A cognitive psychologist is interested in comparing two ways of presenting stimuli on subsequent memory. Twelve subjects are presented with each method and a memory test is given. What would be the roles of descriptive and inferential statistics in the analysis of these data

Answer:The descriptive statistics will give the summary in words of all 12 subjects presented with each method. And Inferential Statistics is will give the result concluded by 12 subjects presented with each method. In Descriptive Statistics we are most often interested in the summary of data in words. It is done by describing the features of the data. Mostly we explain the five-number summary of the data, central tendency of data, dispersion, skewness, etc. Overall we summarize the quantitative data in words.Whereas, Inferential Statistics will take a random sample from the population and using these sample it tells the characteristics of population.
