Sentry CA700... | Answered on Jan 03, 2015


What is the question?
Put your calculator in STAT mode (2-var statistics or regression )
Enter your data in two lists, preferably sorted according to the x-value
Choose a regression model from the ones available and get the calculator to give you the best fit.
However to see which regression model best fits you data you need a graphing calculator to draw the scatter plot, then superpose on the scatter plot the curve of best fit given by the regression model.

Once you accept a model as the most suited one, you can use the equation of the curve to predict a y-value given an x-value (what ever REAL LIFE meaning they might have)
