Lab 3A: The Results Are In!
Lab 3A - The results are in!
Directions: Follow along with the slides, completing the questions in blue on your computer, and answering the questions in red in your journal.
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?
Coming up with questions
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?
Analyzing our data
Create appropriate plots to answer your statistical investigative questions.
Calculate appropriate numerical summaries to answer your statistical investigative questions.
Write down a few sentences interpreting your plots and summaries.
Wrapping it up
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.
