Determine whether the following statement is true or false. Explain. When obtaining a stratified sample, the number of individuals included within each stratum must be equal. Choose the correct answer below. $\bigcirc$ A. True, because if there is a stratum with more or less individuals, it will be weighted more or less than the other strata. This will introduce bias. $\oplus$ B. False, because as long as each stratum has a threshold number of individuals representative of the variation in the population, results are meaningful. The number of individuals does not need to be exactly equal. $\bigcirc$ C. True, because if some strata have significantly less individuals than others, there can be no meaningful results from them. $\bigcirc$ D. False. The individuals in each stratum must be homogenous.
