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
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
Ancient History--\$100
This means “two names,” referring
to a scale consisting of exactly two
categories.
answer
Ancient History--\$200
Use this to look up the proportion of
the normal distribution
corresponding to a particular zscore.
answer
Ancient History--\$300
Use this research strategy to
describe the relationship between
two variables.
answer
Ancient History--\$400
A researcher administers the same
drug to 3 groups of participants, with
each group confined to a room with a
different temperature—60, 70, and 80
degrees respectively. What is the
independent variable and how many
levels are there?
answer
Ancient History--\$500
The z-score distribution will always
have a mean of ___ and a standard
deviation of ___.
