📚 KS3 OCR Statistics: Interdisciplinary Mixed Question Practice | KS3 OCR 统计：跨学科综合题型训练

Statistics connects every subject you study, from recording plant heights in science to mapping population changes in geography. This guide gives you a series of interdisciplinary mixed questions, designed to help you sharpen the skills you need for the OCR KS3 curriculum. You will practise collecting data, drawing graphs, calculating averages, interpreting probability in real contexts, and more.

统计学连接着你所学的每一门学科，从记录科学中的植物高度到绘制地理中的人口变化图。本指南为你提供一系列跨学科的综合题型，旨在帮助你磨练 OCR KS3 课程所需的各项技能。你将练习收集数据、绘制图表、计算平均数、在真实情境中解读概率等内容。

1. Collecting and Organising Data in Science Experiments | 收集和整理科学实验中的数据

In any science investigation, the first step is to decide what data to gather and how to record it clearly. A well-structured table with headings and units prevents mistakes later on. For example, when measuring the bounce height of a ball dropped from different heights, you might use a table with columns ‘Drop height (cm)’, ‘Bounce 1 (cm)’, ‘Bounce 2 (cm)’, and ‘Average bounce (cm)’.

在任何科学探究中，第一步就是决定收集哪些数据以及如何清晰地记录。一张标题明确并带有单位的表格可以避免之后的错误。例如，测量从不同高度落下的球的反弹高度时，你可以使用包含“下落高度 (cm)”、“第一次反弹 (cm)”、“第二次反弹 (cm)”、“平均反弹 (cm)”这几栏的表格。

Tally charts are a quick way to record categorical data, such as the colour of flowers in a field. You can group tallies in fives using a diagonal stroke through four vertical lines. This makes counting the total frequency much faster.

计数表是记录类别数据（例如田野中花朵的颜色）的快捷方式。你可以用四竖一横的划线法每五个一组来标记。这样能让总数统计快得多。

Once data is collected, you often need to organise it into a grouped frequency table for large sets of numbers. Choose equal class intervals, like 0–9, 10–19, to reveal patterns without overcomplicating the data.

收集完数据后，对于大的数字集合，你通常需要将其整理成分组频数表。选择相等的组距，如 0–9、10–19，既能揭示模式，又不会让数据过于复杂。

2. Displaying Data: Charts for Geography and Science | 展示数据：地理和科学中的图表

Bar charts are ideal when you want to compare distinct categories. For instance
