Abstract

Abstract This study investigated first‐year undergraduate statistics students’ statistical problem‐solving skills on the probability of the union of two events, conditional probability, binomial probability distribution, probabilities for x‐limits using the z‐distribution, x‐limit associated with a given probability for a normal distribution, estimating the y‐value using a regression equation, and hypothesis testing for a single population mean when a population standard deviation is unknown. The study was a descriptive case study and employed a mixed‐method research approach. Data were collected through content analysis of a statistics course examination script of 120 first‐year undergraduate students of statistics in an open distance‐learning university in South Africa. Polya's Model of Problem Solving was used as the framework of analysis. The study revealed that the students, in general, had poor statistical problem‐solving skills.

一年级本科生统计问题解决能力

摘要本研究调查了统计专业一年级学生的统计问题解决能力，包括两个事件的并集概率、条件概率、二项概率分布、使用z -分布的x -极限概率、与正态分布的给定概率相关的x -极限概率、使用回归方程估计y -值，以及在总体标准差未知的情况下对单个总体均值的假设检验。本研究为描述性案例研究，采用混合方法研究方法。数据是通过对南非一所开放远程教育大学120名一年级统计学本科生的统计课程考试脚本的内容分析收集的。采用Polya的问题解决模型作为分析框架。研究表明，总体而言，学生解决统计问题的能力较差。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
