This video shows how to create a residual plot using a TI-84 Plus CE. I then describe what you should be aware of when looking at a residual plot. Residual plots are great tools in order to determine a least squared regression line's accuracy in modeling data.
This is the sixth video in a sequence of videos showing how to create a LSRL model for exponential data. The sequence of videos is based off my teachings of AP Statistics and doubles as an introduction into statistics at the college level.
The first video (found here • Graphing exponential d... ) is over entering data into a TI-84 Plus CE calculator, creating a scatter plot and interpreting the plot.
The second video (found here • Ratio of y's test for ... ) is over using the ratio of y's test in order to determine if a set of data is exponential.
The third video (found here • Re-expressing (transfo... ) is over re-expressing the data in a TI-84 Plus CE calculator in order to make it linear when plotted.
The fourth video (found here • Creating a linear mode... ) is over creating a least squared regression line (LSRL) on re-expressed data in a TI-84 Plus CE.
The fifth video (found here • Calculating and interp... ) is over finding and interpreting the correlation coefficient of the LSRL created previously.
The seventh video (found here • Predicting using a lin... ) is over predicting using a LSRL and stating confidence in such a prediction.
The eighth, and final video, (found here • Transforming a LSRL in... ) is over how to perform a transformation on the LSRL to place it in an exponential model form.
