We used Fisher's exact or χ tests to asses for differences between proportions in different categories.
34 The χ test was used to assess differences between proportions of offspring obesity in different categories of parental obesity.
Differences between proportions of mature and immature medusae at the beginning and the end of each medusa-season (2010 11: N = 20; 2011–12: N = 26; 2012–13: N = 30) were evaluated using Chi-square 2 × 2 contingency tables, with Haber correction for continuity61.
We used Pearson's chi-squared to test differences between proportions for significance.
For categorical data, we studied differences between proportions with the multiple χ2-test.
Pearson's Chi-square or Fisher exact test was used to assess differences between proportions.
Chi-square analysis was used to compute differences between proportions of 2-week vs. 4-week student responders.
A chi-square test was used to determine statistical significance of differences between proportions of lesions detected by difference MRI sequences.
Inferential analyses for qualitative data were done using chi-squared test for differences between proportions and Fisher's exact test for variables with small expected numbers.
Statistically significant differences between proportions were determined using ?2 tests.
