- For the following research scenarios, state the most appropriate statistical method that could be used to answer each question. Please carefully consider the nature of the variables given when determining which test to use.
If you feel that there is not enough information provided (including ambiguous coding or definition for a given variable) and additional information would indicate the use of a particular test, please state the assumption you are making so it may be considered. Note that more than one test could be appropriate; however, you only need to select one!
You may still choose “I don’t know” as an option but be sure to tell me why if that’s the case.
- Jedi Master Yoda recommended that Force-sensitive individuals above a certain age threshold should not be trained as Jedi. However, we know that some Jedi (e.g., Anakin Skywalker) began their Jedi training at older ages. Is age when training began (in years) associated with whether or not a Jedi turns to the Dark Side?
- Older Jedi Padawans (i.e., trainees) often have personal attachments that might contribute to turning to the Dark Side. Is having personal attachments (yes / no) associated with whether or not a Jedi turns to the Dark Side?
- Midi-chlorian counts are linked to sensitivity to The Force and may confer extraordinary abilities. You are curious about the mean midi-chlorian count of Wookiees, Gungans, and Ewoks. How could you test whether midi-chlorian count differs between these three species?
- Jedi Master Mace Windu raised a concern that Jedi may not be ambidextrous (i.e., able to use both their right and left hands equally well) with respect to their lightsaber skills. How could he test this hypothesis?
- Does the average intergalactic smuggler make the Kessel Run in 12 parsecs?
- Among starships with hyperdrives (i.e., the equipment that allows a ship to travel at the speed of light), is there a relationship between the eco-friendliness of the ship (terrible, mediocre, good, or fantastic) and the average number of times per month the hyperdrive is used? Note that we are only considering starships with hyperdrives here and there is no comparison group without hyperdrives to consider.
- After controlling for a variety of variables, does the number of sandstorms per year predicts the average annual temperature on the desert planet of Tatooine?
- Are children with a family history of Jedi training more likely to become Jedi themselves?
- Is the average luminescent blade of a lightsaber actually 3 feet long?
- Is political loyalty (Rebel / Empire) associated with what type of Starship (X-wing / TIE fighter / Imperial Star Destroyer / Rebel Transport) an individual prefers?
