If your research question follows up on previous research, your decision about what to observe may be determined by . |
|
|
2 | |
If repeated measurements made under identical conditions give the same result, the measure is said to be . |
|
|
3 | |
The precision of an estimate of a population mean from a sample is known as . |
|
|
4 | |
The degree of agreement among several observers of the same measure provides a measure of reliability. |
|
|
5 | |
When assessing the reliability of a measure, one can administer the measure twice and then correlate the two sets of scores. The measure is reliable when the correlation is . |
|
|
6 | |
is assessed by combining two forms of the same measure in a single test. |
|
|
7 | |
A measure that is produces results that agree with a known standard. |
|
|
8 | |
If a measure lacks then it fails to measure what it was intended to measure. |
|
|
9 | |
If a test adequately samples behavior it is said to have validity. |
|
|
10 | |
If the scores on a new measure correlate highly with scores on another established measure administered at about the same time, the new measure has validity. |
|
|
11 | |
Phrenology failed as a science because as measures of temperament and ability, the phrenologists’ measures were . |
|
|
12 | |
Dividing one value by another gives meaningful results only if the value has been measured on a(n) scale. |
|
|
13 | |
Values measured on a(n) scale can be rank-ordered, but the distance between values is not known. |
|
|
14 | |
A measure is said to be valid if it reflects what people must do in real-life situations. |
|
|
15 | |
If your measurements in various conditions of an experiment remain at or near the top of the scale, variability in scores is restricted by this effect. |
|
|
16 | |
A count of the number of behavioral responses over time gives the of responding. |
|
|
17 | |
In the verbal report, participants speculate on how they would react in a certain future situation. |
|
|
18 | |
When designing experiments, one must take into account the nature of human participants. |
|
|
19 | |
Demand characteristics of an experiment that signal what attitude is needed in order to conform to the role of research participant are called cues. |
|
|
20 | |
effects emerge when the experimenter has preconceived ideas about the capacities of the participants. |
|
|
21 | |
If neither the participant nor the person conducting the experiment knows which treatment condition the participant is in, a(n) technique is being used. |
|
|
22 | |
You can increase the accuracy and reliability of your measurements, save time, and reduce experimenter effects by your experiment. |
|
|
23 | |
A drawback to automating your experiments is that you may . |
|
|
24 | |
A(n) study is conducted to test the adequacy of your materials, measures, and procedure. |
|
|
25 | |
To determine whether your independent variables have their intended effects on your participants, your design should include . |
