Table 2. Correlation coefficient for consecutive average event speeds in a colony/treatment (five ants in NC, six in C). (Correlation coefficients are converted into *z*-scores using Fisher’s *r*-to-*z* transformation, which are combined into a weighted *z*_{w} for each treatment that is then compared to assess the significance of the difference between the correlations in the two treatments. The reverse transformation is used to provide a weighted *r*_{w}. See the Data processing and analysis section for more details.)
