Scatter plot questions
100
An equation that includes the slope and y intercept of a line and makes a straight line when plotted on a graph.
What is a linear equation?
100
The amount of a y coordinate on a linear line expressed on an equation.
What does the m in the linear equation stand for?
100
pick two points that are plotted on your graph (not outliers) and find the slope of one to the other, make this slope the slope of your line of your linear line.
What are the steps for finding a line of best fit?
100
A graph with data points plotted on it.
What is a scatter plot?
100
The data on the graph is not following any pattern and does not look like a line at all.
What is a correlation coefficient far from 0 indicating?
200
y=mx+b
What is the linear equation before numbers have been plugged in to it?
200
A straight line.
What is a linear line?
200
A linear line that goes straight up vertically on the y axis forever and never increases or decreases on the x axis.
What is an undefined slope?
200
A number that tells how close the data points are in relation to each other on a graph.
What is a correlation coefficient?
200
The data looks like it is making a line of some sort and is following some kind of pattern.
What is a -.5 or a .5 correlation coefficient indicating?
300
The x coordinate of a line expressed in an equation.
What does the x in the linear equation stand for?
300
Finding the slope of the line by finding two points where the line lies on an x and y coordinate that is visible and obvious visually. In order to find the slope from the two points you have to find the difference in rise (y) and run (x)
What is one way that the graph a line is plotted on can help you find if the line is linear or not?
300
When the linear line can go forever on the x axis (run) but never up or down on the y axis (rise).
What is no slope?
300
The data is decreasing vertically.
What is a negative correlation coefficient indicating?
300
Data that is very close to making a linear line.
What is strong correlation?
400
The y coordinate on the linear line expressed in a linear equation.
What does the y in the linear equation stand for?
400
The amount of units that a line goes up or down every time it goes a certain amount of units left or right.
What is the slope of a line?
400
A graph with non linear data plotted on it.
What is a line of best fit made on?
400
The data is increasing vertically.
What is a positive correlation coefficient indicating?
400
The data points are not in a pattern or line form on the graph?
What is a weak correlation coefficient indicating?
500
The y intercept of a linear line expressed in an equation.
What does the b in the linear equation stand for?
500
The y coordinate where the line crosses the y intercept, the x coordinate is 0.
What is the y intercept?
500
Data.
What is plotted on a scatter plot?
500
That the data is not close to making a linear line.
What is a correlation coefficient close to 0 indicating?
500
A linear line that describes non linear data as accurately as possible.
What is a line of best fit?
