AP Statistics Scores - Learn What You Need for College Statistics is a popular Advanced Placement course with over 200,000 students taking the exam annually. Students who have other options and interests, however, should be aware that AP Statistics is accepted for course credit and placement by fewer colleges than many other AP subjects.   About the AP Statistics Course and Exam The Advanced Placement Statistics course is a non-calculus-based course that is the equivalent of many one-semester, introductory college statistics classes. The exam covers  exploring data, sampling and experimentation, anticipating patterns, and statistical inference. Each of these topics encompasses several subtopics: Exploring Data. Students learn to analyze different types of graphs and data displays. Key topics include spread, outliers, median, mean, standard deviation, quartiles, percentages, and more. Students also learn to compare different data sets to find patterns and draw conclusions. This section encompasses 20 to 30 percent of the exam questions.Sampling and Experimentation. Students learn about proper and effective methods of data collection and data analysis. Students learn about the characteristics of well-conducted surveys, and they learn about the issues attached to different types of populations and selection methods. Important topics include random sampling, control groups, placebo effect, and replication. This section accounts for 10 to 15 percent of the exam.Anticipating Patterns. This section focuses on probabilities and simulation, and students learn what data should look like for a given model. Topics covered include the addition rule, multiplication rule, conditional proba bility, normal distribution, random variables, t-distribution, and chi-square distribution. 20 to 30 percent of the AP exam covers these topics. Statistical Inference. In this section, students learn how to select appropriate models for a given task. Students study how to estimate population parameters and test hypotheses. Important topics include margins of error, confidence levels, p-values, types of errors, and more. This is the largest area of course content and accounts for 30 to 40 percent of the exam. AP Statistics Score Information In 2018,  222,501 students took the exam. The mean score was a 2.88, and roughly 60.7 percent  of students (135,008 of them) scored a 3 or higher.

Especially vs. Specially

Especially vs. Specially Especially vs. Specially Especially vs. Specially By Ali Hale One of our readers recently asked if we could explain the difference between especially and specially. The words especial and special can be used almost interchangeably. They both mean something which was â€Å"out of the ordinary† or even â€Å"exceptional†. Merriam-Webster defines especial as meaning â€Å"being distinctive†: as a: directed toward a particular individual, group, or end [especial greetings to his son] [especial care to speak clearly] b: of special note or importance : unusually great or significant [especial relevance] c: highly distinctive or personal : peculiar [especial dislike for music] d: close, intimate [especial crony] e: specific, particular [especial destination in mind] The two words are synonyms, and often either is appropriate: My grandmother’s ninetieth birthday was an occasion of especial joy. My grandmother’s ninetieth birthday was an occasion of special joy. Both of these are correct, however, especial implies that something less good exists, whereas something special doesnt need to be compared against anything. Merrian-Webster explains the difference like this: â€Å"special stresses having a quality, character, identity, or use of its own . especial may add implications of preeminence or preference [especial importance] .† Note that special can be used as a noun, whereas especial cannot, in cases such as â€Å"It’s always worth checking the specials in the supermarket.† Especially or specially? When it comes to the adjectival forms, especially should always be used. It modifies a verb, adverb or adjective and means â€Å"particularly† or â€Å"exceptionally†: His train was running especially late that day. We were especially happy to see you. I put the cake especially high. Specially is becoming more common but still tends to sound rather informal, even a little child-like (â€Å"I drew this picture specially for you!†) There is a lot of debate around whether â€Å"specially† is appropriate in some cases, but if you want to be sure, stick with â€Å"especially†.
