SOC 8311 Basic Social Statistics
... MSERROR, as revealed by the F test statistic. An F statistic to test a null hypothesis is a ratio two Mean Squares. Each MSs has a different degrees of freedom (df = 1 in the numerator, df = N-2 in the denominator). For large samples, use this table of critical values for the three conventional ...

Inference for Proportions
... The TI-83 Plus and TI-84 Plus calculate the confidence interval for the difference of two proportions with the command 2-PropZInt. You find this command by pressing Ö, arrowing over to TESTS, and selecting B:2-PropZInt. At the prompts, enter the number of successes in each sample, x1 and x2, both sa ...

Tests for Paired Means
... Usually, a researcher designs a study to compare two or more groups of subjects, so the one sample case described in this chapter occurs infrequently. However, there is a popular research design that does lead to the single mean test: paired observations. For example, suppose researchers want to stu ...

We infer the population parameter from the sample statistic. Some population parameters cannot be inferred from the statistic. The population size N cannot b ...
