Identifying Variables...

[joeypeter]

Identify whether the following variables are numerical or categorical. If numerical, state whether it's discrete or continuous. If categorical, state whether variable is nominal or ordinal.

a) number of sexual partners in a year
b) petal area of rose flowers
c) key on the musical scale
d)heart beats of cyclist, averaged over duration of race
e) stage of fruit ripeness
f) angle of flower orientation relative to position of sun
g) tree species
h) year of birth
i) gender
j) birth weight

I've been trying to do this problem for a while, so could someone help please?

What are the definitions of "numerical" and "categorical" variables?

When you reviewed each description, what did you conclude? Was it measuring something numerically, or was something just being categorized?

Please reply with your thoughts and answers so far. Thank you!
