Comparing UK University Entry Requirements | 英国大学申请要求对照

📚 Comparing UK University Entry Requirements | 英国大学申请要求对照

In Year 8 WJEC Statistics, we learn how to collect, present and interpret data. One fascinating real-life application is comparing university entry requirements across the UK. Different universities set different A-level grade combinations and subject requirements for the same course. By using statistical tools like frequency tables, bar charts and averages, we can uncover patterns and help students make informed choices about their future applications.

在八年级 WJEC 统计学中，我们学习如何收集、展示和解读数据。其中一个引人入胜的现实应用是比较英国各大学的入学要求。不同的大学对同一专业设定的A-level成绩组合和科目要求各不相同。通过使用频率表、条形图和平均数等统计工具，我们可以发现规律，帮助学生就未来的申请做出明智的决策。

1. What Are University Entry Requirements? | 什么是大学入学要求？

In the UK, university entry requirements typically include specific A-level grades, such as A*A*A or AAA, and essential subjects like Mathematics or Chemistry. To make comparisons easier, these grade offers can be converted into UCAS tariff points. An A* grade is worth 56 points, an A is 48, a B is 40, a C is 32, and so on. This numerical system allows us to treat entry requirements as data that can be analysed statistically.

在英国，大学入学要求通常包括特定的A-level成绩，例如A*A*A或AAA，以及数学或化学等必修科目。为了便于比较，这些成绩要求可以转换为UCAS tariff points。一个A*等级值56分，A值48分，B值40分，C值32分，依此类推。这种数字系统使我们能够将入学要求视为可进行统计分析的数据。

2. Collecting Data on Entry Requirements | 收集入学要求数据

We can design a data collection sheet to record the entry requirements for a specific course, such as Chemical Engineering, at a selection of UK universities. Let us imagine we have gathered information for eight universities for the 2025 entry. The table below shows the typical A-level offers, calculated UCAS tariff points and the required subjects.

我们可以设计一个数据收集表，记录选定的英国大学中某一专业（如化学工程）的入学要求。假设我们收集了八所大学2025年入学的信息。下表展示了典型的A-level录取要求、计算出的UCAS分数以及必修科目。

This structured dataset allows us to apply a range of statistical techniques to compare the universities.

这个结构化的数据集使我们能够应用一系列统计技术来比较各大学。

3. Types of Data: Categorical and Numerical | 数据类型：分类与数值

The information we collected contains both categorical and numerical data. University names and required subject names are categorical (qualitative) because they describe categories. UCAS tariff points are discrete numerical data because they are numbers that can be counted and used in calculations. A-level grades such as A*A*A can be treated as ordered categorical data, but once converted to points they become numerical, which is more useful for finding averages and spread.

我们收集的信息既包含分类数据也包含数值数据。大学名称和必修科目名称是分类（定性）数据，因为它们描述类别。UCAS tariff points是离散数值数据，因为它们是可计数并可用于计算的数字。像A*A*A这样的A-level成绩可以被视为有序分类数据，但一旦转换为分数，它们就成了数值数据，这对于计算平均值和离散程度更有用。

4. Frequency Tables: Tallying Subject Requirements | 频率表：统计科目要求

We can use a frequency table to summarise how many universities require each subject. The tally column helps us count systematically. The table below shows the frequency of required subjects across the eight Chemical Engineering courses.

我们可以使用频率表来总结有多少所大学要求每门科目。计数栏帮助我们系统地进行统计。下表显示了八个化学工程课程中必修科目的频率。

Mathematics is required by all eight universities, Chemistry by seven, and Physics only appears as an alternative at Edinburgh. This tells us that strong mathematical ability is universally expected for this course.

数学被全部八所大学列为必修，化学被七所大学要求，而物理仅在爱丁堡大学作为替代选项出现。这告诉我们，该专业普遍期望申请者具备扎实的数学能力。

5. Bar Charts for UCAS Tariff Points | 用条形图展示UCAS分数

A bar chart is an excellent way to compare the UCAS tariff points needed by each university. Each bar represents one university, and its height corresponds to the total points. From our data, we would draw bars reaching 160 for Oxford and Cambridge, 152 for Imperial and UCL, 144 for Manchester, Edinburgh and Bristol, and 136 for Birmingham. The bar chart would immediately highlight that Oxford and Cambridge have the highest point requirements, while Birmingham is the most accessible in this sample.

条形图是比较每所大学所需UCAS分数的绝佳方式。每个条形代表一所大学，其高度对应总分。根据我们的数据，我们会画出牛津和剑桥高达160的条形，帝国理工和UCL为152，曼彻斯特、爱丁堡和布里斯托为144，伯明翰为136。该条形图会立即突出显示牛津和剑桥的分数要求最高，而伯明翰在这个样本中最为容易达到。

6. Pictograms of Required Subjects | 必修科目的象形图

We can represent the frequency of required subjects using a pictogram. If we let one book symbol 📘 represent 2 universities, then Mathematics would be shown with 4 book symbols (8 ÷ 2). Chemistry would need 3½ symbols (7 ÷ 2 = 3.5), and Physics would be shown with half a symbol (1 ÷ 2 = 0.5). Pictograms make frequency data visually engaging, although partial symbols can be less precise than a bar chart.

我们可以使用象形图来表示必修科目的频率。如果我们让一个书本符号📘代表2所大学，那么数学科将用4个书本符号表示（8 ÷ 2）。化学需要3½个符号（7 ÷ 2 = 3.5），物理则用半个符号表示（1 ÷ 2 = 0.5）。象形图使频率数据视觉上更具吸引力，但部分符号可能不如条形图精确。

7. Pie Charts: Proportions of Qualification Types | 饼图：资格类型比例

We can categorise the offers by their A-level grade combination and construct a pie chart. First, we count how many universities fall into each category:

我们可以按A-level成绩组合对录取要求进行分类，并制作饼图。首先，统计每个类别中有多少所大学：
