1Referring to the correlation between two sets measurements, one of which is dichotomous.
‘In addition, point biserial correlations between items reflecting patient concerns and demographic measures were analyzed.’
‘The point biserial correlation allows the researcher to correlate continuous and dichotomous data.’
‘In a similar way, the short-cut equations for the point biserial and phi coefficients are also special cases of the Pearson.’
‘Spearman rho correlation coefficient, point biserial correlation, and multiple correlation were used to describe associations between variables.’
‘To test whether or not altruists and non-altruists express different nonverbal behaviours during a self-presentation, point biserial correlation coefficients were calculated.’
1.1Zoology Botany Arranged in or consisting of two series or rows.
‘Another biserial morphotype with a coiled pattern is produced by relatively narrow ranges of all parameters and resembles simple spiral morphotypes with two series of chambers.’
‘For instance, they cannot model gradual or abrupt changes of growth modes that cause different chamber arrangements during ontogeny, such as planispiral and switching to biserial or streptospiral to uniserial.’
‘As in non - stelleroid echinoderms, asteroid ambulacrals form a biserial column.’
‘Some rhipidocystids have standard biserial brachioles whereas others have uniserial brachioles.’
‘Uniserial budding produces a chain (runner or branch) one zooid wide, whereas, colonies that are biserial, zooids share one wall and result in a strip two zooids wide.’
