Explain each sampling technique discussed in the “Visual Learner: Statistics” in your own words, and give examples of when each technique would be appropriate.

One of the most important steps of the research process is developing a resarch question. Research questions direct your investigation and provides a clear goalto focus on (research question is “a question that a research project sets out to answer “. Choosing a research question is an essential element of both quantitative and qualitative research. Investigation will require data collection and analysis, and the methodology for this will vary widely. Good research questions seek to improve knowledge on an important topic, and are usually narrow and specific (Mattick, et al., 2018).

The questions may come in these forms:

How big was the sample?

 

Answer:

In general, the more the participants in a study, the more valid its results. That said, a large sample is sometimes impossible or even undesirable for certain kinds of studies. This is especially true I’m expensive neuroscience experiments functional magnetic resonance imaging, or MRI,scans.

 

Was there a control group?

 

Answer

One of the first things to look for in methodology is whether the sample is randomized and involved a control group; this is especially important if a study is to suggest that a certain variable might actually cause a specific outcome, rather than just be correlated with it.

For example, were some participants lectured on proper hand hygiene while others weren’t? If the sample is large enough, randomized trials can produce solid conclusions. But, sometimes, a study will not have a control group because it’s ethically impossible.

 

Does the researcher seem to have an agenda?

 

Answer

 

Readers could understandably be skeptical of effectiveness of hand hygiene in preventing infection and promoting health. It doesn’t automatically mean that the conclusion on this are wrong. It does, however, raise the bar for peer review and replication.

Bernadette,

Good questionnaire!!! Your questions including samples, control group, and agenda were remarkable.

Bernadette,

A research question is an inquiry an individual uses as the main focus of an examination. It addresses a problem or issue the researcher plans to answer upon completion of their study. Writing a research question is the first step in a research project, building the foundation for an exploration. Individuals use research questions for various types of research studies, such as experimentalqualitative and observational

 

Researchers answer this question by conducting analyses and interpreting data.

When creating a research question, you can consider several components to include in your wording. Brian Hulley created the FINER model, which stands for the following characteristics of a research question:

  • Feasible: The question is within a researcher’s abilities and resources to examine, collect data and answer.
  • Interesting: Keeping in mind peers who review this research project, researchers create research questions on fascinating topics.
  • Novel: A research question provides new insights in the field of study investigated and may help confirm existing research.
  • Ethical: The topic is something review boards and authorities approve, meaning the recruitment and participation of individuals in the study follows informed consent rules.
  • Relevant: Researchers choose topics related to their industry and the public’s interest, leading to visible changes in society.

Hi Bernadette

There are different things to look at when evaluating a research paper especially on the selection of the participants. The first questions to ask about a paper are those that are related to the topic or subject that is being researched. A clear statement towards the opening of a paper describing what issue the study is attempting to answer should be included in the document. This is something that authors often forget until they are halfway through the article (Yong & Pearce, 2013). Indeed, some authors choose to exclude it entirely, maybe on the assumption that it is self-evident or simply failing to recognize that, although it may be clear to the author, a reader with no prior knowledge of the work will only have the paper to go on.

Hello Bernadette,

In addition, with a large enough sample size, a simple random sample has high external validity: it represents the characteristics of the larger population. However, simple random sampling can be challenging to implement in practice. To use this method, there are some prerequisites: You have a complete list of every member of the population. You can contact or access each member of the population if they are selected. You have the time and resources to collect data from the necessary sample size.

Simple random sampling works best if you have a lot of time and resources to conduct your study, or if you are studying a limited population that can easily be sampled. Good Job.
