@hartnn :>
OpenStudy (anonymous):
I think it's C or D
hartnn (hartnn):
definition of marginal freq ?
OpenStudy (anonymous):
Marginal freq is on the edges of the table

OpenStudy (anonymous):
I'm just not too sure what the RELATIVE marginal freq is
hartnn (hartnn):
is 62 on the edge ?
OpenStudy (anonymous):
Yes, it is
hartnn (hartnn):
whats the definition of relative marginal ?
OpenStudy (anonymous):
I'm not sure

Let me check my notes
OpenStudy (anonymous):
A marginal relative frequency is found by dividing a marginal frequency by the whole sample size.
OpenStudy (anonymous):
What is the sample size
OpenStudy (anonymous):
I'm not sure what that means D:
hartnn (hartnn):
if that experiment was done among 100 students
then 100 would be your sample size

OpenStudy (anonymous):
Ah, ok
OpenStudy (anonymous):
So all the numbers added up?
OpenStudy (anonymous):
Wait,that's wrong
OpenStudy (anonymous):
I think it would be D
hartnn (hartnn):
so assuming 100 students are there in total
62 will like new york

Since it's in the form of a percentile
hartnn (hartnn):
marginal freq = 62
sample size = 100
marginal relative freq = 62/100 =0.62 = 62%
OpenStudy (anonymous):
I knew it >:D
hartnn (hartnn):
yes, thats right :) since its in %, its relative!
OpenStudy (anonymous):
One more thing?

OpenStudy (anonymous):
Just want you to check this for me
hartnn (hartnn):
sure
OpenStudy (anonymous):
hartnn (hartnn):
in this "relative" frequency table is asked, not the freq table
OpenStudy (anonymous):
So, it wouldn't be a whole number

hartnn (hartnn):
so just divide EVERY entry by the sample size = total number = 360
OpenStudy (anonymous):
Divide every entry by 360?
hartnn (hartnn):
every entry of freq table, yes
hartnn (hartnn):
because 360 is the sample size
OpenStudy (anonymous):
Okay, thanks :D

welcome ^_^
OpenStudy (anonymous):
I'll tell you if i need more help :>
hartnn (hartnn):
so you'll get B for that
hartnn (hartnn):
sure, always happy to help :)
OpenStudy (anonymous):
@hartnn It's B, it looks like.

:D
OpenStudy (anonymous):
This next two questions are strange wording
hartnn (hartnn):
words are strange only till you don't know their meaning.
OpenStudy (anonymous):
This is the first one. I don't know about these defintions :

"Possible positive associations"
hartnn (hartnn):
I am new to those terms too
OpenStudy (anonymous):
Let me see if someone else asked this BRB
OpenStudy (anonymous):
No lcuk

Yay, more people :D
OpenStudy (anonymous):
Maybe it's B
hartnn (hartnn):
see the last attachment only....no need to go through comments...
OpenStudy (anonymous):
I can reattach it, gimme a sec

Use that one :>
OpenStudy (anonymous):
But yeah I think it may be B, since that's a true answer
