AP istatistik kurslarımız tecrübeli AP eğitmenlerimizle birlikte işlenmektedir. Bu hocalarımızın artısı yeni AP stamüfredatına tam uyumlu olmalarıdır. Sınavda karşınıza çıkacak her zorluğa hazırlayan Test Prep AP istatistik özel ders, hafta içi ve hafta sonu programlarında verilir.

AP İstatistik Ders Müfredatı

AP İstatistikleri dersi, öğrencilere veri toplama, analiz etme ve sonuç çıkarma ile ilgili temel kavram ve araçları tanıtmaktadır. AP İstatistik dersinde dört tema vardır:

  1. Verileri, örnekleme
  2. Deneyleri keşfetme
  3. Kalıpları tahmin etme
  4. İstatistiksel çıkarım.

Öğrenciler, kavramsal anlayış geliştirdikçe teknoloji, araştırmaları kullanırlar. Kolejlerde ve üniversitelerde, istatistik dersi alan öğrencilerin sayısı, matematik dersi alan öğrencilerin sayısı kadar fazladır. Bu giriş seviyesindeki istatistikleri dersi, genellikle sosyal bilimler, sağlık bilimleri ve işletme gibi bölümler için gereklidir. Her dönem yaklaşık 236.000 üniversite öğrencisi bir matematik veya istatistik bölümü tarafından sunulan istatistik dersine kayıt oluyor. Bilim, mühendislik ve matematik bölümleri genellikle istatistik dersi olarak üst düzey bir matematik tabanlı ders alırlar. AP İstatistik kursu üniversiteye hazırlıkta ve girişte  etkili derstir.

III . Anticipating Patterns: Exploring random phenomena using probability and simulation (20%–30%)

Probability is the tool used for anticipating what the distribution of data should look like under a given model.

A . Probability
