233. Dr. RNS conducted a ______________ factorial design to examine the effects of music and room temperature on participant's memory. Participants were randomly assigned to study a list of nonsense words either listening or not listening to music in either a warm or cold room.

  1. 1 x 2
  2. 2 x 4
  3. 2 x 2
  4. 4 x 4
Correct answer: (B)
2 x 2

234. In factorial designs, the response produced when the treatments of one factor interact with the treatments of another in influencing the response variable is known as

  1. the main effect
  2. interaction
  3. replication
  4. none of these
Correct answer: (B)
interaction

235. What is the Variation due to Cache?

  1. 84%
  2. 76%

236. A three-way interaction is said to occur when:

  1. All three possible two-way interactions, plus main effects of all three factors, are present in the data
  2. There are simple main effects of each factor at every level of either of the other two factors
  3. The simple interactions between two factors are not homogeneous across all levels of the third factor
  4. All three possible two-way interactions are present in the data
Correct answer: (C)
The simple interactions between two factors are not homogeneous across all levels of the third factor

237. What is the value at the position of (V)?

  1. 0.85

  1. the square root of the variance of the error term
  2. an estimate of the square root of the variance of the error term
  3. the square root of the variance of the dependent variable
  4. the square root of the variance of the predictions of the dependent variable
Correct answer: (D)
the square root of the variance of the predictions of the dependent variable

239. What is the purpose of a multiple regression?

  1. To predict scores on a dependent variable from scores on a single independent variable
  2. To predict scores on an independent variable from scores on a single dependent variable
  3. To predict scores on an independent variable from scores on multiple dependent variables
  4. To predict scores on a dependent variable from scores on multiple independent variables
Correct answer: (C)
To predict scores on a dependent variable from scores on multiple independent variables
