**Learning objectives:**

- THESE ARE NICE TO HAVE BUT NOT ABSOLUTELY NECESSARY
- Describe what a good research question entails
- Discuss research question types
- Explain why research needs a design
- Explain importance of a good research question

## SLIDE 1 {-}

- ADD SLIDES AS SECTIONS (`##`).
- TRY TO KEEP THEM RELATIVELY SLIDE-LIKE; THESE ARE NOTES, NOT THE BOOK ITSELF.
## Research Questions {-}

- Section 1.1, p.3-5
- A question that you plan to answer
- Contributes to improved understanding "how the world works"


1. Well-Defined
2. Answerable
3. Understandable


## Empirical Research {-}
- Section 1.2 p.4-5
- Any research that uses structured observations from the real world to attempt to answer questions.
- Quantitative empirical research uses quantitative measurements (numbers, usually).
- Observations rather than reason
- More data sets, fewer interviews.
- Measurements hard to to collect precisely or interpret accurately
- Numbers we have don’t actually answer the research question we have, what can we do?
- Goal is to collect the right data to answer the question and design reasearch to do this


## Why Research needs a design {-}

- Section 1.3 p.5-7 ,
- Capable of answering the question it's trying to answer
- Needed to evaluate first pass analysis and what to do instead
- Nutrition Research as example of lack of design
1. Not having research capable to answer question
2. Not actually answering the question
- Leads to inconsistent results which people cannot rely on nor use
- Could lead to too difficult a question to answer, but its still a takeway

## Book Goals {-}

To Improve Confidence in crafting a research project, what kind of data needed, and calculations to perform on data

-First Half:
1. Ways to build an answerable research question
2. Think of quantitative empirical research to perform to answer question

-Second Half:
1. "Toolbox" using observational data
2. Tools are widely applicable to answer many questions

## Discussion/Practicals {-}
Questions, Discussions, or Examples to fill in during Book Club Meeting

**Learning objectives:**

- THESE ARE NICE TO HAVE BUT NOT ABSOLUTELY NECESSARY
- Define what a Research Question is
- Compare Data Mining and Research Questions
- Determine if a question is good

## SLIDE 1 {-}
## What is a Research Question? {-}

- ADD SLIDES AS SECTIONS (`##`).
- TRY TO KEEP THEM RELATIVELY SLIDE-LIKE; THESE ARE NOTES, NOT THE BOOK ITSELF.
- Section 2.1 p. 9-12, Section 2.3 p. 15-16
- When answered, will improve understanding of how the world works.
- There exists data when found results in believable answer
- Can be Answerable with evidence: Avoid ambiguous questions such as "best"
- It should inform theory: answer something broader than itself

- Theory
- Tells us why
- May be True or False - but explains why we might see outcomes

- Good Question takes us from Theory to Hypothesis
- When answered improves ability to explain why
- If this is how the world works, what should I expect to observe?
- Gives us something new about why

- Theory -> Research Question or Research Question -> Theory

- Right data for right questions

- Two Checks for Condition for Research Question:
1. Could we answer the question?
2. Does the question tell us about how the world works?

- Checks if Research Question Informs Theory:
1. Would unexpected result change your understanding of the world?
2. If unexpected result doesn't change understanding, then bad question
3. If answered, hard to explain away if inconvenient

## Data Mining vs. Research Q's {-}
- Section 2.2 p.13 - 16
- Data Mining is good at finding patterns and making predictions under stability
- Not good at improving understanding nor improve theory main reason are:
1. Answers what's in the data , not explaining why. Correlation != Causation
2. Does not deal with abstraction, can see observations but not at developing theory
3. Results in false positives - observations found in sample but not outside of it. Random relationships eventually occur when testing everything

- Can lead to Research Questions
- Come to data without a theory, noticed interesting data patterns
- Confirm it holds up in other data aka replication of data patterns


## Considerations for a good Research Q {-}
- Section 2.3 p. 15-16, Section 2.4 p. 16-18
- Sources of Questions:
- Curiosity
- Theory
- If this is what I expect the world to work, what would I expect to see in the world?
- Opportunity
- What questions would this data allow me to answer?

- Research Questions tells us why hypothesis to test

1. Potential Results
- If you cant say something interesting from results, Question and Theory not closely linked
2. Feasibility
- Possible vs. Realistically Obtainable Data
3. Scale
- Consider time, resource constraints
4. Design
- Finding a reasonable research design that can answer it
5. Simplicity
- Don't combine multiple determinants into the question to answer
