\n[00:00:05] if two variables have a \u201cnear zero\u201dcorrelation and you therefore conclude they are unrelated, you are also concluding they are: a)independent of each other b) perfect predictors of each other c) dependent upon each other d)all of the above<\/p>\n

Tutor<\/strong>
\n[00:00:10] Welcome!\u00a0My name is Anahid, How are you?<\/p>\n

Student<\/strong>
\n[00:00:44] hello im great how are you?<\/p>\n

Tutor<\/strong>
\n[00:01:04] I’m great too! Thanks
\n[00:01:11] Tell me, what can I do for you today?<\/p>\n

Student<\/strong>
\n[00:01:34] i wrote the problem up there ^
\n[00:01:39] i dont know what to do<\/p>\n

Tutor<\/strong>
\n[00:02:00] are you familiar with the concept of correlation?<\/p>\n

Student<\/strong>
\n[00:02:09] yes somewhat.<\/p>\n

Tutor<\/strong>
\n[00:02:31] can you tell me what correlation means?<\/p>\n

Student<\/strong>
\n[00:03:35] its a relationship or connection between two things
\n[00:03:41] if they are related or not..<\/p>\n

Tutor<\/strong>
\n[00:03:52] that’s right!
\n[00:04:08] the correlation express the relation between two variables
\n[00:04:22] so if there is an almost zero correlation
\n[00:04:31] what that means?<\/p>\n

Student<\/strong>
\n[00:04:57] there is no correlation<\/p>\n

Tutor<\/strong>
\n[00:05:05] that’s right
\n[00:05:07] !
\n[00:05:25] here is a web site that can help use to see it better<\/p>\n[00:05:48] \u00a0http:\/\/stattrek.com\/statistics\/correlation.aspx?Tutorial=Stat<\/a><\/p>\n

Student<\/strong>
\n[00:05:59] ok great, thanks!<\/p>\n

Tutor<\/strong>
\n[00:06:14] can you see the graphs?<\/p>\n

Student<\/strong>
\n[00:06:23] yes<\/p>\n

Tutor<\/strong>
\n[00:06:28] look at the one that says zero correlation
\n[00:06:49] we have two variables, each one represented by an axis
\n[00:07:35] can we predict one from the other?<\/p>\n

Student<\/strong>
\n[00:07:56] theyre not related?<\/p>\n

Tutor<\/strong>
\n[00:08:07] that’s right
\n[00:08:36] we can not predict one from the other
\n[00:08:49] those dots are random
\n[00:09:03] Does this problem make sense to you now?<\/p>\n

Student<\/strong>
\n[00:09:27] yes
\n[00:09:38] but i dont get what independent
\n[00:09:42] or dependent mean<\/p>\n

Tutor<\/strong>
\n[00:10:15] dependent means that the value of one variable depends on the value of the other
\n[00:10:23] independent is the opposite
\n[00:10:38] it means that the variables are not related<\/p>\n

Student<\/strong>
\n[00:10:48] oh so a?
\n[00:10:51] independent<\/p>\n

Tutor<\/strong>
\n[00:10:56] does this sound familiar to you?
\n[00:11:03] Great job on that one! Nicely done.<\/p>\n

Student<\/strong>
\n[00:11:02] yes<\/p>\n

Tutor<\/strong>
\n[00:11:15] Perfect!\u00a0 Good work.
\n[00:11:21] Do you have any questions about anything we went over today?<\/p>\n

Student<\/strong>
\n[00:11:24] thank you!
\n[00:11:30] no thats it<\/p>\n","protected":false},"excerpt":{"rendered":"
