About me

Statistics: This is the quantitative data on any subject, usually collected with a purpose such as recording performance of bodies for comparison, or for public record and which can then be analyzed by a variety of statistical methods.

 

AP Statistics: The AP Statistics exam is divided into multiple choice questions and free response.  Lessons review exploring data (describing patterns and departures from patterns), sampling and experimentation (planning and conducting a study), anticipating patterns (exploring random phenomena using probability and simulation),  Exploring data includes constructing and interpreting graphical displays of distributions of univariate data (dotplot, stemplot, histogram, cumulative frequency plot). Summarizing distributions of univariate data includes measuring center – mean and median, measuring spread – range, interquartile range, standard deviation, measuring position – quartiles, percentiles, standardized scores (z-scores), using boxplots, and the effects of changing units on summary statistics.  Exploring bivariate data includes analyzing patterns in scatterplots, correlation and linearity, least-squares regression line, residual plots, outliers, and influential points. Sampling involves an overview of methods of data collection (i.e., census, sample survey, experiment, observational study); planning and conducting surveys (what are surveys, populations, samples, and random selection; sources of bias in samples and surveys); planning and conducting experiments (treatments, control groups, experimental units, random assignments, and replication; sources of bias and confounding).  Anticipating patterns involves probability as relative frequency, combining independent random variables, the normal distribution, sampling distributions. Statistical inference includes estimating population parameters and testing hypotheses.
