Question 1

What criteria do qualitative researchers use to assess the quality of a study?

Accepted Answer

Qualitative researchers often use dependability to assess the quality of a study, which parallels reliability in quantitative research.

Question 2

What criteria do quantitative researchers use to assess the accuracy and consistency of information obtained in a study?

Accepted Answer

Reliability is the criterion used by quantitative researchers to assess the accuracy and consistency of information obtained in a study. It refers to the degree to which an assessment tool produces stable and consistent results.

Question 3

What refers to evidence of the researcher's objectivity?

Accepted Answer

Confirmability refers to the degree to which the results could be confirmed or corroborated by others, demonstrating the researcher's objectivity and neutrality in the research findings.

Question 4

A thermometer measured a child's temperature as 98.1°F one minute and as 98.1°F the next minute. What can we assume about the thermometer?

Accepted Answer

The thermometer is reliable because it provided consistent results over multiple measurements.

Question 5

What is achieved when the research methods engender confidence in the truth of the data and the researchers' interpretations?

Accepted Answer

Credibility is achieved when research methods instill confidence in the truth of the data and the researchers' interpretations, ensuring that the findings are believable and accurately represent the participants' perspectives.

Question 6

Qualitative researchers discuss methods of enhancing the study's data by what method?

Accepted Answer

The answer of Qualitative researchers discuss methods of enhancing the...

Question 7

Which can cause bias in a study?

Accepted Answer

Researcher subjectivity can introduce bias into a study by affecting how data is interpreted, collected, or analyzed based on personal beliefs, expectations, or experiences.

Question 8

A researcher finds that a small number of subjects did not provide accurate information because they had just completed a rigorous session with the physical therapist. What is this an example of?

Accepted Answer

This is an example of random bias, as the inaccuracy in information is due to a random factor (the subjects' recent physical activity) rather than a systematic error in the study design.

Question 9

A spring scale consistently measures people's weights 4 pounds lighter than their true weight. What type of bias would this data be on the weight?

Accepted Answer

Systematic bias occurs when there is a consistent, repeated deviation from the true value in one direction, as seen with the scale consistently under-measuring by 4 pounds.

Question 10

The researcher wants to explore the extent to which qualitative findings can be transferred to other settings. What is this called?

Accepted Answer

Transferability refers to the extent to which the findings of a qualitative study can be applied or transferred to other contexts or settings. It is a concept used to evaluate the applicability of research results to other situations.

Question 11

What is the process of reflecting critically on the self and of scrutinizing personal values that could affect interpretation?

Accepted Answer

Reflexivity involves reflecting on oneself, particularly on how one's own experiences, biases, and values may influence research or interpretation. It's a critical self-examination process to ensure objectivity and awareness in research or analysis.

Question 12

The researcher wants to explore the extent to which quantitative findings can be applied to other groups and settings. What is this called?

Accepted Answer

Generalizability refers to the extent to which findings from one study can be applied to other groups, contexts, or settings, indicating how broadly the results can be considered applicable.

Question 13

What is concealing information from participants, research agents such as data collectors, care providers, or data analysts to enhance objectivity called?

Accepted Answer

Masking, also known as blinding, is a technique used in research to prevent bias by concealing information from participants, research agents, data collectors, care providers, or data analysts. This enhances the objectivity of the study.

Question 14

A researcher uses multiple sources or referents to draw conclusions about what constitutes the truth. What is this called?

Accepted Answer

Triangulation involves using multiple data sources, methods, investigators, or theories to cross-check and validate findings, enhancing the credibility and depth of the research outcomes.

Question 15

A researcher designs a study to determine if a new teaching modality will benefit a particular group of special education students that the researcher has been working. Which design would the researcher be most likely to use?

Accepted Answer

The researcher is likely to use a design that compares the same group's status under different circumstances, such as before and after the implementation of the new teaching modality, to determine its effectiveness.

Question 16

What technique is the researcher using to control extraneous variables to the study purpose that can obscure understanding?

Accepted Answer

Confounding is a technique used to control extraneous variables that can obscure understanding by identifying and controlling for variables that could potentially influence the results of a study.

Question 17

Researchers often incorporate comparisons into their designs to enhance interpretability. What occurs when different groups of people are compared?

Accepted Answer

When different groups of people are compared, it is referred to as a between-subjects design, where each group experiences different conditions or treatments.

Question 18

A study addressing quality of life of a group of patients who had undergone various treatments for coronary artery disease was gathered 1 year and 8 years after their treatment. What type of study is this called?

Accepted Answer

This is a follow-up study as it involves observing the same group of patients over a period of time to assess changes in their quality of life after treatment.

Question 19

A researcher is conducting a small-scale trial run designed to test methods to be used in a larger, more rigorous study. What type of study is this called?

Accepted Answer

A feasibility study is conducted to evaluate the practicality and viability of the methods and procedures planned for a larger, more comprehensive study. It helps in identifying any issues or challenges that might arise during the actual study, allowing researchers to make necessary adjustments beforehand.
