Questions On Margin Of Error

Avoiding research bias in studies is important to the development of objective, reliable information that can be used by the public. Check all of the situations that are likely to indicate research bias:

Tool validity is an extremely important aspect when gathering information used in research. There are many different tools that can be used depending on what is being researched. “Trustworthiness of the data can only be as good as the instruments or tests used to collect the data” (Boswell & Cannon, 2014). Many healthcare providers use research to increase their knowledge to help make decisions for changes in policy and procedures and in ways to care for patients.

2. select a quantitative research study. Identify and describe the method(s) used to describe the data in this study. Was the appropriate method(s) identified, in your opinion? Could other methods have been used to describe the data in this study?  Be sure to properly site the study you chose within your post.

Methodologically, the hypothesis is not founded upon methodological impartiality. One of the vital limitations is the absence of

To ensure the results of the research are ethical and valid a proper sample design is necessary. A sample design consists of methods, sample frame, and sample size.

Sampling error: The amount of confidence involved in a sample result- the amount is dependent on the size of the sample. This is significant because it can often lead to misleading poll results.

understanding. Many may argue that research does not have limitations as long as the mind has a

When researchers come up with a result to their study, it sometimes is not perfect because of the limitations. There are always limitations to every study that researchers cannot control. Identifying and explaining those important limitations will help researchers

The interval contained 13.4% III. A 99% confidence interval estimate contained 13.4% A. I and II B. I and III C. II and III D. I, II, and III E. None of the above gives the complete set of true responses. 14. The margin of error in a confidence interval estimate using z-scores covers which of following? I. Random sampling errors II.

Throughout my investigation, I was required to collect data in order to make sure that my findings, claim, and evidence were as accurate as possible. There are different ways in which I recorded my data. In order to

According to Verial (2010), “Studies usually have at least one limitation that makes some aspects of their results less likely to be accurate, such

The section on different scientific approaches was useful in that it provided a framework for how the reader can apply research principles empirically. However, many of the components that are listed as being necessary for scientific research were redundant and cumbersome to process. For example, reliability and standardization appear to be very similar terms, and it would have been helpful for the authors to more thoroughly describe the distinction between the two components.

The three things that affect the margin of error are sample size, the type of sampling done, and the size of the population. When a poll results indicates that one candidate has 54% of the voters with a margin of error 3%, I need to know more than just the margin of error. I need to know when the poll was taken, what was the sampling size, who did the samples, and how were they collected. For example with the upcoming election that is going on now, it shows that Donald Trump is leading the polls for the Republicans. They failed to show what group of people voted for him and what states are conducting this poll. The polls aren’t correct, because not all people have gotten out to vote.

Testability: Scientific research should test logically developed hypotheses to see whether or not the data supports the hypothesis that are developed after

2. Whether a study provides a significant contribution is a matter of professional judgment. What considerations should be part of this judgment?
