- Previously in class, you conducted an experiment to gauge how a
stimulus affected people’s perception of time.
- Some people were given a treatment, others were not.

- In this lab, we’ll use the data cycle to analyze the
*research question*:

*Does the stimulus your class chose change people’s perception of
time?*

**Write down two statistical investigative questions that will help you answer the***research question*from the previous slide.- Then,
*export*,*upload*,*import*your experiment data into RStudio.- If you’re having trouble coming up with good statistical investigative questions, try loading the data and looking at the variables.
- Ask yourself,
*How would I use these variables to answer the research question?*

- Create appropriate plots to answer your statistical investigative questions.
**Are there any outliers or unusual observations that require some cleaning before you can interpret your plots?**- Calculate appropriate numerical summaries to answer your statistical investigative questions.
**Write down a few sentences interpreting your plots and summaries.**

- Is it possible your initial results occurred by chance alone?
- Use repeated shuffling to determine how likely the typical difference between the two groups occurred by chance alone.
**Create a plot and use it to justify your answer.**

- What do you conclude about the
*research question*?**Write a report using the plots and analysis you conducted to answer the***research question*.- Be sure to describe how you conducted your experiment.
