What is the difference between interpolation and extrapolation?

• Interpolation = predicting the x value. Extrapolation = predicting the y value.

• Interpolation = predicting values within the dataset range.

  Extrapolation = predicting values outside the dataset range.

• Interpolation = data that lands on the LSRL

  Extrapolation =

  data that is not on the LSRL

• Interpolation = existing data

  Extrapolation = estimated values

How confident are you in bivariate data analysis?

• I'm not too sure about some of the terms and concepts. I want to go over some things again.

• I'm not familiar with the technology that I can do an analysis with. I want to review them again.

• I'm ready for some investigation. I want to find out what else to improve while problem-solving.

• I haven't been doing much work, therefore I'm not sure how well I know the topic.

• I get the concepts and the basic procedures. I'm ready to sharpen my skills through contextual investigations.
