Algebra 1a- Lesson 3.6- Thursday, February 11, 2021 Name: Period: There are three different kinds of correlations: 1. Negative Correlation 2. No Correlation 3. Positive Correlation The Correlation Coefficient, or "r value", is the measure of how well a collection of data points can be modeled by a line. -1 Line with a negative slope fits best Perfect Negative Correlation No line fits because Line with a positive no pattern exists No Correlation slope fits best Perfect Positive Correlation 1. Lst the correlation coefficients in order from least to greatest: 0.79, -0.43, -0.4, 0.82, 0.08 2. If the corelation coefficient is .87, is its relationship considered to be strong positive, weak positive, strong negative, weak negative, or no correlation? 3. If the correlation coefficient is -0.03, is its relationship considered to be strong positive, weak positive, strong negative, weak negative, or no correlation? 4. Describe the correlation between hours worked at a job and the money eamed.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
