Given the subjectivity of evaluating fit based on benchmarks, it may seem like the chi-square test should be the most objective and useful metric. However, this is not the case. In fact, many consider the chi-square test the least useful metric for model fit. The reason why the chi-sq...
Chi-Square Test of IndependenceThe Chi-Square test of independence is used to determine if there is a significant relationship between two nominal (categorical) variables. First, you can compare the frequency of each category for one nominal variable across the categories of the second nominal ...
This paper presents a simple but efficient Chi-square test for analyzing bike sharing stations usage in mornings and evenings. The proposed method determines stations that keep the same usage patterns over time. Experiments conducted on CitiBike trip data for New York City's bike sharing service,...

Computation ofχ2value. This step evaluates the statistical significance of biases based on thechi-square testagainst the null hypothesis that “occurrence of frequent termgis independent from occurrence of termw”, which we expect to reject. ...
test items, the test instrument, and overall evidence in support of validity claims (Boone et al.2014). Therefore, item fit statistics were examined (Wright1984). Fit statistics indicate how well the empirical data meet the model requirement using a chi-square test (Bond and Fox2007, p. ...
We apply chi-square test to check the frequency of the two groups in each of the four rhythms. We find a significant difference between the two groups of developers in terms of the four work rhythms (p-value < 0.001, Cramer’s V = 0.325). Figure 6 Open in figure viewer...
Simple statistical tools such as descriptive statistics, the chi-square test, and logistic regression have been used to analyze the data. Descriptive statistics are used to understand the nature of the variables extracted for the study. Analysis of Variance (ANOVA) has been used to measure the ...

In addition, the effect of users' relative humidity and air velocity perceptions on the thermal sensation and thermal acceptability were evaluated via cross tabulation and chi-square independence tests. The results show that the difference between the PMV and AMV values is statistically significant and...
