Swollen tonsils that are not painful or do not cause other problems do not need to be treated. Your provider may not give you antibiotics. You may be asked to come back for a checkup later. If tests show you do have strep, your doctor will give you antibiotics.
Stratified Random Sampling. Stratified random sampling is a probabilistic sampling option. The first step in stratified random sampling is to split the population into strata, i.e. sections or segments. The strata are chosen to divide a population into important categories relevant to the research interest.
With Stratified random sampling the population is divided into mutually exclusive small subgroups (strata), e.g. males and females. The members, for the sample, are then selected from each group.ith Stratified random sampling the population is divided into mutually exclusive small subgroups (strata), e.g. males and females.
