Logistic regression was used to analyze data for differences between 2008 and 2012 survey responses, after adjustment for correlations among the measurements in each of 6 child care categories sampled.A significantly larger percentage of sites in 2012 than in 2008 always served water at the table with meals or snacks (47.0% vs 28.0%, P =.001).
Team members will use a variety of statistical methods to gather and analyze data, including regression discontinuity models, difference-in-difference models, sibling and twin pairs, various fixed effect strategies and best practices for designing randomized-control survey experiments.
However, during the internal reviews we frequently encountered a question "how can the dispersion analysis and probability intervals help biologist to analyze data and to detect significant differences in gene expression" (see also comment of the third referee).
The frequency of the G/G genotype in patients was 20 (4.8%) and in controls was 102 (24.5%) (Table 2), where statistically analyzed data indicated a significant difference between the two groups (P < 0.0001) (OR = 4.021, 95% CI = 2.21 7.29, P < 0.0001).
A Student's t test was used to asses the sex difference in analyzed data within the same animal group.
For all studies, one-way ANOVA was used to test for significant (p-value of <0.05) differences in the analyzed data.
The differences between 2 analyzed data were compared using the χ test and Student's t-test.
This test is applied to raw values, and the post-test of the Friedman test indicates whether there is any statistical difference between each analyzed data set; to identify which data set has the best values, boxplot charts are used.
In order to analyze these differences, data collected from Monte Carlo experiments of irregular arrays with 16, 25, 36, 49 and 64 microphones are compared.
In order to analyze these differences, data were collected for percentage of revenue from local and county sources, student-teacher ratios, and per-student expenditures for 108 school districts in western Oklahoma over 19 years, from 1997 to 2105.
