M. 2. 3.- Explain the relationship between two variables

Variable

Represents a quantity that can truly vary

Independent variable

A variable that determines the value of another variable

Dependent Varible

A variable that depends on at least one other variable

Axis

A reference line for measurement of coordinates

Correlations

The way two variables change together/also known as a covariation

Positive

If both variables increase, what is the correlation where the variables are directly related

Negative

If one increases and the other decreases what is the correlation where the variables are inversely related

direct variation

two variables increase and decrease at the same rate

Y=kx

direct variation formula where k is the constant or proportionality

Inverse Variation

When an increase or decrease in one variable produces a decrease or increase, respectively, in another variable

Y=k/x

inverse variation formula

Shape

Symmetry, number of peaks, skewness, and uniformity of data distribution
