Results
Summarizes data collected and the statistical treatment used
report data in sufficient detail to justify conclusions
mention all relevant results, including those that run counter to the
hypothesis
no raw data unless used one or a few subjects
don’t discuss implications of results
tables and figures are included here
Statistical presentation
when reporting inferential statistics (e.g., t tests, F tests and chi-square),
include information such as:
the obtained magnitude or value of the test statistic
degrees of freedom
probability of obtaining a value as extreme (or more) than the one
obtained
direction of effect
include descriptive statistics (e.g., per-cell sample size, means,
correlations, standard deviations) so nature of effect can be understood
recommends use of confidence intervals, generally one (e.g., a 95% or
99%) throughout course of paper
Informationally adequate statistics
1. For parametric tests of location (generally) use cell means, cell
sample sizes, and a measure of variability.
2. For randomized-block layouts, repeated measures designs, and
multivariate analyses of variance, vectors of cell means and cell
sample sizes, along with the pooled within-cell variance-covariance
matrix
3. For correlational analyses, sample size and variance-covariance (or
correlation) matrix, with other information specific to procedure
4. For nonparametric analyses, various summaries of raw data
Statistical power (likelihood of correctly of rejecting the tested
hypotheses, given a particular alpha level, effect size, and sample size.)
Provide evidence that your study has sufficient power to detect effects of
substantive interest
Statistical significance, in general recommends reporting the exact
probability (p value).
Effect size and strength of relationship, should include some index of
effect size or strength of relationship which can be estimated with a
number of common effect size estimates. General rule is to provide reader
with enough information to access the magnitude of the observed effect or
relationship
