Bet you guys didn't remember this ... because I didn't HAHAHAHHAHA ...

NEGATIVE CORRELATION : this scatterplot shows a relationship that drops to the right. The independent variable is increasing and the dependent variable is decreasing.

ZERO CORRELATION : The dots on a scattorplot are scattered at random and do not resemble a line

LINE OF BEST FIT : This is the line that goes through the middle of your dots to show you the relationship

INTERPORLATION : Basically means to estimate the value of something that is not already given on the scattorplot.

FOR EXAMPLE : If it said on a chart that the sales increased every 5 days, for 25 days, and you wanted to figure out how high the sales were on the 14th day. That would be an interporlation.

EXTRAPORLATION : is to estimate the value of something that is not already give on the scattorplot and goes beyond the highest value

FOR EXAMPLE : If it said on a chart that the sales increased every 5 days, for 25 days, and you wanted to figure out how high the sales were on the 27th day , thats an extraporlation
