Research methodology guide. An agent skill from revfactory/harness-100.

Research methodology
SKILL.md covers Research Design Types, Sampling Design, Statistical Analysis Method… and Research Ethics, plus 1 more section
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
Experiment design

What it does

Research Methodology is an agent skill from revfactory/harness-100. Research methodology guide. Referenced by the research-designer and statistical-analyst agents when selecting research designs and analysis methods. Use for 'research methodology', 'experiment design', or 'statistical analysis' requests. Actual data collection and IRB review processing are out of scope.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Experimental design and Statistics. The licence is Apache-2.0.

When your agent uses it

Research methodology
Experiment design
Statistical analysis requests

Example prompts

“research methodology”
“experiment design”
“statistical analysis”
“/research-methodology”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Research Methodology loads about 1.1k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 302 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~81
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Enhances the methodology design capabilities of the research-designer and statistical-analyst agents.

Research Design Types

Quantitative Research

Design	Purpose	Variable Control	Causal Inference
Experiment (RCT)	Verify causation	High	Strong
Quasi-experiment	Causation (limited control)	Medium	Medium
Correlational Study	Identify relationships	Low	Weak
Survey	Assess current status	None	None
Longitudinal Study	Change over time	Varies	Medium

Qualitative Research

Design	Purpose	Data Collection
Case Study	Deep contextual understanding	Interviews, observation, documents
Grounded Theory	Theory generation	Interviews, field notes
Phenomenology	Essence of experience	In-depth interviews
Ethnography	Cultural/group understanding	Participant observation

Mixed Methods

Sequential: Quantitative -> Qualitative (explain results)
            Qualitative -> Quantitative (generate hypotheses)
Concurrent: Quantitative + Qualitative (triangulation)

Sampling Design

Sample Size Calculation

Quantitative (mean comparison):
  n = (Z_alpha/2 + Z_beta)^2 x 2*sigma^2 / d^2

  Z_alpha/2 = 1.96 (significance level 0.05)
  Z_beta = 0.84 (power 80%)
  sigma = standard deviation (from prior research)
  d = effect size (minimum meaningful difference)

Survey:
  n = Z^2 x p(1-p) / e^2
  Z = 1.96, p = 0.5 (maximum variance), e = margin of error

  e.g.: 95% confidence, 5% margin -> n = 384 participants

Sampling Methods

Method	Description	Suitable For
Simple Random	Random from population	Small, homogeneous populations
Stratified	Proportional by subgroup	Heterogeneous populations
Cluster	By natural group unit	Region-based surveys
Convenience	Accessible participants	Exploratory research (limited)

Statistical Analysis Method Selection

Analysis Method Decision Tree

Q1: Variable type?
+-- Continuous -> Q2
+-- Categorical -> Q3

Q2: Number of comparison groups?
+-- 1-2 -> t-test (independent/paired)
+-- 3+ -> ANOVA
+-- Relationship analysis -> Regression/Correlation

Q3: Number of variables?
+-- 2 -> Chi-square
+-- 3+ -> Logistic regression

Key Statistical Methods Summary

Method	Purpose	Requirements	Reported Items
t-test	Compare 2 group means	Normality, equal variance	t, df, p, Cohen's d
ANOVA	Compare 3+ group means	Normality, equal variance	F, df, p, partial eta-squared
Chi-square	Categorical variable relationship	Expected frequency >= 5	chi-square, df, p, Cramer's V
Correlation	Relationship between 2 variables	Linearity	r, p
Regression	Prediction/explanation	Linearity, independence	beta, R-squared, p, VIF

Effect Size Guide

Metric	Small	Medium	Large
Cohen's d	0.2	0.5	0.8
r (correlation)	0.1	0.3	0.5
partial eta-squared (ANOVA)	0.01	0.06	0.14
R-squared (regression)	0.02	0.13	0.26

Research Ethics

IRB Considerations

Item	Verification
Informed Consent	Research purpose, procedure, risks, voluntariness
Personal Data	De-identification, retention period, destruction
Vulnerable Populations	Special protections for minors, patients
Conflicts of Interest	Funding source, interest disclosure

Quality Checklist

Item	Criteria
Research Question	PICO or SPIDER structure
Design Fit	Design matches the research question
Sampling	Calculation basis + sampling method
Analysis Method	Suited to data characteristics
Effect Size	Statistical significance + practical meaning
Ethics	IRB approval or exemption justification
