Exam 14: Glm 3: Factorial Designs

Using the data in the table below, what would be the psychological interpretation of the analysis?

Which of the following is a key feature of factorial ANOVA?

If a study has employed a two-way mixed ANOVA, what does this mean?

The histogram shown below relates to a study undertaken by Baker et al. (2003) of the impact of roster changes on absenteeism and incident frequency in an Australian coal mine. The average monthly absenteeism rates in the three specific work areas examined, according to collection period. The authors state that 'there was a trend for increased rates during the second (3.11%) and third (3.72%) collection periods within the CPP sector, compared to the first (1.87%), F(2,24) = 2.441, p > 0.05.'

Using the data in the table below, what value should appear where there is a Y?

A study undertaken by an unknown author in 2000 investigated 'factors influencing sense of personal control among elderly rural women' (source: http:/ / bama.ua.edu/ ~jleeper/ 627/ project1.doc). What does the interaction in the graph show in terms of personal control and health status? Source: http:/ / bama.ua.edu/ ~jleeper/ 627/ project1.doc

Which of the following is not an example of factorial ANOVA design?

How many dependent variables does a two-way ANOVA have?

When cell means for subgroups are examined, what is being investigated?

In a factorial design with two factors, if the effect of one factor appears to depend on the levels of the second factor, this is called

An experiment was done to look at the positive arousing effects of imagery on different people. A sample of statistics lecturers was compared against a group of students. Both groups received presentations of positive images (e.g., cats and bunnies), neutral images (e.g., duvets and light bulbs), and negative images (e.g., corpses and vivisection photographs). Positive arousal was measured physiologically (high values indicate positive arousal) both before and after each batch of images. The order in which participants saw the batches of positive, neutral and negative images was randomized to avoid order effects. It was hypothesized that positive images would increase positive arousal, negative images would reduce positive arousal and neutral images would have no effect. Differences between the subject groups (lecturers and students) were not expected. What technique should be used to analyse these data?

What is shown in the following graph?

Which of the following is not a question answered by two-way ANOVAs?

An experiment was performed in which participants were given lists to learn in either quiet or noisy environments. On later recall either congruous or non-congruous cues for recall were given and recall was either in the same or different context of learning. What design is this experiment?

Factorial ANOVA for the maintenance sector is reported as F(2.24) = 19.186, p < 0.05. What does this indicate?
