Sampling Methods and Their Justifications

The video tutorial discusses various sampling methods, including random, stratified, and systematic sampling. It explains the importance of choosing the right method based on the scenario and uses tools as metaphors to illustrate different sampling techniques. The tutorial emphasizes the need to justify the choice of sampling method and provides guidance on selecting the most suitable one for different situations.

What is the main focus of stratified sampling?

• Ensuring equal sample sizes

• Maintaining proportional representation

• Selecting every nth individual

• Randomly selecting individuals

Why might systematic sampling be preferred over random sampling in certain situations?

• It requires fewer resources

• It is more random

• It is easier to implement

• It ensures regular intervals

Which sampling method ensures that samples are taken at regular intervals?

• Random sampling

• Systematic sampling

• Stratified sampling

• Cluster sampling

How are different sampling methods compared to tools in the video?

• They are interchangeable

• They solve different problems

• They are all used for the same purpose

• They are chosen based on the scenario

What is the key factor in choosing the right tool or sampling method?

• The popularity of the tool

• The scenario in which it is used

• The availability of the tool

• The cost of the tool

What is the metaphor used to explain the selection of sampling methods?

• Finding the correct path

• Picking the best fruit

• Selecting the right tool

• Choosing the right vehicle

What should be considered when evaluating scenarios for sampling?

• The ease of implementation

• The justification for the choice

• The speed of data collection

• The number of samples needed

Why is justification important when choosing a sampling method?

• It helps in understanding the method

• It ensures the method is cost-effective

• It validates the choice made

• It simplifies the process

What is the main challenge when selecting a sampling method for a scenario?

• Ensuring the method is popular

• Determining the most suitable method

• Finding the cheapest method

• Choosing the fastest method

What is the primary goal when using different sampling methods?

• To solve similar problems

• To collect data quickly

• To use the most advanced method

• To minimize costs
