document.write( "Question 1032214: Correlation matrix. Statistical packages can easily calculate correlation coefficents for multiple pairings of variables. Results are often reported in the form of a correlation matrix. Figure 14.18 displays the correlation matrix for data from study of geographic variation in cancer rates.r The variables are:\r

\n" ); document.write( "KID kidney cancer deaths per 100,000
\n" ); document.write( "LEUK leukemia cancer deaths per 100,000\r
\n" ); document.write( "\n" ); document.write( "Notivce that the values for each correlation coefficient appear twice in the matrix, eact tie the variables intersect in either row or column order. For example, the value r = 0.704 occurs for CIG and BLAD and for BLAD and CIG. The correlation of 1 across the diagonal reflects the trivial fact that each variable is perfectly correlated with itself. Review this correlation matrix and interpret results. \r
