Question

True or false: In a survey of your neighbors (asking for family size, the kind of pets they have, the grade of the youngest child in the family, the family's annual income in dollars, what the dad does for a living, whether mom works, and their phone number), the only discrete, numerical data you're collecting about your neighbors is family size.

Answer 1

Answer 2

your thoughts?

Answer 3

i think its false because the grade of the child should count as a number and the phone number is finite

Answer 4

you can't find the average grade (or do any kind of math on the grades)

the grade level is really a name or label

Answer 5

which value can you do math on (like compute the average) ?

Answer 6

the grades

Answer 7

no, you can't find the average grade

it makes no sense to say (grade 2 + grade 3)/2 = grade 1.5

Answer 8

ohh sorry i thought you meant if they were given a list of grades like 90, 92, 94 could you compute the average

Answer 9

is the income discrete numerical data?

Answer 10

yes, because you can compute the average income

Answer 11

and it makes sense to do so

Answer 12

"the only discrete, numerical data you're collecting about your neighbors is family size"

is false, it's not the only numerical data since income wasn't mentioned

Answer 13

ok thanks!
