Pulse rate is something you can measure and it has a continuous range of values, so I'd say it's numerical.
If we instead had something like "low", "medium" and "high", that would be categorical.
@devout fossil Like How do i know which one is the explanatory and response variablae
I don't understand what you're talking about. We have boxplots of two random variables: pulse rate of women and pulse rate of men.
yes it says identify the each of the variable
like the type of variable
is it explanatory or response
Hm... Haven't heard of that classification. Let me find some info on it first.
is the same as indepdednent and depdendent variable
Well, they certainly don't depend on each other. So, I think they are both explanatory.
how?
Well, the pulse rate of one gender doesn't influence the other.
then what are we me measuring
Pulse rate of each gender.
@devout fossil we have to be either be measuring pulse rate or gender
does the type of gender change the pulse rate
or does the pulse rate hae a connection with the gender
Oh, that's what you meant!
isn't that what the indepdenent and depdendent variable is..
Hm... Well, we can make hypotheses about that.
Yeah, sorry. I'm more used to that in chemistry, where the dependence is numerical, not categorical.
Well, in this case I guess we have gender, which is explanatory, and pulse rate, which is response.
how though
that's what i think too
but how do you prove it's not the other
how can you be 100% sure
Well, that depends on whether there is even a relation.
Suppose the pulse rate is X(g), where g = 0 for men and 1 for women. Then the distribution of X(g) might depend on g. Or maybe it doesn't.
If it does, though, we can then measure the pulse rate of an arbitrary person and make a hypothesis about their gender; so, we now determine g in terms of a sample from X.
