Stratification is the process of dividing members of the population into homogeneous subgroups before sampling. The strata should define a partition of the population. That is, it should ‘Strata’ is a characteristic of stratified sampling method in which the entire population is divided into several homogeneous groups and a simple random sampling technique is applied on each of these groups. Such homogeneous groups are called as Strata.

A stratum in statistics isn’t much different — you can think of it as where your target population is divided into non-overlapping layers, subgroups, or categories. For example, strata could define the socioeconomic statuses of a population: Stratified random sampling is a method of sampling that involves dividing a population into smaller groups–called strata. The groups or strata are organized based on the shared characteristics or In statistics, stratified randomization is a method of sampling which first stratifies the whole study population into subgroups with same attributes or characteristics, known as strata, then followed by simple random sampling from the stratified groups, where each element within the same subgroup are selected unbiasedly during any stage of the sampling process, randomly and entirely by chance.

In statistics: Sample survey methods. Stratified simple random sampling is a variation of simple random sampling in which the population is partitioned into relatively homogeneous groups called strata and a simple random sample is selected from each stratum. The results from the strata are then aggregated to make inferences about… Read More strata and that maximize variation among strata. Stratified random sampling is appropriate whenever there is heterogeneity in a population that can be classified with ancillary information; the more distinct the strata, the higher the gains in precision. The same population can be stratified multiple times simultaneously.

The results from the strata are then aggregated to make inferences about the population. A T-test is a hypothesis test with a t-distribution that uses a t-statistic. You would use a t-test when you don’t know the population variance and have a small sample size. You also need the degrees of freedom to convert a t-statistic to a p-value.

Sometimes the sum is weighted by stratum totals, sometimes strata are equally weighted. (I believe that SAS does the former; Rothman gives the formula for the latter.) Statistical errors are the deviations of the observed values of the dependent variable from their true or expected values.
