Exam 15: Frequency Distribution, cross-Tabulation, and Hypothesis Testing

Which of the following statements is not true concerning cross-tabulation?

Nonparametric tests are not available in ________.

In commercial marketing research,the one-tailed test is used more often than a two-tailed test.

If the entire sample is changed by adding a fixed constant to each observation,then the mean,variance,and median change by the same fixed amount.

The ________ is the probability of rejecting the null hypothesis when it is in fact false,and should be rejected.

________ is a test statistic that measures the association between two ordinal-level variables.It makes an adjustment for ties and is most appropriate when the table of variables is not square but a rectangle.

Hypothesis tests can be related to ________.

To balance the two types of errors,alpha (α),also known as ________,is often set at .01 or .05.

The critical value of the F distribution depends upon two sets of degrees of freedom those in the numerator and those in the denominator.

The two-sample median test examines whether the two distributions are the same.

________ is a test statistic that measures the association between two ordinal-level variables.It does not make an adjustment for ties.

________ include the range,interquartile range,variance or standard deviation,and coefficient of variation.

Hypothesis-testing procedures can be broadly classified as parameter or nonparameter based on the measurement scale of the variables involved.

Suppose we wanted to test the hypothesis that the mean familiarity rating exceeds 4.0,the neutral value on a seven-point scale.The hypotheses may be formulated as ________.

The most commonly used statistics associated with frequencies are measures of location,measures of variability,and measures of occasion.

When measuring the strength of association with the contingency coefficient,the maximum value of 1 is achieved when the variables are perfectly associated.

The test statistic used in the Wilcoxon matched-pairs signed-ranks test is ________.

In the context of the Internet usage example,suppose we wanted to test whether the probability of observing a K value of .222,as determined by the normalized z statistic,is 0.103.Because this is more than the significance level of 0.05,the null hypothesis cannot be rejected.What do the results mean?

The introduction of a third variable in cross-tabulation can result in which of the following possibilities?

The last step involved in hypothesis testing is ________.
