What makes science…good science?
Replication & Reproducibility
Replication: The process of applying the same methodology with a different sample and research group
Reproduction: Taking all materials from a study and coming to the same conclusions
Replication & Reproducibility 🍰
I want to bake a cake!
- Find a recipe online (try ignoring their life story narrative)
- Get ingredients (Wegmans if you 💰)

Replication & Reproducibility 🍰
I want to bake a cake!
Reproduction
- Find a recipe online –> Find their kitchen
- Get ingredients –> Use their ingredients
- Follow recipe and bake –> Watch what they do and follow
- Enjoy the delicious cake –> Enjoy cake (and jail for B&E)
Replication & Reproducibility 📊
| Replication | Reproducibility |
|---|---|
| Have a similar research question | Use the same research question |
| Collect your own data | Use their data |
| Follow their steps with your resources | Follow their steps with their resources |
| Outcome: Similar results (depends on other factors) | Outcome: Identical results |
Replication & Reproducibility 📊
Goals of Science
Important: We want to replicate other researchers work
MOST Important: Be able to reproduce all of our results
You are your own worst collaborator!
Does this play out in the field??

What can we do about it? 🤷
Installing and Using R
Break Time ☕
Or at least I hope it is around this time
Now back to the show!
Working with R-Studio
R-Studio is just like a kitchen 🧑🍳
The Environment pane is the pantry/fridge
The Console is like the oven/stove
The Markdown document is the recipe
The bottom right sometimes acts as the little window on the oven where you can see things baking
Creating a Project puts these things in their place
Next Steps
Create a project
Set up a Markdown Document
Run and Knit the document
Live Example
In Class Workshop
Create a new .Rmd file and name it introduction.Rmd
In the markdown, delete everything that is unnecessary
Introduce yourself in the text portion of the document
Load tidyverse and use the starwars dataset
