Chapter 6 Publication
Projects generate a variety of types of publications. These may include
- Pre-analysis plans,
- Final technical reports,
- Public versions of GitHub repositories,
- Public versions of data, and
- Peer-reviewed academic journal articles.
6.1 Pre-analysis Plans
Pre-analysis plans are a tool to promote scientific integrity and transparency. In a pre-analysis plan, we publish our study’s research questions, confirmatory hypotheses, data collection plans, and analysis methods before we begin any analysis of outcomes.
The Lab @ DC uses pre-analysis plans for the following purposes:
- Establish a foundation of transparency and the expectation of public reporting for each randomized evaluation project we undertake.
- Provide a description of the program being evaluated and the context in which it operates.
- Provide a record of the research questions being answered, the outcomes and samples that will be most important in answering them, and the methods we will use to answer those questions.
- Provide a record of what data we have looked at and what we have analyzed at the time the document was published.
- Force ourselves to record known limitations of our analytic approach and how we will or will not address those limitations.
- Allow other people to review, critique, and vet our approach and scientific integrity before or after our results are published.
Importantly, we do not intend for the pre-analysis plan to outline exploratory analyses.
6.3 Publishing Data
We strive to post useful replication data to the extent possible in each project. Some examples of our work doing so include projects on the 911 nurse triage line and 457b enrollment.
The federal OPRE has some helpful advice for doing so here.
6.4 Presenting Results
6.4.1 Estimates and uncertainties
When we want to communicate group estimates along with treatment effects, we display them with barplots or scatterplots. Where we are interested in inference about a treatment effect, we display the control group and treatment group means, with the uncertainty around the treatment group mean representing the uncertainty around the treatment effect. For example,

When we want to communicate treatment effects without both group means being explicit, we do so with a coefficient plot. For example, with the intercept (control group mean),

or without the intercept,

If the project has had multiple senior advisors, include the one who reviewed the document in question.↩︎
