Do you think a study conducted on a small number of individuals stands true for a population as a whole? Justify your answer.
Answers
Answer :
A study conducted on a small number of individuals may not be representative of the population as a whole because a small sample size may not have enough diversity and power to detect true differences or relationships, and the generalizability of the study depends on the sampling method used.
Explanation :
A study conducted on a small number of individuals, also known as a small sample size, may not necessarily be representative of the population as a whole. This is because a small sample size may not have enough diversity in terms of characteristics such as age, gender, race, socioeconomic status, and other factors that can affect the results of the study. Additionally, a small sample size may not have enough power to detect true differences or relationships between variables, leading to false conclusions.
It's important to keep in mind that as the sample size increases, the study becomes more likely to be representative of the population as a whole. However, even with a large sample size, the study's generalizability to the population depends on the sampling method used. A study that uses a random sampling method is more likely to be representative of the population as a whole compared to a study that uses a non-random sampling method.
Therefore, it is important to consider the sample size and sampling method when interpreting the results of a study. A study conducted on a small number of individuals may have limitations and should be interpreted with caution when generalizing to the population as a whole.
