The ""do not know"" or ""no opinion"" responses will almost always be underrepresented in the final data.

Which of the following is (are) a useful measure(s) of central tendency when the data are ordinal?

To use a chi-square test to examine cross-tabulated data, the

There is no single procedure or tool of data analysis that will avoid all erroneous conclusions.

The same analysis and observation of objective data may be subject to multiple interpretations.

In reporting two-way cross tabulation, evidence of a positive relationship between variables

The most important appeal of banners is that they allow for looking at survey questions crossed by the most important variables.

The ____ is the average of the responses computed by summing all responses and dividing by the number of responses.

In a single cross-tabulated table

The ""do not know"" or ""no opinion"" responses will almost always be overrepresented in the final data

Frequency distributions can be applied to nominal, ordinal, and interval data, but not ratio data.

Evidence of a positive relationship between variables provides evidence that the variables should be thought of as causally related.

The standard deviation tells us the range of answers that includes approximately 70% of the sampled respondents.

The mode is the response that separates the top half of response frequencies from the bottom half.

For interval data, the measure(s) of central tendency and dispersion that can be computed is(are)

The standard deviation for the responses helps assess the mean's ability to accurately reflect the sample respondents' responses.

The smaller the standard deviation the

Crossing every survey question with all the variables is useful in data analysis situations.
