<strong>The</strong>re is no significant <strong>in</strong>teraction between AGE and SEX. Next we add<br />

LIFMOD:<br />

S = 0.1886 R-Sq = 70.3% R-Sq(adj) = 68.3%<br />

<strong>The</strong> p-value for LIFMOD is very highly significant. <strong>The</strong> r-squared value has<br />

jumped by over 20%, show<strong>in</strong>g that the addition <strong>of</strong> LIFMOD has greatly<br />

improved the model. <strong>The</strong> speaker’s degree <strong>of</strong> mental urbanisation is aga<strong>in</strong> a<br />

reliable predictor <strong>of</strong> language ma<strong>in</strong>tenance.<br />

7.5. LIFMOD as a Predictor <strong>of</strong> LEXREC<br />

LEXREC is an <strong>in</strong>dex score achieved by test<strong>in</strong>g the speaker’s knowledge <strong>of</strong><br />

fifty lexical items. As mentioned, this score is regarded with caution, as<br />

passive recognition <strong>of</strong> a word does not imply active daily use. <strong>The</strong> results <strong>of</strong><br />

the analysis, however, show that LEXREC is highly correlated with the other<br />

two l<strong>in</strong>guistic scores, and therefore may be an accurate measurement <strong>of</strong> dialect<br />

use.<br />

LEXREC = 26.7 + 0.353 AGE<br />

S = 6.621 R-Sq = 58.4% R-Sq(adj) = 57.7%<br />

<strong>The</strong> p-value for AGE is highly significant and the r-squared value is quite<br />

high. AGE aga<strong>in</strong> proves to be a reliable predictor <strong>of</strong> dialect use. Next we add<br />

the variable SEX.<br />

LEXREC = 26.7 + 0.353 AGE - 0.11 SEX<br />
