SOC202H1 Lecture Notes - Sampling Distribution, Standard Error
Document Summary
How much variation do you have from sample to sample. Calculate standard deviation; little consensus if there is a large sd. Less spread around the mean = smaller sd = more consensus. Large standard error = less reliability in sample. Standard deviation is numerator for formula of standard error. Denominator is sample size larger denominator = better because it spreads out more; therefore a decreases standard error. Sampling distribution of means: taking samples over and over again and plotting the means. Large error term: large sample to sample variability and wide confidence intervals. *analytical thinking exercises: standard error would increase; greater sample to sample variability. Value of upper critical limit would increase and value of lower critical limit would decrease: standard error stays the same (does not depend on ci) Value of upper critical limit would increase and value of lower critical limit would decrease. 1. 96 = 95% ci: standard error increases.
