Observations and Measurements

I am a member of the infection disease council at my workplace and have seen benefits and drawbacks with the monthly hand hygiene audits that I have performed over the past years. The data is gathered from an observation method that requires us to monitor at least ten health care workers and their compliance with proper hand hygiene techniques in their nursing units. Meaningful and descriptive data is collected by a trained observer’s eye that monitors workers…

participants’ academic scores were observed, since they were all undergraduate students. In each study, the researchers measured the scores of the participants twice in order to determine whether there was a difference in their depression levels. The first measurement occurred at the beginning of the study and the second a few months afterwards. They discovered that though there was no difference between men and women about their fantasies, the number of symptoms each gender suffered differed.…

A naturalistic observation is a type of qualitative research methodology in which a researcher carries out a study by carefully observing the subjects in their natural environment (Cozby & Bates, 2012; Creswell, 2013). Naturalistic observational research is deeply deep-rooted in the discipline of anthropology particularly in studies examining human and animal behavior. It is also widely used in other social science disciplines like sociology and ethnic studies (Cozby & Bates, 2012). Bowler et al…

each. • The steps of the scientific method are observation, define problem, construct a hypothesis, test the experiment/ gather evidence, and draw a conclusion. Observation is the procedure of collecting information about events and processes carefully. It involves with seeing and hearing. Defining the problem is when you identify a conflict that requires a solution to be solved. A hypothesis is a proposed explanation based on the evidence and observation. Testing the hypothesis is when we…

The most likely source of systematic error is parallax error. It is highly likely that measuring the length of the tube was affected by the positioning of the ruler against the tube as well as the eye against the ruler. The absence of millimetre measurements on the ruler also required the observer to estimate to the nearest millimetre which also likely resulted in inaccuracies. The mouth of the tube was also rigid which has possibly had an effect on the end correction value of 0.4d, however this…

Some of the aspects from these three articles can advance the understanding and the validity of Merton’s anomie theory. When looking at the study done by Baumer and Gustafson, the quality of their study is very sound. The researches find a way to measure the different parts of Merton’s theory, such as legitimate employment and other things that would be considered blocked opportunity and crime, and measure them (Baumer & Gustafson, 2007). Baumer and Gustafson also give solid background…

Based on this calculation, would timing more drops help in reducing the uncertainty of the average times? In this experiment would it be feasible to take the optimal number of measurements? In my works, there are at least 5 times of each ball to measurement need. With the calculation, If student timing more drops, it will help in decreasing the uncertainly of the average time. So, 5 times of dropping are enough for this experiment. Q9: Were the times given by the…

Sources of Measurement Error Measurement is the process by where we assign value to empirical events, objects or properties, or activities according to a set of rules or standards (Cooper & Schindler, 2014). The goal of measurement is to represent the events, objects, properties, or activities with complete precision and control. Because a researcher does not have complete control, errors do occur. Measurement error is the difference between the research value assigned and the true…

As discussed previously there has been various methods developed in the past few decades for performance measurements; however the most acceptable and regarded approach is the "Balanced Scorecard Approach". Balanced Scorecard addresses one major issue that financial measurement tools are insufficient to guide companies for success. It provides a broader sense of indications for the total value creation in organizations through tangible and…

be valued or construct to get detailed characteristics of a person. As we cannot physically see the traits, there will be a question about is it really there or true? Scientists made some interference about people and how they are like and such measurement are hypothetical most of the times. Smith (2005) was explaining in his study that even though those theoretical theories are there, it is necessary to make sure they are measure “in a convincing, valid way” (P. 396). Validity is important and…
