1
When participants are not told about the real purpose of the study
deception
debriefing
vivisection
double-blind
2
Inferential statistics can be used to determine
the mean of a set of data
the range for set of data
the likelihood the results are due to chance
if there is a normal distribution for set of data
3
A key aspect of an experiment is the requirement that researchers
provide a placebo
publish in a journal
use correlational methods
control all the conditions
4
+ correlation between # of children and life satisfaction would show those with more children
are no more satisfied than those with fewer children
more satisfied than people with less children
find less satisfaction with their lives
are less satisfied with lives than those with less children
5
The term "hypothesis" literally means
an informed hunch.
belief system.
little theory.
prediction.
6
A hypothesis must
be testable and falsifiable.
define the independent and dependent variable.
be proven true.
identify the randomization process.
7
In science, a theory
always generates accurate findings.
is a testable explanation fora set of ovservations.
is based on several experiments
is diametrically opposed to emiricism
8
Measurements that use numbers to shwe levels, size, intensity, or amounts of a variable are
covariable
standardized
quantified
correlated
9
If lighter people tend to whistle more than heavier people, the correlation is
negative
positive
minimal
zero
10
In comparing a theory and a hypothesis, it is noteworthy that
you can prove that both of them are true.
theory = scientific information a hypothesis = speculation.
a theory is testable, but a hypothesis is not.
hypothesis can be specific prediction related larger theory.
11
Difference between experimental group and control is whether they
receive special treatment of interest
are measured by the researcher
are in double-blind study
receive DV
12
Students sitting in front row get higher grades than those sitting further back.is example of
theory.
hypothesis.
dependent variable.
correlation coefficient.
13
If a study is conducted through empirical investigation, this means
It is conducted in a research laboratory.
It is based on careful measurements and direct observation.
It is conducted by a psychologist who is a trained PH.D.
It is conducted in a research laboratory.
14
Randomization
is good way to define dependent variable
ensures studies can be replicated
difficult to achieve in reserch
reduces experimenter bias
15
Variables that should be controlled by keeping them the same or constant
independent
confounding
dependent
placebo
16
If the results rise to the level of statistical significance, this means that the results
likely result of manipulation of IV
cannot be replicated
occurred because of manipulation of control group
are probably due to chance
17
Random assignment means
every participant is placed in control group
participants should not know to what group they belong
participants select which group they would like to join
participants have equal chance of being in control or exp gp
18
To determine that the results are due to IV the results must reach level that is
clinically significant
quantified
significantly below chance
of clear importance
19
a large p value, p>.50, means
the data was valid
high probability results were by chance
all of the above
data was reliable
20
Will computer-aided learning produce higher test scores than lecture. Independent variable is
method of instruction
students
test scores
students' previous grades in psych
21
The independent variable
is what one is trying to measure in a study
is the condition that the researcher manipulates
must be testable
is the group that receives treatment
22
Testing if money can buy happiness. In this study money is
independent variable
dependent variable
hypothesis
control group
23
Which of the following are examples of descriptive statistics EXCEPT
mean
statistical significance
mode
range
24
The experimenter allows preconceived notions about what "should" happen in an experiment
expectancy bias
confounding variable
personal bias
observer bias
25
Which study best determines if people's intelligence remained the same over course of life-span
longitudnal
naturalistic
survey
cohort-sequential
26
The independent variable __, as the dependent variable__.
controlled by researcher; measured outcome of the study
measured outcome; controlled by researcher
is measured outcome; is the group does not get treatment
group that does get treatment;group that does not
27
What is the role of an Institutional Review Board?
none of the above
ensure all research adheres to ethical guidelines
see if IV is impacting the outcome of the study
ensure experiment's hypothesis is proven true
28
Which of the following measures of central tendencies is most effected by extreme scores?
median
mode
standard deviation
mean
29
Why is it impossible to have p=00?
never use a completely random sample
none of the above
always correlation between 2 variables
studies have small likelihood results were by chance
30
must be stated in terms of how the concepts are measured and what techniques will produce them
dependent variables
control groups
theories
operational definitions
31
A full and honest account of purpose of a study at its completion
deception
debriefing
informed consent
IRB approval
32
how are a sample and population different from one another?
population is smaller than sample
population is chosen randomly
sample is made of no more than 10 participants
sample is smaller than population
33
Which of the following is not a disadvantage of correlational studies?
subjects cannot be assigned randomly to various conditions
one can never ensure groups are similar in every way
researchers must give up some control of research
results apply to world outside lab
34
What is standard deviation?
middle score
score that occurs most frequently
whether or not data collected is valid
average distance of set of scores from mean
35
If a set of data has relatively low variability, this means the scores
have negative correlation
have zero correlation
are statistically significant
are closely clustered around the mean
36
Why is it important to replicate studies
all of the above
ensure results are valid
ensure experimenter bias did not influence study
endure results did not occur due to chance
