I was hoping someone could help explain this I saw an answer and the step by step included this in it

When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. **Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.**

In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.

I put 2 stars around the part that Im talking about, but I was wondering if someone could explain it a bit more thanks :)

i think it means everything depends on the answers you get and also depends on what your trying to answer

Step-by-step explanation:

sorry that's just what i took in from that part

hope this helps :)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
