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
