Sampling Techniques and Data-gathering Procedures

The process of choosing a representative portion of the population is called ________.

• Methodology

• Sampling

• Experimenting

• Choosong

A (a)   is a finite portion of a population that will be used or investigated in the study.

Probability sampling method is also known as (a)   sampling method.

What is the type of sampling method which is entirely biased and hence the results are biased too, rendering the research speculative?

• Experimental

• Quantitative

• Qualitative

• Non-probalbility

In an organization of 500 employees, if the HR team decides to conduct team-building activities, they would likely prefer picking chits out of a bowl. In this case, each of the 500 employees has an equal opportunity of being selected. What type of probability sampling method is this?

• Cluster Sampling

• Systematic Sampling

• Simple Random Sampling

• Stratified Sampling

A researcher intends to collect a systematic sample of 500 people in a population of 5000. He/she numbers each element of the population from 1-5000 and will choose every 10th individual to be a part of the sample (Total population/Sample Size = 5000/500 = 10). What type of probability sampling is this?

• Stratified Sampling

• Systematic Sampling

• Simple Random Sampling

• Cluster Sampling

Suppose the Philippine government wishes to evaluate the number of foreigners living in Metro Manila. In that case, they can divide it into clusters based on cities such as Quezon City, Makati City, Pasig City, Mandaluyong City, Taguig City, Caloocan City, etc. This way of conducting a survey will be more effective as the results will be organized into cities and provide insightful foreign data. What type of probability sampling method is this?

• Cluster Sampling

• Stratified Sampling

• Simple Random Sampling

• Systematic Sampling

A researcher looking to analyze the characteristics of people belonging to different annual income divisions will create strata (groups) according to the annual family income. E.g. – less than 20,000, 21,000 to 30,000, 31,000 to 40,000, 41,000 to 50,000, etc. By doing this, the researcher concludes the characteristics of people belonging to different income groups. Marketers can analyze which income groups to target and which ones to eliminate to create a roadmap that would bear fruitful results. What type of probability sampling method is this?

• Cluster Sampling

• Simple Random Sampling

• Stratified Sampling

• Systematic Sampling

Sampling is done due to limitations of time, money, or personnel.

• True

• False

Many errors are encountered in the collection and handling of data is sampling is done.

• True

• False
