difference.
answer
Hypothesis Testing--$200
Hypothesis testing is said to be this

answer
T-test Basics--$300
In general, a t-test can be
expressed as this ratio.
answer
T-test Basics--$400

two-tailed t-test comparing the
mean of one sample to a
hypothesized population mean of
450 ms.
answer
Independent Samples--$100

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

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
Repeated Samples--$100
Another name for a repeated
samples design.
answer
Repeated Samples--$200
The number of scores contributed
by each participant in a repeated
samples design.
answer
Repeated Samples--$300
A variant of the repeated samples
design in which great care is taken
to minimize individual differences
between two participants.
answer
Repeated Samples--$400
The null hypothesis for a two-tailed
test in a repeated samples design.
answer
Repeated Samples--$500
In a repeated samples design, the
estimated standard error is reduced
because this can be removed.
answer
