The correction of skewness of a task performance measure

M.Comm. (Industrial Psychology) / Orientation: In theory, work-based identities have been perceived to predict employee performance at work. The rationale behind this thinking is that individuals apply their identities as they work. Little research is available on the exact nature of the relationship between work-based identity and task performance. Research purpose: The aim of this study is to investigate the relationship between work-based identity and task performance before and after the correction of the negatively skewed task performance measure. Motivation of the study: This study will shed light on how to statistically correct negatively skewed task performance ratings. Currently, limited literature exists on how to correct this skewness with the aim of understanding the work-based identity task performance correlation. Research design: The study utilised a secondary data analysis (SDA) approach within the quantitative research paradigm. This study was performed on a cross-sectional survey (n = 2,429) of data which was collected from middle management level, and management levels that fell beneath this, in a large South African Information and Communication Technologies (ICT) sector company (N = 23,134). Scales used in the study were the Work-based Identity (WI-28) and Task Performance Scales. Results: The results confirm a relationship between work-based identity and task performance before and after the logarithmic transformation of the negatively skewed task performance ratings. The results also indicate that the relationship between workbased identity and task performance remains unchanged after the transformation. Practical/Managerial Implications: Employee behaviours impact general organisational outcomes. Managers should strive to design interventions that draw on employee strengths, such as work-based identity and skills that would lead to improved work experiences. Contribution/Value-Add: The study described in this article builds on the work-based identity literature by showing that this construct can be used to predict task performance. The study also provides evidence of how to statistically correct a negatively skewed task performance measure.
