Frequency Table, help please.

@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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

hartnn (hartnn):

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.

hartnn (hartnn):

yes it is :)

OpenStudy (anonymous):

: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 :

OpenStudy (anonymous):

"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

hartnn (hartnn):

@zepdrix @dan815 @shamil98

OpenStudy (anonymous):

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

OpenStudy (anonymous):

OpenStudy (anonymous):

Use that one :>

OpenStudy (anonymous):

But yeah I think it may be B, since that's a true answer
