📚 Cross-curricular Integrated Question Practice for Year 7 CCEA Statistics | Year 7 CCEA 统计：跨学科综合题型训练

Statistics is not just a standalone maths topic; it is a powerful tool embedded in every subject you study. In Year 7 CCEA, you are expected to collect, represent and interpret data across geography, science, history, PE, art and more. This article provides integrated question training that helps you apply the same statistical skills – reading tables and charts, calculating the mean, mode, median and range, and interpreting pictograms and pie charts – to real problems in other disciplines. Each section gives you a typical cross-curricular scenario, a set of practice questions, and a step-by-step solution.

统计并不仅仅是一个独立的数学主题，它是一门融入你所学的每一门学科中的强大工具。在 CCEA 七年级课程中，你需要跨地理、科学、历史、体育、艺术等学科来收集、展示和解读数据。本文提供跨学科综合题型训练，帮助你运用相同的统计技能——阅读表格与图表，计算平均数、众数、中位数和极差，解读象形图和饼图——解决其他学科中的真实问题。每个小节都会给出一个典型的跨学科情境、一组练习题以及逐步求解的过程。

1. Geography: Interpreting Bar Charts and Tables | 地理：解读柱状图与表格

Geography frequently uses statistical displays such as bar charts and tables to present data like city populations, annual rainfall, or temperature trends. In Year 7 CCEA, you are expected to read values directly from the display, compare categories, and calculate the range – the difference between the highest and lowest values. Always check the axis labels and the title so you know exactly what the numbers represent.

地理学科经常使用柱状图和表格等统计图表来展示城市人口、年降雨量或气温变化趋势等数据。在 CCEA 七年级课程中，要求你能够直接从图表中读取数值、比较类别并计算极差——即最大值与最小值之差。务必检查坐标轴标签和标题，以便确切知道这些数字代表什么。

Consider the rainfall data for five cities in Northern Ireland in 2023.

来看一下2023年北爱尔兰五个城市的降雨量数据。

Questions: (a) Which city recorded the highest rainfall? (b) What is the range of rainfall across these five cities?

问题：(a) 哪个城市的降雨量最大？(b) 这五个城市降雨量的极差是多少？

Solution: (a) By scanning the ‘Rainfall’ column we see 920 mm is the largest value, so Londonderry had the highest rainfall. (b) Range = maximum – minimum = 920 mm – 760 mm = 160 mm. The rainfall varies by 160 mm across the five cities. This range tells you about the spread of the data.

解答：(a) 浏览“Rainfall”一列，我们看到920 mm为最大值，因此伦敦德里降雨量最大。(b) 极差 = 最大值 – 最小值 = 920 mm – 760 mm = 160 mm。这五个城市的降雨量相差160 mm。极差告诉你数据的分散程度。

2. Science: Recording Experimental Data | 科学：记录实验数据

In science investigations you routinely collect measurements, record them in tables, and use the data to draw conclusions. Common Year 7 skills include reading values, calculating total change, and finding the average rate of growth. For example, a plant-growth experiment can produce a simple table that you must interpret statistically.

在科学探究中，你通常需要收集测量数据、将其记录在表格中，并用数据得出结论。七年级常见的技能包括读取数值、计算总变化量以及求平均增长速率。例如，一项植物生长实验可以产生一张简单的表格，你必须从统计角度进行解读。
