This workshop
focuses on effect size and
statistical power. Statistical
significance testing is often misunderstood and misinterpreted. The workshop will provide a background on
fundamental concepts in Null Hypothesis Significance Testing (NHST)
and then move to a consideration of how the magnitude of effects must
be considered for a complete and accurate interpretation of NHST
results. Alternative measures of effect size and strength of
association will be considered. Practice will be provided in
effect size
calculation and interpretation. The workshop will also define and
discuss statistical power and factors that influence statistical
power. Practice will be provided in how to use software to
estimate power in a variety of research designs and for different
statistical significance tests. Opportunities will be provided
for participants to estimate statistical power and effect size for
their own
research.
