The purpose of this workshop is to increase awareness among management
researchers of the severe limitations of Null Hypothesis Significance
Testing (NHST) and to introduce alternative approaches based on effect size
measures and confidence intervals.
NHST has been criticized by methodologists on various grounds (Cohen, 1994;
Cortina & Folger, 1998; Schmidt, 1996; Starbuck, 2006; Thompson, 1996).
Their criticism suggests that the extensive use of NHST in quantitative
management research has led to the accumulation of deceptive findings in
the management literature. In a field that aspires to provide useful
advice to managers, researchers need to focus on practically important
effects that are robust across a wide variety of settings. To identify
practically meaningful findings, methodologists have recommended the
reporting of effect sizes and confidence intervals as an alternative to
NHST. Recently, approaches for estimating confidence intervals for effect
size measures have also been introduced (Cummings & Finch, 2001; Kline,
2004). The application of alternatives to NHST by management researchers,
however, has been limited by both a lack of sensitivity regarding the
inherent problems of NHST and a limited familiarity with alternative
approaches. Our two-hour workshop addresses these issues in the following
three modules:
• Critique of NHST (2 speakers)
• Alternatives to NHST (1 speakers)
• Round-table discussion for hands-on advice
No pre-registration is required to attend this session.
