Alternative DataSets

Simple linear regression methods may be used to analyze any of the following datasets:

• Diamond Dataset - Diamond Prices

  This dataset contains the prices of diamond rings and the carat size of their diamond stones. The rings are made with gold of 20 carats purity and are each mounted with a single diamond stone. Each observation consists of the following:

  • Size of diamond in carats
  • Price of ring in Singapore dollars

  Consider Price to be the dependent variable and Size the independent variable.

• Fault Dataset - Fault Detection Effectiveness

  This dataset contains measurements of fault detection effectiveness of different test suites for three different programs. The percentage of faults detected by each test suite and the percentage of decisions exercised by each test are recorded. Each observation consists of the following:

  • Fault Detection Effectiveness
  • Decision Coverage
  • Program - CAL, COL, SORT

  Consider "Fault Detection Effectiveness" to be the dependent variable and "Decision Coverage" the independent variable.
