Description
### Overview
Create a tutorial that introduces undergraduate students to the scientific process as a structured method for asking questions, testing claims, analyzing evidence, and refining conclusions. The tutorial should explain the scientific process as an iterative workflow rather than a rigid checklist.
### Action Items
Research and document the major stages of the scientific process, with clear undergraduate-friendly explanations for each stage.
Identify the core concepts students should understand, including:
Observation
Research question
Hypothesis
Prediction
Experiment or study design
Data collection
Analysis
Interpretation
Replication
Peer review
Limits of inference
The tutorial should cover the following core steps:
1. **Observation**
* Explain how scientific work often begins with noticing a pattern, problem, gap, contradiction, or unexplained phenomenon.
* Include examples from everyday life, civic data, public health, environmental science, or social science.
2. **Background Research**
* Explain why researchers review existing knowledge before designing a study.
* Include how background research helps clarify definitions, avoid duplicate work, identify prior findings, and reveal open questions.
3. **Research Question**
* Explain how to turn a broad curiosity into a focused, answerable question.
* Include examples of weak versus strong research questions.
4. **Hypothesis**
* Define a hypothesis as a testable explanation or proposed relationship, not simply a guess.
* Explain the difference between a hypothesis, prediction, theory, and opinion.
5. **Prediction**
* Explain how predictions describe what we expect to observe if the hypothesis is correct.
* Use “If the hypothesis is true, then we should observe…” as a suggested format.
6. **Study or Experiment Design**
* Explain how researchers decide what data is needed, what variables matter, and what comparison will be made.
* Include key concepts such as independent variables, dependent variables, controls, confounding variables, sample size, and measurement quality.
7. **Data Collection**
* Explain how evidence is gathered through experiments, surveys, observations, public datasets, sensors, interviews, or simulations.
* Emphasize documentation, consistency, and data quality.
8. **Analysis**
* Explain how researchers use statistics, visualization, and logical reasoning to evaluate evidence.
* Include the idea that analysis should connect directly back to the original research question and hypothesis.
9. **Interpretation**
* Explain how researchers decide what the results mean and what they do not mean.
* Emphasize uncertainty, limitations, alternative explanations, and the difference between correlation and causation.
10. **Conclusion**
* Explain how conclusions summarize what was learned, whether the evidence supports the hypothesis, and what questions remain.
* Clarify that unsupported hypotheses are still scientifically valuable.
11. **Communication**
* Explain the importance of sharing methods, evidence, results, limitations, and conclusions clearly.
* Include common formats such as reports, papers, presentations, dashboards, notebooks, and posters.
12. **Replication and Revision**
* Explain that scientific knowledge improves when studies are repeated, challenged, refined, or expanded.
* Present the scientific process as a cycle: results often lead to better questions, improved methods, and new hypotheses.
Create a simple visual or written flow of the process:
Observation → Background Research → Research Question → Hypothesis → Prediction → Study Design → Data Collection → Analysis → Interpretation → Conclusion → Communication → Replication / Revision
Also include a short applied example that walks through the full process from beginning to end. A recommended example is:
* Observation: Some neighborhoods appear to have slower 311 response times.
* Background Research: Review how 311 requests are categorized and how response time is measured.
* Research Question: Do 311 response times differ by neighborhood or council district?
* Hypothesis: Some districts have longer median response times than others.
* Prediction: If the hypothesis is correct, median response time will vary meaningfully across districts.
* Study Design: Compare similar request types across districts over the same time period.
* Data Collection: Use a sample of 311 service request records.
* Analysis: Calculate median response time by district and request type.
* Interpretation: Differences may exist, but request type, reporting volume, staffing, and seasonality may also explain the pattern.
* Conclusion: The data may suggest unequal response times, but further analysis is needed before making a causal claim.
* Communication: Present findings in a short report, chart, or dashboard.
* Revision: Refine the question by controlling for request type, urgency, or time of year.
Document common misconceptions to avoid:
* A hypothesis is not just a random guess.
* One study rarely proves something permanently.
* Correlation does not automatically mean causation.
* A null or unexpected result is not a failed study.
* Science is not always linear.
* Data does not interpret itself.
* Good conclusions must acknowledge uncertainty and limitations.
It should be written for undergraduate students with little or no prior research experience.

The tutorial should present the scientific process as an evidence-based reasoning cycle. It should be practical, clear, and connected to real research tasks students may encounter in data science, civic technology, social science, public policy, or laboratory science.
* If this issue requires access to 311 data, please answer the following questions:
* Do you need a one-time or ongoing dump of the data?
* A one-time sample is sufficient.
* Do you need a subset of data or the entire data set?
* A subset is recommended. The full dataset is not needed.
* If a subset is needed, please define subset characteristics.
* Use a limited date range, such as 6–12 months, with fields for request type, open date, close date, status, location, neighborhood or council district, and request category.
* Do you need online access via an API or a download of data?
* A CSV download is preferred for tutorial purposes. API access is optional if the tutorial includes a live data retrieval section.
