Learning Outcome 1.1: Know how the purpose of research, finding the signal, is
influenced by noise that distorts what is reported.
[Q1]
Considering the signal and noise metaphor from Chapter 1, which of the following
represents ―signal?‖
1. Error
2. Deviation
3. True information [correct]
4. Randomness
[Feedback for Answer Choice 1]
Recall that the noise is composed of factors that drown out, distort, or dilute the signal.
Error serves to distract and is therefore considered noise.
[Feedback for Answer Choice 2]
Recall that the noise is composed of factors that drown out, distort, or dilute the signal.
Deviations cause difficulty for researchers and are considered noise.
[Feedback for Correct Answer 4]
The signal is what is correct, actual, and true. True information certainly falls into this
category.
[Feedback for Answer Choice 4]
Recall that the noise is composed of factors that drown out, distort, or dilute the signal.

[Q2]
Considering the signal and noise metaphor from Chapter 1, which of the following
represents ―noise?‖
1. Reality
2. Randomness [correct]
3. Actual relationship
4. Accurate understanding
[Feedback for Answer Choice 1]
Recall that the signal is what is correct, actual, and true. When this definition is
considered, reality would be classified as ―signal‖ and not ―noise.‖
[Feedback for Correct Answer 2]
Recall that ―noise‖ is composed of factors that drown out, distort, or dilute the signal.
Randomness is always a possible reason for the occurrence of a set of data, and
therefore should be considered noise.
[Feedback for Answer Choice 3]
Recall that the signal is what is correct, actual, and true. When this definition is
considered, actual relationships would be classified as ―signal‖ and not ―noise.‖
[Feedback for Answer Choice 4]
Recall that the signal is what is correct, actual, and true. When this definition is
considered, accurate understanding would be classified as ―signal‖ and not ―noise.‖
[Q3]
Which of the following represents the components of an observed finding?
1. Signal plus Noise [correct]
2. Signal
3. Noise
