| | | | | | | |
1. The distance between points on the scale is equal across the range of

| | | | |
In an experimental design, the dependent variable is
| | | | | | |
1. The one that is not manipulated and in which any changes are
| | | | | | | | | | | | |
observed. |
2. The one that is manipulated in order to observe any effects on the
| | | | | | | | | | | | | |
other. |
3. A measure of the extent to which personal values affect research.
| | | | | | | | | | | |
4. An ambiguous concept whose meaning depends on how it is defined.
| | | | | | | | | | |
5. A variable that always systematically varies with the independent
| | | | | | | | | |
variable. - CORRECT ANSWER✔✔-1. The one that is not manipulated
| | | | | | | | | |
and in which any changes are observed.
| | | | | |
A researcher investigated the relationship between test length and
| | | | | | | | |
grades in an Introductory Psychology course. She conducted an
| | | | | | | | |
experiment and found that students taking long exams received better
| | | | | | | | | |
grades than students who took short exams. The independent variable
| | | | | | | | | |
was
1. short exams
| |
2. test grades
| |
, 3. class size
| |
4. gender of student
| | |
5. length of test. - CORRECT ANSWER✔✔-5. length of test.
| | | | | | | | |
What is reduced in a quasi-experiment that an experiment always has?
| | | | | | | | | |
1. Participants.
|
2. Control.
|
3. Confidence.
|
4. Number of observations.
| | |
5. Data. - CORRECT ANSWER✔✔-2. Control.
| | | | |
Internal validity relates to
| | | |
1. How much we can generalise the result to other situations.
| | | | | | | | | |
2. How much we can generalise the result to other samples from the
| | | | | | | | | | | | |
same population.
|
3. How good the data are.
| | | | |
4. How well the data agree with the experimental hypothesis.
| | | | | | | | |
5. How well the features of the experimental design allow us to relate
| | | | | | | | | | | | |
the data to the experimental question. - CORRECT ANSWER✔✔-5. How
