A group of marketing researchers collected data on the fuel efficiency of vehicles across different engine sizes in terms of the number of cylinders they have (i.e., 4, 6, and 8). The researchers then statistically compared fuel efficiency in terms of miles per gallon (MPG) across these three independent groups. They predicted that four-cylinder cars would demonstrate significantly lower MPG than 6- and 8-cylinder cars.
What is the dependent variable in this scenario?
Fuel efficiency

A group of marketing researchers collected data on the fuel efficiency of vehicles across different engine sizes in terms of the number of cylinders they have (i.e., 4, 6, and 8). The researchers then statistically compared fuel efficiency in terms of miles per gallon (MPG) across these three independent groups. They predicted that four-cylinder cars would demonstrate significantly lower MPG than 6- and 8-cylinder cars.
What type of study design is this?
Between-subjects, non-experiement

Some researchers are interested in understanding how getting into arguments on social media impacts the emotional states of users. They expected to find that those who engage in an online argument will report more anger after the interaction than will those who engage in a social media interaction with no argument. To test this hypothesis, they randomly assigned participants to either have an argument on social media or a normal social media interaction and then measured their levels of anger.
What type of study design is described in this scenario?
Between-subjects experiment

Any study using a factorial design with at least one within-subject component must use which analysis?
Repeated Measures ANOVA

A team of researchers hypothesized that high socio-economic status is positively associated with self-control. To test this hypothesis, they conducted an online survey study with over 750 participants. The researchers collected information on various other traits and participants demographic characteristics as well to report in their write-up.
If this team of researchers wanted to control for participant age in their final analysis, what should they use instead of a bivariate correlation?
Multiple regression

The researchers then statistically compared fuel efficiency in terms of miles per gallon (MPG) across these three independent groups.

What analysis should be used to analyze the data from this study?
One-way ANOVA

A team of researchers were interested in testing the relationship between trait aggression and self-control. However, they read in the literature that both of these variables are also related to trait neuroticism and thus they decide to control for this variable in their analysis. As such, the researchers applied a multiple regression to their data after collecting it. The authors predicted that there would be a negative relationship between trait aggression and self-control after controlling for neuroticism.
How many IVs and levels are described in this scenario?
2 IVs; no levels
