As one variable increases, the other variable increases. What correlation is this?
What is Positive Correlation.
What is Inverse Variation?
The relationship between two variables.
What is a scatter plot?
Find the Percentage for 1/6.
16.67%
Solve for x.
6x + 10 = 4x + 65
27.5.
What is Correlation?
Correlation is the relationship between two variables.
Find the equation.
x 1 2 3 4 5
y 100 50 33 1/3 25 20
X * Y = 100.
What number is exactly increasing linear?
+0.3.
Find the percentage for 6/24.
25%.
Solve for X.
-7x + 8 = 5x + 98
X = -7.5.
As one variable increases the other variable decreases. What correlation is this?
Negative Correlation.
What is a Table Pattern?
The X value times the Y value always equals the same number.
What is an outlier?
A plot that is either much larger or much smaller than the other plots.
What is a function?
a relationship between inputs where each input is related to exactly one output.
Solve for X.
7x + 20 = 8x - 1
X = 19.
What is Correlation Coefficient?
How closely two variables are related to each other.
What is a Graph Pattern?
Decreasing curve with no X or Y Intercept.
What is a cluster?
A gathering or grouping of plots in a certain location.
What is a Linear Function?
A function that shows a straight line on the coordinate plane.
Solve for X.
10x + 50 = 18x + 70
X = 2.5
True or false: +0.3 is exactly linear increasing?
True.
What is the Equation Format for an Inverse Variation?
X * Y = K.
What are the 3 types of correlation a scatter plot can have?
Positive correlation, negative correlation and No correlation.
What is a Coefficient?
A number or any symbol representing a constant value that is multiplied by the variable.
