Would you be able to share what presentation software you used, and if you used a light pen (or whatever they are now called) or a mouse to draw in the X,Y, the data points and the lines? I'm developing my own mini-lectures and am interested in the technologies others are using.

@spaceinkfilms

I use a Bamboo tablet and pen to do the screen writings, which I create in One Note and record using Camtasia. It might not be the best method but it worked for me. Good luck with your mini-lectures.

Are the data sets the raw data or data after the raw data has been manipulated.

It seems the lateer.

What I am saying is using this vid in isolation is a little confusing.

I just know you agree. lol

well by saying "correlation shows a relation between variables", then i simply can't agree that in the fourth drawing there is no correlation. there's no bijective correlation, i agree, but there's a correlation. If i see a parable in the drawing, there's definetelly something going on there, some way the variables influence each other. Not in a linear way, but correlations aren't about liniarity, but about influence.

So that fourth case - i don't agree with you.

[bebilda]

@De4sher what she is trying to say is that the Pearson's correlation coefficient rho=0 = not linear relationship, because she is using r (rho)..but of course there´s a relationship that in nonlinear.

[speedyresx]

Fantastic explanation! Thank you so much!

[stiaa04]

Can we say when there is no correlation that the variables are NOT affecting eachother or is that equally uncertain as the opposite case?

[BeeTruthful]

i understand this in my psyc course now . thank you !

uhhmm, about your fourth example of direction, if its a curve it is just called a non-linear. tried to research about it because my teacher told me that it still has a relationship but not linear. thanks though, you made it a little easier for me about correlation direction and strength
