Exam 14: Understanding and Using Standardized Tests
In 1936, two separate surveys were administered to predict the results of the presidential election. The survey that was administered to over 2 million people was incorrect whereas a much smaller survey came up with the correct prediction. Discuss this outcome with respect to sampling procedures.
The outcome of the 1936 presidential election surveys highlights the importance of sampling procedures in obtaining accurate predictions. The larger survey, which was administered to over 2 million people, was incorrect in its prediction. This could be attributed to the sampling procedure used, which may have been biased or not representative of the entire population. It is possible that the sample was not diverse enough or did not accurately reflect the demographics and opinions of the entire voting population.
On the other hand, the much smaller survey that came up with the correct prediction likely used a more rigorous and representative sampling procedure. This smaller survey may have employed random sampling or stratified sampling to ensure that the sample accurately represented the population as a whole.
This outcome underscores the importance of using sound sampling procedures in survey research. A larger sample size does not necessarily guarantee accuracy if the sampling procedure is flawed. It is crucial to use methods that ensure the sample is representative of the entire population in order to obtain reliable and accurate predictions.
After determining the primary purpose of the survey, the researcher must:
A
