Exam 12: Advanced Data Analysis

In using the Pearson product moment correlation, a score of -0.90 would indicate the two variables are

If costs associated with a Type 1 error are high and a Type 2 error is not costly, set the level of significance much higher, perhaps at .25 or higher.

_____, also known as trade-off analysis, is used for evaluating judgmental data where choices between attributes are involved.

Hypothesis testing involves all of the following steps except

The appropriate statistical test for hypotheses about proportions with two large samples is

In using the Pearson product moment correlation, a score of 0.13 would indicate the two variables are

The greater the costs associated with a Type 1 error, the lower we should set our maximum risk.

Canonical correlation has as its objective the identification of key descriptors on which various predefined events will vary.

Higher rs indicate higher degrees of association.

If the association between two variables is strong, you can predict one variable by knowing the other one.

Nonmonotonic association means

A Type 1 error means accepting the null hypothesis when it is actually false.

Descriptive or causal research is used to generate hypotheses.

When testing a hypothesis in any particular study, we can make either a Type 1 error or a Type 2 error, but not both.

The appropriate statistical test for hypotheses about frequency distributions with one sample and nominal data is

The significance level is the maximum risk you will accept of making a Type 2 error.

An appropriate statistical test for hypotheses about proportions is a chi-square.

_____ allows for the classification or segmentation of a larger group of variables into homogeneous subgroups based on similarities on a profile of information.

_____ allows for the prediction of the level or magnitude of a phenomenon such as market share or market size.

_____ is used to measure the degree to which two variables are correlated or associated with each other when both are nominally scaled.
