SOC202H1 Chapter Notes -Statistical Inference, Standard Deviation, Raw Score
Document Summary
Ch5 measuring dispresions or spread in a distribution of scores. Dispersion how the scores of an interval/ratio variable are spread out form the lowest to highest and the shape of the distribution inbtwn: infinite possible distribution shapes for a variable w/ a given mean. The standard deviation as an integral part of inferential statistics. Standard deviation & mean useful for getting sense of proportions of. Spread may vary btwn populations individual variables under study: dispersion statistics statistics that describe how the scores of an. Inferential statistics: interest w/ understanding why individual scores of a interval/ratio variable are spread across its distribution dependent variable deviate from its mean. The range an expression of how the scores of an interval/ratio variable are distributed from lowest to highest. The distance btwn min. and max. scores found in a sample. Range = (max score min score) + value of rounding unit. Very susceptible to outliers, more so than mean: 2.
