This review discusses how to critique a research study. Against the backdrop of health science research, with a strong clinical bias, the review discusses study design, outcome analyses and research relevance. Some global aspects of statistical analyses of the data is also provided. The aim of the review is to help dissect resea
What is the purpose of a literature search in preparing a research proposal? What demonstrates an adequate literature search?
Using the following scenario: There are 500 people in Chicago who suffer from a particular condition.

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
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
Why is the sample size in most qualitative studies smaller than that used in quantitative ones?

Please describe what the study tool of observation is? Please provide references.
Describe stability in reference to reliability?
Please describe the study tool of scales and interviews ?
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
Find the Reliability and Validity in the article attached.
What is the difference between instrument validity and reliability? Please give examples of each.
When dealing with extraneous variables what types of subject controls can be used?
Internal validity would be results of the study that are evidenced based on reality and not on supposition. External is more broad and can be generalized. An example of internal validity would be a research study with a 100 group sample of diabetics that trialed a new diabetic sock and found it to be comfortable with minimal ski
Can you describe retrospective versus prospective study designs? What are examples of this?
What is a extraneous variable? Can you give me an example of this?
Can you describe the study design of experimental and quasi-experimental? What is the difference? Are there any examples to relate this to?
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
What is the difference between external and internal validity of research study design? This job gives an example to understand these terms.
Can someone explain the difference between Qualitative and Quantitative research in a nut shell?

I am a doctoral student. I am doing a research project where I have data from 2 questionnaires. This first questionnaire assesses the personality types of audiologists (four general categories).

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
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
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
