“…Observations were recorded using the aforementioned techniques and tested for agreement at each second during the observation period. The CORR procedure of SAS version 9.3 (SAS Institute, Cary, NC) generated Pearson correlation coefficients among all observers, and all correlations throughout the study were classified according to criteria used by Bikker et al (2014): negligible, 0.00 to 0.30; slight, 0.31 to 0.50; minor, 0.51 to 0.70; moderate, 0.71 to 0.90; and strong, 0.91 to 1.00. A chi-squared test was performed using R version 3.1.0 (R Foundation for Statistical Computing, Vienna, Austria) to evaluate observer agreement on behaviors performed at each second.…”
