Essay On Population Assessment

Define the term population at risk and indicate which of the elementary students are not at risk

Validity refers to whether the research conducted is what it intended to be. Validity involves dependability, which means, a valid measure must be reliable. But, reliability doesn’t have to link to validity, a reliable measure is not required to be valid.

For any measure to be valuable in psychological research, it needs to be both valid and reliable (Goodwin, 2008: 128). Research is reliable when more researchers have found the same results, or, within for instance behavioural research, when the same behaviour occurs at several measurements (Goodwin, 2008: 124). There are different types of validity. Firstly, there is construct validity, which measures whether an operationalisation of a construct actually measures what it is supposed to measure. Secondly, criterion validity determines whether a certain phenomenon is related to another phenomenon, and can accurately determine future developments. Lastly, content validity determines whether a test measures all aspects of the construct that is being measured (Goodwin, 2008: 125-126).

In the text book, “Theories and Research of Personality” written by Daniel Cervone and Lawrence A. Pervin, the authors talk about the goals to research and they are referring to reliability, validity, and ethical behavior. With reliability, the author is referring to the “extent to which observations can be replicated and whether the measures of the research are dependable or stable” (Cervone, Pervin 43, 2013). Reliability is extremely important to have when conducting research because if the research conducted is not reliable then when trying to get research out to people, other psychologists will not believe what you are trying to get across and in the long term affecting ones career. Also Cervone and Pervin talk about validity which is,

As noted in the table above, principal surveys will be conducted and used to gather both quantitative and qualitative data. A sample of the teacher exit slip interview can be found in Appendix A. A sample of the Principal survey can be found in Appendix B. A sample of the Administrator interview questions can be found in Appendix C. In the next section, the method of collecting these data is described in detail.

In psychological assessment of any kind, validity is defined as “the degree to which all the accumulated evidence supports the intended

Validity is the degree to which an instrument measure what it is purports to measure. Invalid instruments can lead to erroneous research conclusions, which in turn can influence educational decisions. Reliability is the internal consistency or stability of the measuring device

1. State the type of study that was conducted (see methods section of article, it must be one of the above study types).

52). When writing your report it’s important to write it with clarity so that anyone can read it and go out and do the research without having to ask you what you did. Another element for good research design is validity which is how well the study measures what it was designed to measure “the extent to which an instrument measures what it is intended to measure” (Conley,. pg.

To gain sufficient depth and representative results of the UK infancy population, this research will utilise a sample size of 5,000 infants. Additionally, five analyse sites geographically across the UK will be used for the outcome measure testing, and theses site will be located in London, Birmingham, Cardiff, Newcastle, and Glasgow. The research will be recorded at these sites during the 2-year period. Mother will be recruited as healthy women and no medical history, categorized by age boundaries of 27 to 32 years old. Since the women who aged above 35 years old would have a greater risk of general maternal health problems such as high blood pressure, pre-eclampsia, which can contribute to complications for both mother and infant. Infants are singleton healthy based on full term, which is 32-42week, weighing ≥2.5 kg at birth, to avoid to disperse the amount of breast milk in case of twin or triplets.

The researchers gathered data from two school districts within the local area. A corresponding control sample of 300 students

The reasoning behind the population is that researching the entire United States is a huge feat and one that is not necessarily needed. Having an exploratory study for just Midwestern states is a good starting point, but is also broad enough to be generalizable. For the sample of State Patrol K9 Units, this is probably one of the best ways to study broader K9 unit forces. Some states have specific regulations for what dogs can be on their force, so only one state being studied would be ineffective. Having only the state patrol lessens the bias and we are more able to compare it to other similar state structures. Having a larger sample size ensures accuracy and will allow us to have more states involved since some states have more units than others, so the states with less will have a better chance of being represented. Systematic Sampling is the best method since this population is fairly accessible and extremely publicized, non-probability sampling is not needed. Randomization will ensure that the dogs and departments are not chosen based on bias. Lists are easily obtained and police dogs tend to be showcased so information gathering should not be an issue. Participants would be recruited via email and phone for surveys. Also, department heads would be contacted in order to reach the officers/handlers. A potential problem consists of getting participants to find time in their schedule. Police work is 24/7 so these people would need to take time out of their schedule to help

The study will be conducted in Isiolo central Division, Isiolo County- Kenya. Administratively, Isiolo is located in Eastern Province and covers an area of 25 698 km2. It borders Marsbit District to the North, Garissa and Wajir Districts to the South East and East respectively. It also borders Tana River, Nyambene and Meru Districts to the South and Laikipia and Samburu Districts to the West. It is geographically located between longitude 36o 60`E and 38o 50` E and Latitude 0.5o N and

For the first target population of this study (i.e boarding senior secondary schools), a simple random sampling was employed to select six (6) schools. Thereafter, three (3) biology teachers were randomly selected from each of the sampled boarding schools. Also for the second target population, a simple random sampling was adopted to selected six (6) non-boarding senior secondary schools. Thereafter, three (3) biology teachers were randomly selected from each of the sampled schools.

As the part of the MUSKAAN PROJECT run by ANKUR YUVA CHETNA SHIVIR, we were asked to collect the data of different villages and government schools of our respective blocks. Our supervisor gave us the format of village and school profile and asked us to collect the data accordingly.
