Document Summary
Estimation of the standard of the standard error. Computation of the t statistic usin the estimates standard error. Estimated standard error of m: approximation of the standard distance between a sample mean and the population mean. T statistsic: hypothesis testin tool in which estimates standard error is sued in the z score formula denominator. Degree of freedom: figure in a sample that is independent and can vary. T distribution: complete set of t values computed for every possible random sample for a sample size. Estimated cohens d: fiure calculated when substituting sample values in place of population values. Calculation of the sample variance as a asubstitue for the unknown population value. Percentage of variance account for by the treatment. Measurement of reduction in variability after removing the treatment effect.
