Exam 14: Basic Data Analysis

The type of measurement scale used in the research study determines the possible statistical tests that can be used appropriately with the resulting data.

Scores or observations recalibrated to indicate how they relate to a base number are referred to as _____.

Researchers usually are most interested in the marginals in a contingency table.

The row and column totals in a contingency table are called subtotals because they are less than the total.

Tabulation refers to the orderly arrangement of data in a table or other summary format.

The researcher using sampling runs the risk of committing two types of errors: primary errors and secondary errors.

The arrangement of data into a row-and-column format that gives the number of responses for each category of the variable is known as a(n)______ table.

The process of changing data from its original form to a format that more closely matches the research objectives of the study is called data ______.

Another name for data transformation is _____.

Compare and contrast Type I errors and Type II errors and explain which one is of more concern to researchers.

When a researcher combines the "Strongly Disagree" and "Disagree" responses on a Likert scale item to a single "Strongly Disagree/Disagree" percentage,this is an example of _____.

When the responses to two survey questions are presented as a cross-tabulation of the two variables studied in these two questions,the result is called a(n)______ table.

Scores or observations recalibrated to indicate how they relate to a base number are called _____ numbers.

Counting the number of responses to questions in a survey by hand is called _____.

Researchers often perform a(n)_____ to collapse a scale with multiple response points into two categories.

The critical probability associated with a statistical hypothesis test that indicates how likely it is that an inference supporting a difference between an observed value and some statistical expectation is true is called _____.

Breaking down the answer to the question: "Have you ever purchased a ticket online for an American Airlines flight?" into subgroups based on gender and zip code is an example of _____.

A two-way contingency table is referred to as a(n)_____ table.

When a researcher sets an acceptable significance level a priori (a),he or she is determining how much tolerance he or she has for which type of error?
