Exam 8: Experimental Design II: Factorial Designs

In a 2x3 mixed factorial design, with 10 people needed to fill the upper left hand cell of the matrix, how many people will be needed to complete the experiment?

In a 2x2 design, the following results occur: Which of the following is true?

A researcher discovers that extroverts solve problems better than introverts when in a large room, but that introverts do better than extroverts in a small room. Which of the following is true?

Which of the chapter's research examples used a P x E mixed design?

The next questions refer to the following experiment: A researcher investigated the effect of a child's attractiveness and gender on judgments of personality and intelligence. Male teachers were shown photos of children to obtain their "first impressions" of children. Each teacher was shown four photos (the order was randomized for each teacher): an attractive boy, an unattractive boy, an attractive girl, and an unattractive girl. The teachers rated the apparent friendliness of the child and also estimated the child's intelligence. -Which of the following is true about the study?

The next questions refer to the following experiment: A researcher studied the influence of crowding (low, medium, and high crowding) on reading comprehension between two types of third graders. Half the children randomly assigned to each crowding condition were classified as “good” and half “poor” on an assessment of verbal fluency. In the study, each child read a 750-word passage and was tested on it later. -Which of the following is true?

Any experimental design that includes more than one independent variable is called a(n) ________ design.

An experimenter fails to find a difference between two groups of subjects on a problem solving task because both groups solve virtually all the problems; the study has produced a(n) _________ effect.

A study by Shute compared students who scored high or low on a measure of their tendency to be "exploratory." Half of each group then learned about electricity through a "rule-application" strategy, while the other half learned through a "rule-induction" strategy. Which of the following was true?

What is the basic difference between a mixed factorial design and a PxE factorial design?

A 2x4 factorial design has

The next questions refer to the following experiment: A researcher studied the influence of crowding (low, medium, and high crowding) on reading comprehension between two types of third graders. Half the children randomly assigned to each crowding condition were classified as “good” and half “poor” on an assessment of verbal fluency. In the study, each child read a 750-word passage and was tested on it later. -Twenty poor comprehenders are tested in the low crowding condition. To keep the same N in all the cells, how many children will participate in the experiment?

An ATI design would be considered an example of which of the following?

In a 2x2 design, the following results occur: Which of the following is true?

In a 2x2 design, the following results occur: Which of the following is true?

Jenkins and Dallenbach did a famous study on the phenomenon of retroactive interference in the 1920s, in which they found that getting a good sleep before an exam might not be a bad idea. Which of the following was true about their study?

A factorial design using both a manipulated and a subject variable is referred to as a(n) ______ design.

A 2x3 factorial design has six

In a 2x2 design, the following results occur: Which of the following is true?

The next questions refer to the following experiment: A researcher simultaneously investigated learning style and teaching style. Students were identified as either visual/concrete learners or verbal/abstract learners, on the basis of a learning style survey. For each type of student, half were taught a statistics lesson using a computer program that included a lot of graphics, while the other half used a computer program with fewer graphics and more verbal material. After working through the program, all students were given a test on statistics. -How would you describe the design of this study?
