AP Statistics Sample Survey Analysis

AP Statistics Sample Survey

The AP Statistics sample survey is a comprehensive analysis of the relationship between participation in Advanced Placement (AP) Statistics and subsequent college-level statistics. The survey aimed to gather information on the rationale behind taking AP Statistics, the impact of the course material on interests, and the likelihood of pursuing statistics further.

Sampling Methods

The AP Statistics sample survey utilized a variety of sampling methods to ensure a diverse representation of participants. The sample was drawn from AP Statistics exam-takers during the years 1997 to 2003, with a response rate of approximately 19% after adjusting for delivery failures and refusals. The final sample consisted of 2,143 examinees out of the nearly 230,000 potential subjects.

Random Sampling

Random sampling was employed as a foundational principle in the construction of the sample. Every member of the target population had an equal opportunity to be selected into the sample, ensuring a balanced representation across various demographic characteristics, including gender, exam score, and geographical location.

Stratified Sampling

In addition to random sampling, stratified sampling was also applied to address concerns regarding sample selection probabilities. This approach involves dividing the population into homogeneous strata based on predefined criteria (such as year of examination, exam grade, gender, or U.S. regions). Within each stratum, a simple random sample was taken, resulting in a more robust estimation of population parameters across different groups within the population. This method helped account for the possibility of differential response rates across strata, allowing for a more precise evaluation of the relationship between AP Statistics participation and subsequent college-level statistics.
