a. TRUE
- Which of the following is (are) a useful measure(s) of central tendency and dispersion when the data are ratio?
a. Mode, median, mean, standard deviation, geometric and harmonic mean
- The smaller the standard deviation the:
a. Closer are the actual responses to the mean
- The measures of interval data include the mode, mean, and median.
a. TRUE
- The standard deviation represents the degree of spread of responses among the response categories.
a. TRUE
- For ratio data, the measure(s) of central tendency and dispersion that can be computed is (are):
a. Mode, median, mean, standard deviation, geometric and harmonic mean
- In reporting two-way cross tabulation, evidence of a positive relationship between variables:
a. Does NOT provide evidence that the variables are causally related
- In terms of frequency distributions and percentages,
a. Percent’s cannot be averaged unless the percentage is weighted by the size of the sample responding to the question
- The measures of interval data include only the mode and the median.
a. FALSE
- Important aspects of the use of percentages include:
a. A and B
- The median is:
a. The response that separates the top half of response frequencies from the bottom half
Qualitative analysis is guided by universal rules.
FALSE, It is NOT
In thematic analysis, themes should not be directly evolved from the research questions predetermined before the data collection began.
FALSE
Step 5 in analyzing qualitative data is
Conclusion drawing and verification
Qualitative research examines consumer buying behavior to answer questions regarding why consumers buy goods and services.
TRUE
The researcher has to make sense of the information that has been gathered in a qualitative research study
TRUE
Qualitative analysis is a fluid process that is highly dependent on the evaluator and the context of the study.
TRUE
Researchers examining qualitative data should NOT be concerned with interesting anecdotes that surface from the data.
FALSE
If the manager only needs to know what occurred, or how often, then qualitative research would meet the researcher’s needs.
FALSE
It is the job of the evaluator to examine the ____ data and decide what is important.
RAW
Netnographic data analysis begins with opening coding, then axial coding, and ends with selective coding.
FALSE
In using the Pearson product moment correlation between 0.41 and 0.60 would indicate a ______ correlation.
weak to moderate
In using the Pearson product moment correlation, a correlation greater than 0.80 would indicate a ______correlation.
very strong
The null and alternative hypothesis are competing hypotheses, therefore, only one can be true.
TRUE
Statistically significant difference are significant enough to influence management decisions.
FALSE
_____ is used to measure the degree to which two variables are correlated or associated with each other when both are ordinary related.
Spearman Rank-Order Correlation.
For variables that are ordinal, association is measured using the Spearman rank-order correlation.
TRUE
Multiple regression allows for the prediction of the level or magnitude of a phenomenon such as market size or market share.
TRUE
Multidimensional scaling techniques result in perceptional maps that describe the positioning of companies or brands that are compared relative to the position they occupy in the minds of customers according to key attributes.
True
The Pearson product moment correlation is used to measure the correlation of:
Internal or Ration Data
Multivariate Analysis simultaneously analyzes multiple measurements of attitudes, attributes, or behavior.
TRUE
The findings section of the report is normally the largest section of the report and should be organized in a logical way.
True
A Bar chart:
Easily constructed and can be readily interpreted even by those not familiar with charts.
The research methodology section of the report should include a specific discussion of the analysis process.
FALSE, GENERAL discussion
An analytical table is designed to be a repository of statistical data.
False
Binding the final report is recommended due to it is a relatively inexpensive way to add both value and protection to the report.
TRUE
The introduction section of the report should refer the reader to the basic purpose of the research and the specific objectives that were agreed upon in the research proposal.
