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 z-score.
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 z-scores 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 left-hand 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.
