Unlike Pearson&#8217;s correlation, which requires interval or ratio data and assumes linear relationships, Spearman&#8217;s correlation can handle non-linear monotonic relationships and is robust to outliers. This makes it ideal for ordinal variables, where data are ranked but not measured on a continuous <a href=\"https:\/\/researchmethods.imem.nl\/wp\/2024\/11\/20\/brand-luxury-scale\/\">scale<\/a> (Scribbr, n.d.). When reporting Spearman&#8217;s correlation in APA style, it is important to italicize the symbol $$ r_s $$ and report the value to two decimal places (Purdue OWL, n.d.). Additionally, the significance level should be clearly stated to inform readers of the statistical reliability of the findings (APA Style, n.d.).<\/p>\n\n\n\n<p><strong>References<\/strong><\/p>\n\n\n\n<p>APA Style.
