(2) Statistical process sampling and experimentation. The student applies mathematical processes to apply understandings about statistical studies, surveys, and experiments to design and conduct a study and use graphical, numerical, and analytical techniques to communicate the results of the study. The student is expected to:

• (A) compare and contrast the benefits of different sampling techniques, including random sampling and convenience sampling methods;

• (B) distinguish among observational studies, surveys, and experiments;

• (C) analyze generalizations made from observational studies, surveys, and experiments;

• (D) distinguish between sample statistics and population parameters;

• (E) formulate a meaningful question, determine the data needed to answer the question, gather the appropriate data,analyze the data, and draw reasonable conclusions;

• (F) communicate methods used, analyses conducted, and conclusions drawn for a data-analysis project through the use of one or more of the following: a written report, a visual display, an oral report, or a multi-media presentation; and

• (G) critically analyze published findings for appropriateness of study design implemented, sampling methods used, or the statistics applied.
