Sample Size Quiz

What is the purpose of determining the sample size in a research study?

• To include the whole population in the study

• To make the study more complex and time-consuming

• To reduce the cost of running the study

• To get accurate and statistically significant results

What does the term 'sample size' refer to in statistics and market research?

• The size of the entire population being surveyed

• The confidence level of the study

• The number of individuals included in the study

• The margin of error in the study

What is the purpose of using a confidence level in determining the sample size?

• To increase the margin of error

• To decrease the margin of error

• To determine the probability that the actual mean falls within the margin of error

• To make the study more complex

What is the formula used to calculate the sample size for continuous or actual data?

• Glenn's formula

• Yamane's formula

• Slovin’s formula

• Chan Shio & Reyes formula

What is the purpose of including the whole population in a study if the population size is 100 or less?

• To increase the margin of error

• To simplify the study

• To reduce the cost of the study

• To make the study more accurate

What is the purpose of using a margin of error in determining the sample size?

• To increase the confidence level

• To decrease the confidence level

• To express the level of error in terms of mean numbers

What is the purpose of using the probability value or alpha level in determining the sample size?

• To decrease the margin of error

• To increase the margin of error

• To express the level of error in terms of mean numbers

• To make the study more complex

What is the purpose of rounding the calculated sample size to a whole number?

• To increase the margin of error

• To make the study more accurate

• To simplify the calculation

• To avoid sampling a fraction of a person or thing
