Types of sampling
What is sampling? Define simple random sampling and stratified random sampling with some relevant examples. [5]
When one-by-one study of all units of a population is not possible due to factors like time, cost, manpower, resources, and destructive nature of study, we take a small representative part from the population for study. This small representative part select...
Full solved answer →What do you understand by sampling? Differentiate between a simple random variable and stratified random sampling. [5]
Sampling is the process of selecting a subset of units (called a sample) from a larger group (called the population) in order to draw conclusions or make inferences about the entire population. Since studying every unit in a population is often impractical ...
Full solved answer →What do you mean by sampling? Explain the difference between stratified sampling and cluster sampling. [5]
Sampling is the process of selecting a subset of individuals (called a sample) from a larger group (called the population) in order to draw conclusions or make inferences about the entire population. Since it is often impractical or impossible to study ever...
Full solved answer →What is sampling? Discuss various probability sampling techniques with merits and demerits. [5]
When one-by-one study of all units of a population is not possible due to factors like time, cost, manpower, resources, and destructive nature of study, we take a small representative part from the population for study. This small representative part select...
Full solved answer →What do you mean by sampling? Explain non probability sampling with merits and demerits. [5]
When one-by-one study of all units of a population is not possible due to factors like time, cost, manpower, resources, and destructive nature of study, we take a small representative part from the population for study. This small representative part select...
Full solved answer →What is sampling? Explain the main purpose of sampling. Describe briefly stratified sampling. [5]
--- Sampling is the process of selecting a subset (called a sample) of units from a larger group (called the population) in order to draw conclusions or make inferences about the entire population. Instead of studying every unit in the population (census), ...
