•Nominalmeasurements classify information and count the frequency of observations within each class. An example is tabulation of the numbers of protons and neutrons in an atom. •Ordinalmeasurements specify order, or relative position. Ordinal scales may be objectively determined (e.g., thek,l,...

. Here we show that a universal microbial decomposer network assembles despite location, climate and seasonal effects, with evidence of increased metabolic efficiencies to process the ephemeral and abundant lipid- and protein-rich compounds. Key members of the microbial decomposer network are also found...
In such cases, a simple bar chart could be used to illustrate the difference in mean scores between the categories of a nominal or ordinal variable. For example, a simple bar chart could be used to illustrate the differences in the dependent variable, income, based on the three categories ...
Latent profile analysis was used to identify subgroups of articles within sample 1 based on a set of nominal, continuous and ordinal method variables (e.g., study design, sampling technique, sample size, assessment of DC, statistical analyses). Most variables introduced in the previous chapter we...
A clustered bar chart can be used when you have either: (a) two nominal or ordinal variables and want to illustrate the differences in the categories of these two variables based on some statistic (e.g., a count/frequency, percentage, mean, median, etc.); or (b) one continuous or ...
For example, place of birth is a nominal categorical variable. Conversely, answers in the Likert scale to the question: 'Do you agree with this statement: A child's education is the responsability of parents, not the school system.', compose an ordinal categorical variable in which the ...
Comparisons between groups were performed by Mann–Whitney U test or Kruskal–Wallis test, where one of the variables or the outcome was a nominal value, and the Chi square test when both the variable and outcome were nominal values. Where both the variable and outcome were ordinal values, ...
For ordinal or binary round-robin variables, the latent-response assumption could be applied during Stage 1 estimation of SRM summary statistics by incorporating a threshold model, similar to item factor analysis [94]. The summary statistics analyzed in Stage 2 would then be polychoric correlations...
