For instance, if estimating the effect of a drug on blood pressure with a 95% confidence interval that is six units wide, and the known standard deviation of blood pressure in the population is 15, the required sample size would be =, which would be rounded up to 97, since sample sizes must be integers and must meet or exceed the calculated ...
Bias in standard deviation for autocorrelated data. The figure shows the ratio of the estimated standard deviation to its known value (which can be calculated analytically for this digital filter), for several settings of α as a function of sample size n. Changing α alters the variance reduction ratio of the filter, which is known to be
Current Sociology is a bimonthly peer-reviewed academic journal covering the field of sociology. Established in 1952, it is an official journal of the International Sociological Association [ 1 ] and published on their behalf by SAGE Publications .

Level of analysis is used in the social sciences to point to the location, size, or scale of a research target. It is distinct from unit of observation in that the former refers to a more or less integrated set of relationships while the latter refers to the distinct unit from which data have been or will be gathered.
According to the Journal Citation Reports, the journal has a 2015 impact factor of 1.926, ranking it 56th out of 344 journals in the category "Economics", 21st out of 163 journals in the category "Political Science" and 19th out of 142 journals in the category "Sociology".
When only a sample of data from a population is available, the term standard deviation of the sample or sample standard deviation can refer to either the above-mentioned quantity as applied to those data, or to a modified quantity that is an unbiased estimate of the population standard deviation (the standard deviation of the entire population).
