The Pearson rank-order correlation test showed a significant negative correlation between PLR and birth weight (r=-0.189, p=0.001) as well as gestational age (r=-0.345, p=0.001) among the studied PTBs (Figure 2).
The first research question asks "What is the relationship between intrapersonal identity conflict and social support systems for the Saudi students in the United States?" This question was addressed using the Spearman's rank-order correlation test between identity conflict and the social support scores.

To compute the Spearman rank-order correlation coefficient the initial assessment data and the second assessment data were separately ranked.
The Spearman's rank-order correlation was performed on the results from the quantitative data collected from the random sample (Zikmund, 1994).
We assessed the stability of risk-taking and impulsive behaviors using one way analyses of variance (ANOVA), Pearson correlations, Spearman rank-order correlations, and intraclass correlation (ICC) analyses.
To test this hypothesis, we rank ordered the mean ratings on eroticism and romanticism for the 17 sexual activities separately for male participants and female participants, and then computed a Spearman rank-order correlation between the ranks for eroticism and romanticism.
For finding the most important parameter among the four, we calculated the spearman rank-order correlation coefficient (rs) between each of the four rank lists IR, OR, RR, and PR, and the TU rank list.
To assess agreement between male and female participants in their self-ratings of enjoyment using the correlation method, we rank-ordered the mean self-ratings of each sex and conducted a Spearman rank-order correlation between the two sets of ranks.
The correlation between the average number of embryos per capsule and the ranking of sites in terms of wave exposure was determined using a Spearman rank-order correlation analysis, with all sites within an exposure category being given the same rank; this analysis revealed no significant correlation for the seven populations (Spearman rank-order correlation: [r.sub.s] = -0.077, n = 7, P = 0.869) or more broadly among the nine populations ([r.sub.s] = -0.581, n = 9, P = 0.101).
Using the hierarchy of preferred stimuli for each assessment, a Spearman's rank-order correlation was calculated to determine the level of correspondence between item rankings in each assessment.
In 11 studies performed by the authors, the rank-order correlation between both techniques was 0.93.
We observed a significant positive correlation between the concentration of the SRY gene and gestational age (Spearman rank-order correlation, r = 0.22; P = 0.04).
Furthermore, not much is known about how properties of significance tests of correlation, based on the Student t test and on the Fisher r to Z transformation, extend to the Spearman rank-order correlation method.
A rank-order correlation analysis demonstrated that a plan's relative performance on a particular measure with respect to other plans tended to be fairly stable across 1996, 1997, and 1998 reporting years.
