Exam 10: Clarifying Measurement and Data Collection in Quantitative Research

A researcher may use which strategy to reduce the potential for measurement error when evaluating obesity in study subjects?

A researcher administers two instruments known to measure opposite concepts and performs correlational analyses on the results.The original measure has a negative correlation of ?7?0.6 with the new measure.This indicates:

A researcher evaluating the weight of subjects who are obese ensures that the scales used are maintained and calibrated according to the manufacturer's recommendations.This is to ensure:

A researcher performs a series of pilot studies to evaluate whether a measurement tool produces consistent results.This is an evaluation of:

What type of information is typically found in an administrative database?

Which can be measured using direct measurement?

A screening test has a specificity of 92%.This means that there is a(n):

Which generally is an advantage of using primary data in a research study?

Which is true about using data from an existing database?

A researcher studying children identifies the following age groups: $\quad$ Birth to age 12 months $\quad$ 12 months to 3 years $\quad$ 3 years to 5 years $\quad$ 5 years to 12 years $\quad$ 12 years to 18 years These categories are not:

A study measuring the effects of a new diuretic medication records hourly urine output of subjects.This measure represents which level of measurement?

A researcher develops a new instrument to measure coping skills and conducts a pilot study to compare the new tool with an existing tool that measures this concept.This is an example of evidence of validity from:

A researcher wishes to evaluate the reliability of a visual analog pain scale in a group of postoperative patients.The best way to do this is to compare results:

In a pilot study to help train a group of data collectors who will evaluate children's pain using a FACES rating scale,the researcher examines the reliability of the scores of each data collector.This is an example of which type of reliability measure?

Which is true about a test that is highly sensitive for detecting a disease?

A researcher evaluates scores of a paper and pencil instrument with dichotomous variables using the Kuder-Richardson formula.This is a test of:

Which data represent the lowest form of measurement?

Which statement is true about using a questionnaire to collect data?

When documenting reports that previous research has demonstrated the accuracy of a physiologic measure,the researcher is addressing the measure's:

Among subjects with coronary artery disease,a researcher identifies three levels of symptoms which can be categorized by severity.This represents which level of measurement?
