What is obtained by dividing the population into groups and selecting all individuals from within a random sample of the groups?
This method is known as cluster sampling. In cluster sampling, the entire population is divided into clusters, often based on geographical areas or other natural groupings. Then, a random selection of these clusters is made, and all individuals within the selected clusters are included in the sample. This approach can be more practical and cost-effective than other sampling methods, especially when the population is large and dispersed.

Which sample is obtained by dividing the population into homogeneous groups and randomly selecting individuals from each group?
The sample obtained by dividing the population into homogeneous groups and randomly selecting individuals from each group is known as a stratified random sample. This sampling method ensures that different subgroups within the population are adequately represented, enhancing the precision of the estimates for the overall population. By focusing on specific strata, researchers can better analyze variations and characteristics within each group.
How does dividing a number by a fraction involve multiplication?
When dividing by a fraction, the answer is obtained by multiplying by the reciprocal.
What is the number obtained by adding up the data for a given characteristic and dividing this sum by the number of individuals?
The number obtained by adding up the data for a given characteristic and dividing this sum by the number of individuals is called the mean or average. It represents a central value that summarizes the data set, providing insight into the overall trend of the characteristic being measured. This calculation is commonly used in statistics to analyze and interpret data.

Which sampling is obtained by dividing the population into groups and selecting all individuals from within a random sample of the groups?
It is called one-stage cluster sampling. If random samples are taken within the selected clusters then it is two-stage cluster sampling.
