Data Interpretation and Probability
Data Interpretation and Probability Students will compare various methods of reporting data to make inferences or predictions.
Students will select and use appropriate statistical methods to analyze data.
This task allows students to analyze data sets that they might typically collect to set up scatter plots. Students then determine linear trends and lines of good fit when they exist.
Statistics is a new emphasis in most secondary mathematics programs. Among those programs that cover statistics, many tend to focus primarily on data analysis. This task goes beyond analyzing data by connecting the various discrete steps involved in designing and conducting a study. The task allows students to see the big picture of statistical studies and the various steps involved in undertaking such a study: identifying a question; determining how and from where or whom to gather data; conducting the study; gathering, organizing, and displaying the data; and analyzing and reporting results in response to the question.
Students (and adults) often confuse probability and odds, and misuses of these terms are common in the media. This task allows a discussion of the difference between and the relationship between these two concepts using interesting contexts found in the media.
