Hypothesis Testing--$100
This always specifies that the
treatment had no effect or made no
difference.
answer
Hypothesis Testing--$200
Hypothesis testing is said to be this
kind of a process because sample
data is used to make decisions
about a population.
answer
Hypothesis Testing--$300
Rejecting the null hypothesis when,
in fact, the null hypothesis is true.
answer
Hypothesis Testing--$400
Retaining the null hypothesis when,
in fact, the null hypothesis is false.
answer
Hypothesis Testing--$500
Rejecting the null hypothesis when,
in fact, the null hypothesis is false.
answer
T-test Basics--$100
Use a t statistic instead of a z
statistic when this is not known.
answer
T-test Basics--$200
The shape of the t-distribution is
determined by
answer
T-test Basics--$300
In general, a t-test can be
expressed as this ratio.
answer
T-test Basics--$400
Use this kind of t-test when
comparing a single sample to a
hypothesized population value.
answer
T-test Basics--$500
The alternative hypothesis for a
two-tailed t-test comparing the
mean of one sample to a
hypothesized population mean of
450 ms.
answer
Independent Samples--$100
Another name for an independent
samples design.
answer
Independent Samples--$200
The number of scores contributed
by each participant in an
independent samples design.
answer
Independent Samples--$300
In an independent samples design,
this special calculation of variability
must be computed and used to
figure the estimated standard error.
answer
Independent Samples--$400
A simple average of the group
variances can be used to calculate
estimated standard error only when
__________.
answer
Independent Samples--$500
For an independent samples
design, if df=18 the total number of
participants must be ___.
answer
Z-scores-$100
The z-score that would indicate a
score located 2 standard deviation
units below the mean.
answer
Z-scores--$200
If a person earns a score that is
equal to the population mean, that
person’s z-score will be ___.
answer
Z-scores--$300
The distribution of z-scores always
has a standard deviation of ___.
answer
Z-scores--$400
The two pieces of population
information you need in order to
transform a raw score into a zscore.
answer
Z-scores--$500
If the original distribution is
negatively skewed, the shape of
the distribution after a z-score
transformation will be
___________.
answer
Probability--$100
In general, the probability of A is
computed by taking __________
and dividing by ________.
answer
Probability--$200
For the definition of probability to
be accurate, the outcomes must be
obtained by a process called
___________.
answer
Probability--$300
Provides a complete listing of zscores and their corresponding
proportions of the normal
distribution.
answer
Probability--$400
The _____ always corresponds to the
larger part of the distribution, whether it
is on the right-hand side or the lefthand side of the distribution.
answer
Probability--$500
When finding the ______ for a
particular score, we are always
looking for the proportion of the
distribution to the _____ of the x
value.
