If a scatterplot has a no association, what does it look like?
scattered (all over the place)
no trend noticeable
What are two qualities a lie of best fit for scatterplot must have?
1. The slope of the line must follow the trend
and
2. The line must be placed in the middle of the data points

DOUBLE POINTS: How does a scatterplot that has a positive association differ from a scatterplot that has a negative association?
A scatter plot with a positive association, all the points are trending in a upward position (as the x values go up, the y-values are going up) but in a scatterplot with a negative association, all the points are trending in a downward position (as the x values go up, the y-values are going down)
What are the steps to calculating the line of best fit?
1. Find two points that are ON the line of best fit
2. Find the slope/ROC (change in y/change in x-values) = m
3. See where the line meets the y-axis = b
4. Substitute the ONLY values for m and b into the format y=mx+b

What makes a scatterplot have a linear vs having a nonlinear association?
In a linear association , data points formulate a line.
How do we make predictions using the line of best fit?
Identify the value for which you want to make a prediction on the line of best fit. OR Plug in the value for in the equation of the line of best fit.

What does an outlier look like on a scatterplot?
It is a point on the graph that doesn't follow the trend.
"out"cast
The points (0,50) (2, 30) and (4,10) are on the best line of fit. Use the points to determine a linear equation that can represent it.
y = 10x + 50

What is the difference between a weak and strong linear association?
The stronger the association the closer it looks like a line. The weaker the association the more scattered the data points are
If y=-1x + 4 represent the line of best fit that compares hours of playing video games the night before your state exam and the raw score on the state exam, what do you know about their relationship?
If you play no video games the night before, you can get a 4 on your state exam. For every hour that you play for video games, your raw score for the state exam will decrease by 1.
