## Scatter Plots and Trend Lines

Objective:

- To write an equations of a trend line and of a line of best fit
- To use a trend line and a line of best fit to make predictions

I CAN create a scatter plot from two quantitative variables.

I CAN describe the form, strength and direction of the relationship.

I CAN use the function to predict values.

I CAN use a calculator or computer to find the correlation coefficient for a linear association and interpret the meaning of the correlation coefficient in the context of the data.

I CAN explain the difference between causation and correlation.

### Standards

Standards

- MAT-HS.S-ID.06 Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
- a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data.
- c. Fit a linear function for a scatter plot that suggests a linear association.

- MAT-HS.N-Q.01 Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
- MAT-HS.F-LE.05 Interpret the parameters in a linear, quadratic, or exponential function in terms of a context.
- MAT-HS.S-ID.07 Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
- MAT-HS.S-ID.08 Compute (using technology) and interpret the correlation coefficient of a linear fit
- MAT-HS.S-ID.09 Distinguish between correlation and causation.
