- Q6What is the formula for calculating the probability of an event?Number of favorable outcomes / Total number of outcomesNumber of favorable outcomes + Total number of outcomesNumber of favorable outcomes * Total number of outcomesTotal number of outcomes - Number of favorable outcomes30s
- Q7What is a simple random sampling?Selecting a random sample in such a way that each member of the population has an equal chance of being chosenSelecting a sample where each member of the population knows each otherSelecting a sample based on convenienceSelecting a sample where the researcher knows each member of the population30s
- Q8What is stratified sampling?Selecting a sample based on convenienceSelecting a sample where the researcher knows each member of the populationDividing the population into subgroups (strata) and randomly selecting samples from each stratumSelecting a sample where each member of the population knows each other30s
- Q9What is cluster sampling?Selecting a sample where the researcher knows each member of the populationDividing the population into clusters and randomly selecting entire clusters as samplesSelecting a sample where each member of the population knows each otherSelecting a sample based on convenience30s
- Q10What is convenience sampling?Selecting a sample based on ease of access or availabilitySelecting a sample where each member of the population knows each otherSelecting a sample based on specific characteristicsSelecting a sample using random number generation30s
- Q11What is systematic sampling?Selecting a sample where the researcher knows each member of the populationSelecting every nth individual from the populationSelecting a sample based on convenienceSelecting a sample where each member of the population knows each other30s
- Q12What is non-probability sampling?Selecting a sample where each member of the population knows each otherSelecting a sample where the researcher knows each member of the populationSelecting a sample based on convenienceSelecting a sample without giving every member of the population an equal chance of being chosen30s
