Comparing methods for measuring the size of oysters
A data frame with 30 observations on the following 5 variables.
ID
ID number of each oyster
Weight
Weight (in grams)
Volume
Volume (in cubic centimeters)
ThreeD
Measurement from a 3D system (pixels)
TwoD
Measurement from a 2D cross-section (pixels)
In 2001 engineers at an R&D lab Agri-Tech, Inc, in Woodstock, Virginia, designed a 3-D system that they hoped would improve on the existing 2-D system for measuring the size of oysters. The 3-D system used computer scanning to estimate an oyster volume, whereas the old 2-D system estimated a cross-sectional area. Data shows the result of both systems, as well as the actual weight and volume of each oyster used in calibration.
