High School Math based on the topics required for the Regents Exam conducted by NYSED. These lessons cover Scatterplots and Linear Regression in Statistics.

Scatterplots & Regression on the TI-84

This video shows how to input two variable data and create a scatterplot with the TI-84 calculator. We talk about looking at the data to decide what type of regression is appropriate. Then we perform linear regression on the data. Then, we graph the linear regression equation with the scatterplot data.



Linear Regression

How to do (linear) regression on the TI-83/84 with extra tips on plotting the regression function/equation easily.

Least Squares Linear Regression

This video shows you how to generate a least squares linear regression model on the TI-84.


 

Scatter Plots

This video shows how to plot data and use the linear regression feature in TI83 and TI84 series graphing calculators to create a line of best fit. Also, analysis using the generated line of best fit is demonstrated.
