous


think about what types of grades are possible: A,B,C,D,F

now think to yourself: does it make sense to order these? The answer is yes because A comes before B, B before C, etc. Put another way, A has a higher "value" than B. B is higher than C, etc. This all means grades are ordinal.

The grades are qualitative because they aren't numeric values. If they were numeric values that you could do math on, then it would be quantitative

Answer 17

`I think number 1 is A? `
yeah I agree

Answer 18

Number 2, D?

Answer 19

If it were continuous, you'd have a spectrum instead of a few tax brackets. That would make the tax code probably more complicated

Since there are only a few tax brackets, we have discrete data. When something is discrete, it is countable. You can list all of the elements and it doesn't go onto infinity

Answer 20

Ex of a discrete set: {1, 2, 3, 4, 5}

ex of a continuous set: the set of all real numbers

Answer 21

So, is number 2 C?

Answer 22

correct

Answer 23

Is number 3 B or D?

Answer 24

what are some of the political parties out there? Can you list them out and not go off to infinity? Can you do math on the elements in this set?

Answer 25

Also, does it make sense to order the political parties?

Answer 26

Wait, is 3 A?

Answer 27

does it make sense to order the political parties? Assume you aren't biased towards any one party

Answer 28

no

Answer 29

I guess you could order based on the political spectrum (democrats on left, republicans on right) but there are many parties than just those two. So it doesn't make much sense to order them. In this case, the data is nominal

nominal means "name" more or less. The data is just a bunch of name labels

Answer 30

So, B?

Answer 31

yeah

Answer 32

I think 4 is A

Answer 33

The colors could be sorted alphabetically, or by the color spectrum. However, ordering the colors doesn't seem to make sense. So it's very similar to the previous question

Answer 34

So, a?

Answer 35

look back at #3

Answer 36

is 4 c?

Answer 37

and is 5 D?

Answer 38

5. length of a caterpillar (1 point)
qualitative/ordinal
qualitative/nominal
quantitative/discrete
quantitative/continuous


since we're able to measure the length of the caterpillar, and that length is numeric, it is quantitative. It's possible to have lengths like 1.2 cm or 1.12 cm or 1.102 cm. The possibilities are endless in terms of how precise we get. There are infinitely many numeric values possible. So this data is also continuous. Think of a number line

Answer 39

so I agree with you. It is D

Answer 40

is 4 c?

Answer 41

no, colors are qualitative and nominal

qualitative because you can't do numeric operations on "red", "green", etc
nominal because the colors are just labels
