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