This video shows how to perform a ratio test on dependent variable data points in tandem with their independent values to determine if the data could be exponential. This is not the only test in order to determine if data is exponential.
This is the second 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 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 sixth video (found here • Creating a residual pl... ) is over creating a residual plot using a TI-84 Plus CE and interpreting the plot.
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.
