**课程名称：** 统计学入门（面向非数学专业人士） **课程概述：** 本课程旨在帮助非数学专业的学习者轻松掌握现代统计学的基本概念和实用方法。课程将深入浅出地介绍统计学的核心要素，包括： * **统计学基本概念：** 量化、变量与常数、样本与总体、随机性与代表性、参数与统计量、分析单位、数据库构建等。 * **测量尺度与变量类型：** 深入理解名义、顺序、区间和比率等测量尺度，以及连续与离散、参数与非参数等变量类型，并学习它们之间的相互转换。 * **数据描述性统计：** 掌握均值、中位数、众数、极差、方差、标准差等基本统计量，用于有效地描述和总结数据。 * **分布与标准化：** 学习理论分布与实际分布的区别，理解标准化（Z分数）的概念，并掌握正态分布及其重要特性。 * **假设检验：** 掌握假设检验的基本原理、零假设的概率、Z检验、t检验及t分布，并通过置信区间来理解结果的可靠性。 * **常见统计推断方法：** 学习独立样本t检验、重复测量t检验、独立样本和重复测量的方差分析（ANOVA）。 * **关联性与回归分析：** 掌握皮尔逊相关系数以衡量线性关系，并学习简单线性回归和多元线性回归以进行预测和解释。 **教学特色：** 本课程的重点在于**基本原理**而非复杂的数学推导，确保即使是统计学新手也能轻松理解每一个统计程序。授课节奏经过精心设计，以促进对新概念的消化吸收。 **学习支持：** 每节课后都配有**练习题**，帮助巩固所学知识。此外，每部分还将提供**关键统计指标的临界值表格**和**所有练习题的详细解答**，方便学习者检验和纠正学习过程中的偏差。 **目标：** 通过本课程的学习，您将为成为一名统计学专家打下坚实的基础！
In this course you will learn about: basic concepts of statistics (quantification, variables & constants, samples, and populations, randomness, and representativeness, parameters and statistics, units of analysis, databases), scales of measurement (the nominal, the ordinal, the interval, and the ratio scale) and types of variables (continuous & discrete, parametric & nonparametric), how to convert one type of scale into another, basic description of the data (mean, median, mode, range, variance, standard deviation), theoretical & real distributions, standardization (the Z scores), the normal distribution and its properties, hypothesis testing, the probability of the null hypothesis, the Z test, the t-test and the t distributions, the confidence intervals, the independent samples t-test, the repeated measures t-test, the Analysis of Variance (ANOVA) for independent samples and repeated measures, the Pearson correlation, the simple and the multiple linear regression.In all presentations, the focus is moved from mathematical aspects to basic principles behind each statistical procedure, so that each topic is very easy to understand. The rhythm of the presentation is well calibrated to facilitate the understanding of each new concept.Each section is followed by several exercises in which you can consolidate your newly acquired knowledge. In addition, you will receive for each section the tables with critical values for your statistical indicators and a document with all exercises resolved to check if you work correctly.Good luck on your way to becoming an expert in Statistics!
