What is the primary purpose of sampling?
To increase the sample size
To analyze the entire population
To get a representative portion of a population
To eliminate bias in research
Which of the following is NOT an advantage of sampling?
Requires a larger population
More effective data collection
Saves time and money
More comprehensive information
What is a disadvantage of sampling?
It requires less effort
Results may be misleading if not designed correctly
It is faster than studying the entire population
It is always accurate
When is sampling advisable according to the text?
When the population is less than 50
When the population is equal to or more than 100
When the population is exactly 100
When the population is less than 100
What does the formula for determining sample size include?
Only the population size
Only the standard value
Population size and sampling error
Only the sample size
What is Restricted Random Sampling?
A method with high potential for bias
A method that uses only one stratum
A compromise between systematic and stratified sampling
A method that requires no planning
What is a characteristic of Stratified Random Sampling?
It reduces the cost of collecting data
It selects individuals randomly from the entire population
It separates the population into overlapping groups
It is less accurate than Simple Random Sampling
What is the main feature of Systematic Sampling?
Dividing the population into clusters
Choosing members at regular intervals
Selecting members at random from the population
Using only one sampling unit
What does Purposive Sampling involve?
Selecting samples randomly
Sampling the entire population
Using a fixed number of samples
Choosing samples based on their unique position
What is Incidental Sampling?
Sampling based on specific criteria
Sampling from a predetermined list
Taking samples that are most available
Using random selection methods
What is the purpose of QOOTA SAMPLING?
To randomly select individuals from the population
To segment the population into mutually exclusive sub-groups
To ensure equal representation of all groups
To eliminate bias in sampling
What is a key feature of Cluster Sampling?
It requires a large sample size
It is a non-probability sampling method
The entire population is divided into groups
All observations in selected clusters are excluded
What is the main focus of Non-Scientific Sampling?
To use statistical methods
To minimize sampling error
To achieve specific research goals
To ensure random selection
What does the term 'population' refer to in sampling?
A small group of individuals
The total of objects, persons, or species
Only the individuals being studied
A random selection of samples
What is the significance of the standard value (2.58) in the sample size formula?
It is the maximum sample size
It indicates the level of reliability
It represents the total population
It is the minimum sample size
