For the following studies, identify the possible target population, elementary unit, sampling frame, sampled population and sampling unit.
1. A doctor wishes to study people working at a hotel in Makati afflicted with hypertension.
2. A researcher would like to estimate the average monthly electricity consumption of households in Quezon City.
Sure! Let's break down each study and identify the possible target population, elementary unit, sampling frame, sampled population, and sampling unit.
1. Study: A doctor wishes to study people working at a hotel in Makati afflicted with hypertension.
- Target population: The target population in this study would be all individuals who work at hotels in Makati.
- Elementary unit: The elementary unit would be individual employees of the hotel.
- Sampling frame: The sampling frame would be a list of all hotels in Makati.
- Sampled population: The sampled population would be all hotel employees with hypertension.
- Sampling unit: The sampling unit would be individual hotel employees who have been diagnosed with hypertension.
To get this information, the doctor would need to obtain a list of all hotels in Makati (sampling frame) and then select a sample of hotel employees (sampling unit), checking their medical records to identify those with hypertension (sampled population).
2. Study: A researcher would like to estimate the average monthly electricity consumption of households in Quezon City.
- Target population: The target population in this study would be all households in Quezon City.
- Elementary unit: The elementary unit would be individual households.
- Sampling frame: The sampling frame would be a list of all households in Quezon City.
- Sampled population: The sampled population would be households in Quezon City.
- Sampling unit: The sampling unit would be individual households.
To estimate the average monthly electricity consumption, the researcher would need a list of all households in Quezon City (sampling frame). Then, they could select a sample of households (sampling unit) and collect data on their monthly electricity consumption (sampled population) to calculate the average.
