The Aim of Sociological Research To move from subjective to more objective knowledge of something: Subjective knowledge An individual’s everyday understanding that comes from their values, experiences and beliefs. Objective knowledge Knowledge that is independent of opinion, prejudice and bias. © onlineclassroom.tv 2007

Three key research criteria: Reliability. Validity. Representativeness. © onlineclassroom.tv 2007

Reliability concerns:  Consistency of the data collected.  The precision with which it is collected. Data is reliable if the same results can be gained by different researchers asking the same questions to the same (or similar) people.  The repeatability of the data collection method. A method is more reliable if it can be easily repeated. © onlineclassroom.tv 2007

Valid data involves: Validity: the extent to which the collected research data represents what it claims to represent.  Depth.  Detail.  A well-rounded picture of whatever is being researched. © onlineclassroom.tv 2007

Representativeness: whether the results of research can be generalised to wider populations.  Demographic data is representative if the information collected is comprehensive.  Sampling is representative if the characteristics of the sample group reflect the characteristics of the target population.  Case studies can be representative if they are a typical of the group or institution being researched. © onlineclassroom.tv 2007

Sample: a segment of the target population being studied.  Simple Random  Systematic  Stratified Probability [reflects the population] Non-Probability [does not reflect the population]  Opportunity  Snowball  Cluster / Multistage © onlineclassroom.tv 2007

Objective understanding involves a search for: May have to make do with less validity Reliability May have to sacrifice reliability Validity Can’t always construct a representative sample Representativeness © onlineclassroom.tv 2007
