The video tutorial covers how to create scatter plots using graphing calculators. It begins with data entry and setup, followed by graphing and adjusting the viewing window. The tutorial explains how to calculate the line of best fit and demonstrates interpolation and extrapolation. Examples include cricket chirps related to temperature and Ironman Triathlon data. The lesson concludes with assignment instructions.

What is the first step in creating a scatter plot on a graphing calculator?

• Turn on the calculator and press the 'Graph' button.

• Turn on the calculator and press the 'Stat' button.

• Turn on the calculator and press the 'Window' button.

• Turn on the calculator and press the 'Mode' button.

What is interpolation?

• Calculating the exact values of data points.

• Estimating values within the range of data points.

• Estimating values outside the range of data points.

• Ignoring outliers in the data set.

What is the main difference between interpolation and extrapolation?

• Interpolation is used for linear data, while extrapolation is used for non-linear data.

• Interpolation requires manual calculation, while extrapolation uses the calculator.

• Interpolation is more accurate than extrapolation.

• Interpolation uses data points within the range, while extrapolation uses data points outside the range.
