Correlation Matrix. A study was designed to examine the relationship between the TIME (in days) to complete a construction project and a set of variables on the project. Data were collected on 15 projects and included the following independent variables:
SIZE of the contract ($1,000s);
BAD DAYS, number of bad weather days;
STRIKE, a dummy variable whether or not there was a strike 1= strike, 0 = no strike;
SUBCON, the number of sub-contractors involved.
The correlation matrix is given below.
