The combination ofdata.frame()andtable()in R provides a powerful method for counting the occurrences of unique values in a dataset. By converting the output oftable()into a data frame, you obtain a structured summary that includes the unique values and their respective frequencies. This approach...
(2010) noted elevated frequencies of micronuclei and nuclear abnormalities in Oreochromis niloticus exposed to polluted water under laboratory conditions. Similar results were observed in the case of fish of the same species exposed to refinery effluent (da Silva Souza and Fontanetti, 2006; Hoshina ...

in which the groups were allowed to have different population frequencies for alleles and genotypes but were assumed to have a common effect. Heterogeneity was tested by comparing the null hypothesis of the effect being the same in all populations to the alternative hypothesis of each population hav...
Frequencies were compared using the Fisher’s exact test for two groups and the Chi-square test for three goups. A p-value < 0.05 was considered statistically significant. The statistical analysis was performed with Analyse-it on Microsoft Excel version 2108 (Build 14326.20404) with the ...
Clinical improvement of the olfactory threshold score was independent of the group χ2(1) = 0.04, p = 0.83, but clinical improvement in identification was more frequent in subjects with olfactory loss, χ2(1) = 5.3, p = 0.02. Frequencies of clinical improvement across the...
