Type I and Type II errors are called _______and respectively.
a. beta; alpha.
b. .01; .05.
c. a and b.
d. alpha; beta.
d. alpha; beta.
If it sounds a little like Greek, that is because it is. Alpha and beta are
the first and second letters of the Greek alphabet. A Type I (alpha
error) occurs when a researcher rejects the null hypothesis when it
is true; and a Type II error (beta error) occurs when you accept the
null hypothesis when it is false. The memory device RA (as in
"residence advisor") works well here so you can remember the
principle, as well as the sequence. Let "R" signify "reject when true"
and "A"-which comes after "R"-signify "accept when false
Which level of significance would best rule out chance factors?
a. .05
b. .01
c. .2
d. .001
d. .001
,When a researcher uses correlation, then there is no direct
manipulation
of the IV. A researcher might ask, for example, how
IQ correlates with the incidence of panic disorder. Again, nothing
is manipulated; just measured. In cases such as this a correlation
coefficient will reveal
a. the relationship between IQ and panic disorder.
b. the probability that a significant difference exists.
c. an F test.
d. percentile rank.
a. the relationship between IQ and panic disorder.
Dr. X discovered that the correlation between therapists who
hold NCC status and therapists who practice systematic
desensitization
is .90. A student who perused Dr. X's research told his
fellow students that Dr. X had discovered that attaining NCC
status causes therapists to become behaviorally oriented. The
student is incorrect because
a. systematic desensitization is clearly not a behavioral strategy.
b. this can only be determined via a histogram.
c. the study suffers from longitudinal and maturational effects.
d. correlation does not imply causation.
d. correlation does not imply causation.
,In a basic curve (bell shaped) or so-called frequency polygon the
point of maximum
concentration is the
a. mean.
b. median.
c. mode.
d. range.
c. mode.
The median is
a. the middle score when the data are arranged from highest
to lowest.
b. the arithmetic average.
c. the most frequent value obtained.
d. never more useful than the mean.
a. the middle score when the data are arranged from highest
to lowest.
Billy received an 82 on his college math final. This is Billy's raw
score on the test. A raw score simply refers to the number of
items correctly answered. A raw score is expressed in the units
by which it was originally obtained. The raw score is not altered
mathematically. Billy's raw score indicates that
a. he is roughly a B student.
b. he answered 82% correctly.
c. his percentile rank is 82.
d. more information is obviously necessary.
d. more information is obviously necessary.
, If an experiment can be replicated by others with almost identical
findings, then the experiment
a. is impacted by the observer effect.
b. is said to be a naturalistic observation.
c. is the result of ethological observation.
d. is said to be reliable.
d. is said to be reliable.
A counselor educator is teaching two separate classes in individual
inventory. In the morning class the counselor educator has
53 students and in the afternoon class she has 177 students. A
statistician would expect that the range of scores on a test would
be
a. greater in the afternoon class than the morning class.
b. smaller in the afternoon class.
c. impossible to speculate about without more data.
d. nearly the same in either class.
a. greater in the afternoon class than the morning class.
Z-scores (also called standard scores) are the same as standard
deviations, thus a z-score of -2.5 means
a. 2.5 SD below the mean.
b. 2.5 SD above the mean.
c. a CEEB score of 500.
d. -.05% of the population falls within this area of the curve.
a. 2.5 SD below the mean.
