Quantitative Research Flashcards
what are official statistics
numerical data collected by the government through agencies such as the ONS and the census survey
what are unofficial statistics
numerical data collected by non government bodies
what are some examples of government surveys that are used to collect statistics
the general household survey and the labour force survey, which provide data on income, wealth, jobs, family life, poverty, etc.
why could the ONS be argued as a reliable source of statistics
it provides information for the government, and can be scrutinised and held accountable for the data it collects. it collects data in the national interest and therefore should be free from any biases of private research
what are some issues with the ONS
it has been argued by some sociologists to lack validity as the government can often massage data to make things look better than they actually are.
why are official statistics reliable
they can be checked by journalists who can put in a freedom of information request so that they can be scrutinised properly/
what are the strengths of official statistics
they are easy to access, up to date, often use large representative samples, and it is easy to see trends over time.
what are the weaknesses of official statistics
their reliability is wavered slightly due to the differing definitions there are. the government could collect data on unemployed but their criteria for what is unemployed may differ to that of the views of the sociologist who uses the data, which can lead to a misrepresentation of the data. they are also partial to political abuse and are socially constructed.
what are surveys
surveys are a systemic collection of mainly qualitiative data from a large number of people.
what is an example of a survey
the british household panel survey. a longitudinal survey based uopn periodic interviews and questionnaires which provides data on various aspects of social change in british families.
what are longitudinal studies
these are studies that study the same group of people over a long period of time
what are the benefits of longitudinal studies
they provide us with information on changes in attitudes and behaviours over a number of years
what are the weaknesses of longitudinal studies
the respondents may drop out, or the researchers may lose track of them, which undermines the representativeness of the original sample. there is danger that the research team may get too friendly with the group. the people being studied are aware they are being studied which can have an impact on the choices they make
what is the problem with using studies that extended over a short period of time
the study cannot fully show the developments, and so the results can be misleading
what is the problem with using retrospective studies
these rely on people’s memories, which are not reliable because things can be forgotten or manipulated
what is a questionnaire survey
these are lists of questions written down in advance that people answer. they use a variety of different question types, as you can get closed questionnaires with tick the box answers, and you can also get the open questioned ones where the respondents use their own words
what needs to be considered when preparing a questionnaire
that they are straightforward - most people dont have the patience to sit and answer 100 open end questions. the questions should be neutral and objective; dont sway the respondents viewpoints. dont use vague words as they mean different things to different people.
what are the strengths of questionnaires
they can reach more people and are easy to distribute to the respondents. they are less time and money consuming than other methods. provide anonymity, so people are more honest about the more sensitive topics such as sexual behaviour. ensures minimal contact between researcher and respondent.
what are the weaknesses of questionnaires
they can be designed poorly, with vague wording or complex wording that the respondents dont fully understand. many people cannot be bothered to reply to them either
what are academic studies
these are studies carried out by universities led by at least one expert academic and researched by teams of skilled researchers.
why are academic studies reliable
they are peer reviewed by other academics in the field who will point out any inconsistencies and problems
what is an example of an academic study that failed
a medical study in 1998 falsely linked the MMR vaccine to autism, resulting in many parents choosing not to have their children vaccinated, leading to an anti-vaxxer movement.
what should be considered when thinking of using an academic study
what methods were used in the study, are they biased according to the researchers, who is paying for the research
what does the reliability of tv news depend on
the company producing the news, and the ability to check facts against other sources
