According to Graziano and Raulin (2007) there are two types of survey designs: Cross-sectional design is a survey which is conducted one time to a sample, resulting data on the measured features as they present at the point of the survey and Longitudinal survey designs is a survey which can be repeated to the same subjects at different times.
In a cross-sectional survey, research may be equated to a snapshot of the phenomenon of concern and data are collected at one point in time from a sample selected to describe an approximately greater population (Saris & Gallhofer, 2007). Such a survey can be used not only for the purpose of description, but also for determination of the relationship between variables at the time of the study (Babbie, 2010). In a longitudinal survey, data are collected from the same sample at several different times, with the main purpose being to study changes in the elements over time (McGivern, 2006). A Longitudinal study is inclined to being costly and fraught with great difficulties as a result of the relatively long periods of time it takes to conduct (Saris & Gallhofer, 2007). In fact, a longitudinal survey requires follow-up on respondents, which makes the capacity to capture a large sample size difficult if not, in certain

One of the main reasons for the selection of cross-sectional surveys is because of feasibility and practicality issues. Cross-sectional surveys are simple to design and establish research validity in addition to taking minimal time in the research project in comparison to longitudinal surveys. Furthermore, survey research can be conducted in different settings, it requires minimal investment to develop and administer, and it is relatively easy for making generalizations. It can also elicit information about attitudes that are otherwise difficult to measure using observational techniques (Rea & Parker,
1. What demographic variables were measured at the nominal level of measurement in the Oh et al. (2014) study? Provide a rationale for your answer.
The target respondents were invited to complete the questionnaire and directed them to a brief explanation of the research. If a respondent volunteered to participate they were able to read the instructions and complete the questionnaire online from any internet-connected device. Contact details of the researcher were also provided in the initial description of the form should the respondent have any enquiry regarding the questionnaire. Data were collected on 23rd December 2015 from 8 a.m. until 8 a.am 24th December 2015. The length of time for data collection was considered ideal as it allowed a sufficient amount of time for interested respondent to participate in the study.
Paul, Thanks you so much. I will spend today and part of tomorrow to rewrite the abstract to make more stronger substantial contribution to theory (Descriptive Theory) and practice of research ( Mixed Method - Qualitative Driven and Quantitative Supplementary Component Cross National Comparative). I will try and phone you if that is okay. Thanks again Regards
The study was longitudinal so that efficient data would be acquired. Thirty-five
I will choose observational retrospective cohort design for my study. My research question was to identify the association between socioeconomic, biopsychosocial, environmental and genetic factors, and the development of childhood asthma. To establish the effect of allergen (cockroaches, dust), poverty, poor air ventilation in a house, racial factors and air pollution on developing children asthma, a cohort have to have a exposure and the cohort need to followed over time. Cohort studies are used to study the incidence, causes, natural history of a disease and prognosis.1 Because they measure events in the chronological order, they can be used to distinguish between cause and effect.1 This type of study is the best method for determining the incidence and natural history of a disease or condition.1 One of the advantages of doing retrospective cohort study is that the data already collected for some other research study or purposes. The cohort is “followed up” retrospectively.1
national study conducted at a south western university. The respondents were selected from those who registered in an online panel by the AS Nielsen. For the possible distribution of the demographics variables, they gathered the gender, age, education and income of the sample reported by the U.S. Census. It was conducted in December 2013 and January 2014. The researchers administered a survey through Qualtrics, an online survey software.
Having the research be longitudinal is also really good when it comes to presenting the effectiveness of Head Start REDI program. I wonder why they chose to end the study at third grade instead of continuing it up until they leave elementary school. The researchers provided a lot of information about the Head Start REDI program and how it was more a benefit for kids who live in poverty. A weakness that I found is that it was hard for me to read the data. Typically, a research paper should be at a 5th grade reading level but, I often found myself lost in the paragraphs and unable to understand how the data was measured.

There have been two significant pushes for school improvement during the second half of the 20th Century. One, Sputnik in 1957, and the other was the publication of A Nation at Risk in 1983. Both events exposed the ranking of the United States compared to other countries. How do we provide more enrichment without extending the school day? Homework.

1.3 Explain the impact of adolescent development on a young persons thoughts, feelings and behaviours. During puberty the body will go through many changes and a young person will start to become more aware of their body and their personal appearance. As they go through these changes a young person will also try to find their identity but still want to fit in with their peers which may have an influence on their likes and dislikes. They will also become more sensitive to their feelings being highly emotional/upset or easily frustrated over minor issues. These emotional changes also cause mood swings resulting in young people becoming irritable or moody at times and not wanting to converse, this is also due to the hormonal changes
In addition, using longitudinal studies follows the young person’s life through a 3-10 months’ time frame and allows the researcher to experience their participation in the care system. For
In the future, should I choose to further my research, I will send out a more detailed questionnaire that breaks down responders by gender, education, income, marital status, and more. I will also disperse it further into the community to ensure that the sample population is more
Late Adulthood is the stage of the human life cycle where an individual nears the end of their life. The life expectancy in the United States has slowly increased over the years therefore allowed many to further analyze the physical, cognitive, and psychosocial development during late adulthood. The stage of late adulthood has been emphasized by ageism and the stereotypical "old" person but, will be further educated by the normative development of the life cycle of late adulthood. For the “old” experience dramatic changes in their development as they face loss, death, and illness.
My Self-Concept My self-concept includes a number of different adjectives and roles, these include both good and bad things. The adjectives I use to describe myself are as follows: kind, loyal, selfish, hard working, apathetic, practical, honest, occasionally rude, and procrastinator. As for the roles that I fill, I am a son, a brother, a friend, a student, the oldest son, and a teacher. Self-concept is a product of many things, it is not just simply what a person is.
