I'm so confused :(

U made Me confused

Do you know any who could help?

Ummmmmm @pooja165

@mathstudent55 can you help?

- anonymous

Yea they seem smart

@jim_thompson5910 please please please

- jim_thompson5910

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

- xxImHisGirlxx

yes

- xxImHisGirlxx

I think number 1 is A?

- jim_thompson5910

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

- jim_thompson5910

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

- xxImHisGirlxx

Number 2, D?

- jim_thompson5910

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

- jim_thompson5910

Ex of a discrete set: {1, 2, 3, 4, 5}
ex of a continuous set: the set of all real numbers

- xxImHisGirlxx

So, is number 2 C?

- jim_thompson5910

correct

- xxImHisGirlxx

Is number 3 B or D?

- jim_thompson5910

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?

- jim_thompson5910

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

- xxImHisGirlxx

Wait, is 3 A?

- jim_thompson5910

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

- xxImHisGirlxx

no

- jim_thompson5910

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

- xxImHisGirlxx

So, B?

- jim_thompson5910

yeah

- xxImHisGirlxx

I think 4 is A

- jim_thompson5910

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

- xxImHisGirlxx

So, a?

- jim_thompson5910

look back at #3

- xxImHisGirlxx

is 4 c?

- xxImHisGirlxx

and is 5 D?

- jim_thompson5910

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

- jim_thompson5910

so I agree with you. It is D

- xxImHisGirlxx

is 4 c?

- jim_thompson5910

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
