Evaluation, Measurement and Research Methods

Sampling Techniques, Measurement, Reliability, and Validity

Using the following scenario: There are 500 people in Chicago who suffer from a particular condition. You want to survey these people and you decide that since the survey instrument is long, you will give a monetary incentive of $15 to each of the individuals who completes the survey. You only have enough money to pay 45 pe

Methods of Research In Public Health Criteria for the Evaluation of a Research Study For this Discussion Forum use the following scenario: You are asked to read a research article from a psychology journal and evaluate whether or not in your opinion the study is a good one. It is not always an easy task to evaluate the work of another.

Intro to random sampling question

I have been given a data set with the heights (in cm) of 200 Mexican children ages 2- 10 years. Each child has an ID number at the column to the left. For the purposes of this assignment, I will think of the 200 children as being a population of children from some town in Mexico. I will need to estimate the average (mean) height

Health assessment cases are noted.

1) Describe how you would conduct a health assessment and a physical exam on a 19 year old male with complaints of scrotal pain. Explain why you would choose to conduct it in the manner you describe. 2) What physical assessment findings would be likely in a patient with appendicitis? What if the patient were pregnant?

Differences between the types of research studies

There are differences between the types of research studies. 1. Which one has research questions that are broad? 2. Which type has no hypothesis? 3. Which type allows research questions evolve as the study progresses? 4. Which type has follow-up based on responses? Please provide help and guidance for th

Validity and reliability of the Yale Physical Activity Survey in Spanish Elderly

I am writing a report, there are some questions I do not understand. Please explain 1. How did the researchers assess the RELIABILITY of this survey, & what did they find? 2. How did the researchers assess the VALIDITY of this survey, what did they find, how can the validity of physical activity questionnaires be address

Extraneous Variables

When dealing with extraneous variables what types of subject controls can be used?

Study design types are defined.

Can you describe the study design of experimental and quasi-experimental? What is the difference? Are there any examples to relate this to?

Internal validity - threat

What would be a threat to internal validity? What is an example? Validity in research study design usually refers to the tools used to measure aspects of the research question, for example a questionnaire is used in survey design and is said to have 'internal validity' if the questions are precise enough to get answers which

Research Question and Purpose Statement

Compiling and presenting a rigorous literature review

Many students find it difficult to write a rigorous literature review, which is an essential starting point for any study. They can often identify papers and write a brief description of what they are about, but omit some important points. They do not understand the purpose of the review for their particular study so are too

Understanding Frames of Reference in research

Students and novice researchers often find it difficult to construct a Frame of reference ( sometimes known as a research framework or algoithm) because they do not understand the purpose of the Framework or its derivation. This solution sets out the purposes of Frames of Reference, both theoretical and conceptual and

Differences betweenTheoretical and Conceptual Frames of Reference

Students and novice researchers often have difficulty in constructing a Frame of Reference for their study. This is an essential element in the research process as it links the study to the wider body of knowledge involved and helps to clarify the concepts and theories used with reference to the chosen research methods. This so
