Chapter 1: Introduction to Research in Education
Chapter 1 Learning Outcome Quizzes
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
ST
2. Deviation
3. True information [correct]
4. Randomness
[Feedback for Answer Choice 1]
U
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.
D
[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.
YL
[Feedback for Correct Answer 4]
The signal is what is correct, actual, and true. True information certainly falls into this
category.
AB
[Feedback for Answer Choice 4]
Recall that the noise is composed of factors that drown out, distort, or dilute the signal.
There is always the possibility that the results of a study are simply due to randomness,
which is why study replication is important.
[Q2]
Considering the signal and noise metaphor from Chapter 1, which of the following
represents “noise?”
1. Reality
2. Randomness [correct]
All Chapters Included
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
ST
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.”
U
[Q3]
Which of the following represents the components of an observed finding?
D
1. Signal plus Noise [correct]
2. Signal
YL
3. Noise
4. Either signal or noise
[Feedback for Correct Answer 1]
AB
Observed findings in educational research are always the result of signal and noise.
There are always variables that will be accurate and there will always be distractors. A
good researcher understands how to amplify the signal and drown out the noise.
[Feedback for Answer Choice 2]
Signal refers to what is correct, actual, and true, but this is not all that is included when
collecting data in educational research.
[Feedback for Answer Choice 3]
Noise refers to factors that drown out, distort, or dilute the signal. Therefore, observed
findings certainly do not consist of pure noise.
