rs statistics Flashcards
Whats quantitative data
*data that is expressed numerically
*data can be gained from individual scores in experiments
Strengths of using quantitative data
*simpler to analyse
*allows comparisons to be drawn between groups of data
*patterns and trends can be established
Weakness of using quantitative data
*lacks depth and meaning to beahviour
*prevents ppts from being able to develop their thoughts/feelings and opinions
*lack vital data and reduces the internal validity
Strengths of qualitative data
*provide rich detail and depth
*allows ppts to develop their thoughts and feelings on given subject
*greater understanding of behaviour being studied
Whats qualitative data
*data expressed in words
*may take the form a written description of thoughts, feelings and opinions usch as notes from interview or open questions in questionnare.
Weaknesses of qualitative data
*harder to analyse as difficult to summarise statistically to establish patterns and trends
*opens data to potential researcher bias as analysis in based upon their subjective interpretations of data
What are the diffrent types of quantitative data
*Nominal
*Ordinal
*Interval
Describe nominal data
*data in the form of categories
Describe ordinal data
*ordered/ranked
*doesnt have fixed intervals
*data based on subjective opinions
Whats a weakness of ordinal data
*seen as unsafe as it lacks precision and not used part of statistical testing
Describe interval data
*data is standardised/universal measurement
*based on objectiv emeausres like time in seconds
*based on numerical scales that include units of equal size
Whats primary data
*data gathered directly from ppts themselves
*specific to the aim of the study
How can primary data be gathered?
*experiments
*questionnares
*interview
*observations
Strengths of primary data
*collected first hand from ppts spcifically for thr aim
*allows researchers to specifically target the info that they need
*organise experiment in a way that suits them and their aim
Weaknesses of primary data
*conducted by the researcher
*involves time and effort to obtrain the data
