Disadvantages And Disadvantages Of Longitudinal Studies, Cons, And Methods

The Up Series documents the lives of fourteen children in a longitudinal study. The filmmaker interviews these fourteen individuals every seven years to examine how their lives progress over time and to examine how their socioeconomic status affects their life. In this paper, Suzy will be examined from age 7 to age 56. Over the course of the Up Series, Suzy’s personality and priorities changed dramatically in almost all of the aspects of her life. From the small bits and pieces of her life that were captured and shown on the series, the course her life could have taken could have been much different. Her story shows that one life event can change the course of your whole life. In the end Suzy was the poster child of how one life event can change the rest of your life. She is not necessarily the poster child for wealth, prosperity and privilege that the series paint her to be. Initially, she was because that was the type of person the filmmaker wanted to portray her as. However, in the end, she was successful at portraying herself very differently. It took her many years to do so, but she was able to do it. By the end of the series, Suzy changed the way she portrays herself, and much of this change has to do with the life events she has experienced. She experienced being a resistant child and young adult on the series, losing a parent at a young age, finding a successful marriage and experiencing financial instability. All of these events happened at an age the made her grow

Longitudinal – several observations over a period of time. We use these types of observation if there appears to be a concern over behaviour or development.

2. How does this documentary series illustrate the disadvantages of longitudinal panel studies, as discussed in Babbie (pp. 113-114)?

13. Distinguish between quantitative and qualitative data. Which type would be presented in a data

The present study concerns longitudinal research on bullying perpetration and peer victimization. A focus is on school factors of school climate and school identification which are conceptualized related but distinct constructs.

Longitudinal research studies have also indicated that early physical abuse or neglect as a child can increase the risk of the child being antisocial or committing violent, nonviolent, or status offenses in the future.

Failure to protect subject’s personal information, is an example of not complying the above two principles in the research industry. Researchers are in a position of dealing with a great deal of very personal information that their participants have agreed to disclose. Depending on the type of study, personal identifiers such as names, birthdates, places of residence etc. may or may not have to be collected. In situations where these data are collected, researchers may take several steps to ensure the confidentiality of their participants’

* The limited sample size is a possible problem. Also, the use of longitudinal study tends to follow a subject for a very long period of time. Possibly decades. This type of study is generally used in psychology and sociology studies. Perhaps, a cross sectional study would be more appropriate as it makes

They are also advantageous in that they are much more cheaper than other studies as the data’s have already been collected and are able to to analyse and determine multiple outcomes (Mann, 2003). That is because, the collection of data is mainly the aspect that requires the use of resources. Furthermore, retrospective cohort studies also an advantage for the absence of bias as the current interest of the study was not the interest when the data was collected (Mann, 2003). Therefore, researcher bias is for the most part

| Smaller sample sizes, so less generalizable to larger populations.Not possible to create statistics – which can help to shape and plan service effectiveness and deliveryTime consumingDifficult to make comparisons within the sample.Poor re-test reliabilityResults vulnerable to researcher bias and experience.

A second disadvantage of using interpretivist methods of research is that the results are not representative. Using interpretivist research methods

Longitudinal, in which scientists study the same individuals or society repeatedly over a specified period of time

Quantitative research involves collecting data, which can be expressed numerically. The design is well structured with pre-determined outcomes. It frequently involves testing a hypothesis, which then can be analysed from the data deductively using statistical methods. Using numerical data is easier to analysis mathematical, so larger sample sizes can be utilised compared to qualitative research, therefore giving a better representative of the population; along with simplifying the process of making a generalisation. Another advantage is that studies can easily compare to similar findings (Kruger, 2003). The disadvantages are the results are limited and might not provide a proper understanding of the topic. Also, statistics and leading questions can be used to give a false representation of the data when summarising.

The drawback to cross-sectional studies is the inability to express cause and effect relationships between the variables being tested. Or to make a convincing observation in regards to the course of the connection between variables.It is because of the concept of the snapshot at the single moment, that prevents the consideration of before and after that specific moment is analyzed (What researchers mean by cross-sectional vs. longitudinal studies.,2009). As it relates to longitudinal studies, they are observational as well. However, it is over an extended period. Like cross-sectional studies, the researchers are not entering with the participants or respondents. This method studies the same subjects several times over a period of years. This technique gives the scholar the ability to measure the change of data to be collected over time. Longitudinal studies come in three prominent types panel, cohort, and retrospective. The panel study is a representative sample of participants, and the retroactive study utilizes historical data that is sometimes compared to improved

Quantitative studies are primarily numbers based. They deal with large cohort groups as well as analyze large amounts of data. “A quantitative
