be replicated in a different college setting. The research may only prove to be positively affecting

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.

Problem: Professors with limited resources usually find it difficult to obtain adequate samples of the general adult population for their research. Instead, many study samples of college students, who are readily available, even though there is no reason to believe that samples of college students are representative of the national population of adults. (Of course, often professors are interested in the behavior of college students only, in which case, using college students is not a problem.)

How can you improve this campus by letting become more diverse? For example, a majority of students are high school graduates, rather than college transfers.

If I were asked to enroll my child in a longitudinal study, then I would have to think long and hard about it. These studies have many different components to them that a parent may not want for their child, such as how long the study takes and how the child is tested. These studies last for a long period of time, for example page 43 in the textbook talks about a man named Lewis Terman who began a study 80 years ago and is still continuing today. I personally would not be interested in my child participating in an 80 plus year long study. I would also be interested in learning about the testing before I enrolled my child, such as how frequent, how hard, and how long the tests would be. I want my child to be able to live a normal life and

In the modern age of health,education and public safety, society relies on rigorous research methods to find answers to complex issues dealing with social issues and general concerns. Ultimately, some short-term research methods may initially fail; however, continued extended research should surely result in success and benefit future generations. Depending on the topic of research; some research methods might be more appropriate than others. For example, clinical and laboratory experimental trials might receive better consummation if they use Quasi-experimental and Classical Experimental design rather than Cross Sectional Studies and Longitudinal Studies which focuses more on psychological experiments and behavior studies (Addison) (2015).

This study was limited due to the small sample size. Although the conclusions are valid, more research with a

Cross sectional designs involve studies of one group at one time and usually refer to a representative sample of this group. Longitudinal studies are studies of the same group over a period of time and generally are studies of change (Hagan, 2010, p. 83).Longitudinal design means the same subjects are observed multiple times in other words the researcher study the same variables over a preceding time, it is an observation done again several times in the same way. An advantage of longitudinal design is the ability to show a repeated or particular way in which something is done over time whereas the researcher can learn about the causation between actions such that one or more are the result of the other. The disadvantage of longitudinal design

Panel study is a type of longitudinal survey design in which the same people are examined over time. Data from a panel study enables researchers to identify and describe the types of changes or shifts that occur, if any, between the time periods and to examine factors that explain why some changes occurred and others did not.

These case studies examine each case individually to determine if the case used a randomized or non-randomized experiment followed by an explanation for the choice. In addition, each case will be studied to ascertain what design was used from the following list: within subject designs, factorial designs, between subject designs, time series design, interrupted time series design, and single case experimental research design. Next, each case will be reviewed to establish what threats to internal validity, if any, are present and explain the reasoning. Equally important in the example, was there a third variable problem and if so define the third variable problem in the specific case and finally did the case use longitudinal or cross-sectional

Quantitative data can take the form of either a cross-sectional design or a longitudinal design. Cross-sectional designs measure data at a specific point in time, while a longitudinal design involves collecting data at various intervals over a relatively extensive time period. This study is best suited towards a cross-sectional design method because of time constraints and the nature of our research. Longitudinal studies involve a greater time commitment than what is feasible for our study. Additionally, because our research does not involve an intervention, a longitudinal study is not necessary, as I am simply examining the relationship between two variables.

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

Research takes various designs, some of which are longitudinal in nature while others are case studies. Each study design has it various components that are followed and which distinguish it from the other (Menard, 2012). It should also be seen that each research design has its pros and cons and circumstances under which it can be used. In so doing, the researchers are supposed to pick on a research design that is likely to satisfy his goals to the maximum. Longitudinal research is supposed to take a long period, about ten years, for the objectives of this research to be achieved (Menard, 2012). It, therefore, means that very many resources have to be used in this research. This paper will take a look at one of these

Before listing the limitations of the original research design, I will briefly summarise the research question and methodologies.
