Lab 2 No data is required. Here is a short video about Anscombe's quartet, which may be useful for lab#2. https://www.youtube.com/watch?v=Ftp3mmItV-k 1)
X-axis variable name: Elongation Y-axis variable name: Force 2)
Name of the unit on the X-axis: Cm Name of the unit of the Y-axis: Force N 3)
Calculate the scale: x-axis scale calculation: 1/10 = 0.1cm y-axis scale calculation: 5/5= 1N 4)
Fill the following table with the values of elongation and force for the first and last data points. First data point last data point Elongation ( cm ): 2 cm 10N Force ( N ): 8cm 42N 5)
What value of force is predicted by the trendline for the elongation value listed below? Elongation ( cm ) 7 Predicted Force ( N ) 36 6)
What value of elongation is predicted by the trendline for the force value listed below? F Force (N ) 35 Predicted elongation (cm ) 6.9 7)
Calculate the slope of the trendline. Indicate below the coordinates of the points that you will use to calculate the slope. Point 1 coordinates: (elongation 1, force 1) = ( ___
2
