AP Statistics Course Outline

Following is an outline of the major topics covered by the AP Statistics Exam. The ordering here is intended to define the scope of the course but not necessarily the sequence. The percentages in parentheses for each content area indicate the coverage for that content area in the exam.

I. Exploring Data: Describing patterns and departures from patterns (20%–30%) Exploratory analysis of data makes use of graphical and numerical techniques tostudy patterns and departures from patterns. Emphasis should be placed oninterpreting information from graphical and numerical displays and summaries.

A.Constructing and interpreting graphical displays of distributions of univariate data (dotplot, stemplot, histogram, cumulative frequency plot)

The AP Statistics Exam is made up of two parts: a multiple-choice section and a free response section. The entire test lasts three hours. Here's how the time is allotted.

It clearly lays out the course content and describes the exam and the AP Program in general.

1. Center and spread

2. Clusters and gaps

3. Outliers and other unusual features

4. Shape

B. Summarizing distributions of univariate data

1. Measuring center: median, mean

2. Measuring spread: range, interquartile range, standard deviation

3. Measuring position: quartiles, percentiles, standardized scores(z-scores)

4. Using boxplots

5. The effect of changing units on summary measures

C. Comparing distributions of univariate data (dotplots,back-to-back stemplots, parallel boxplots)

1. Comparing center and spread: within group,between group variation

2. Comparing clusters and gaps

3. Comparing outliers and other unusual features

See the Robert DE BEAUCHAMP Lord of Hache Entry for this Couple's Children and Descendants. Lucy DE MOHUN (Reynold DE Lord of Dunster 2, Reynold DE Lord of Dunster ((Sir)) 1) was born about 1240 in Dunster, Williton, Somerset, England. Lucy married (Sir) John DE GREY (See Link for Ancestry), son of Richard DE GREY Lord Of Codnor and Lucy DE. Descendants of mahunclan. Gilbert married Agnes MacDonald circa 1380. Daughter of John MacDonald and Grand daughter of Angus Og, Lord of the Isles who was the founder of the MacDonald Family known as the 'Macdonalds of Glencoe', the descendants of whom were the victims of the 'Massacre of Glencoe'. Research by G Lewis-Dean indicates Agnes was a descendant of King.
