📚 Year 7 WJEC Statistics: Oral & Aural Exam Preparation | 口语/听力备考专项
Statistics is not just about numbers and graphs – in many Year 7 WJEC classrooms, you are asked to talk about data, listen to instructions for collecting information, and discuss your findings with others. This article focuses on the speaking and listening skills you need to feel confident when discussing statistics in English. Whether you are preparing for an oral presentation, a group discussion, or a listening test that involves data, these strategies and key phrases will help you communicate clearly and accurately.
统计学不仅仅是数字和图表——在许多七年级 WJEC 课堂上，你需要口头讨论数据、听取收集信息的指令，并与他人交流你的发现。本文专注于你在用英语讨论统计学时所需要掌握的口语和听力技能。无论你是在准备口头展示、小组讨论，还是涉及数据的听力测试，这些策略和关键短语都将帮助你清晰、准确地进行交流。
1. Key Statistical Vocabulary for Speaking | 统计学口语关键词汇
Before you can speak about statistics, you must be comfortable with core terms. Practise saying words like ‘data’, ‘survey’, ‘frequency’, ‘tally’, ‘mean’, ‘median’, ‘mode’ and ‘range’ aloud. Use a mirror or record yourself to check pronunciation. For example, ‘data’ can be pronounced ‘day-tuh’ or ‘dah-tuh’; both are acceptable, but consistency matters. Repeat these words in short sentences: ‘I collected data using a tally chart.’ ‘The mode is the most common value.’
在讨论统计之前，你必须熟悉核心术语。大声练习说出像 data、survey、frequency、tally、mean、median、mode 和 range 这样的词。用镜子观察自己或录音检查发音。例如，’data’ 可以读作 ‘day-tuh’ 或 ‘dah-tuh’，两种都可以，但重要的是保持一致。在短句中重复这些词：’I collected data using a tally chart.’ ‘The mode is the most common value.’
| English Term | 中文术语 | Sample Spoken Sentence |
|---|---|---|
| frequency | 频数 | The frequency of 5 is the highest. |
| mean | 平均数 | To find the mean, add all numbers and divide. |
| range | 极差 | The range tells us how spread out the data is. |
2. Describing Bar Charts and Pictograms Orally | 口头描述条形图和象形图
When you present a bar chart, use clear phrases like ‘The bar chart shows the number of students who prefer each fruit.’ or ‘The highest bar represents apples, which had a frequency of 12.’ Describe the axes: ‘The horizontal axis shows the categories, and the vertical axis shows the frequency.’ For pictograms, say ‘Each circle represents 2 people, so half a circle stands for 1 person.’ Practise linking sentences with ‘while’ and ‘whereas’: ‘Oranges were chosen by 8 students, whereas bananas were chosen by only 3.’
当你展示条形图时，使用清晰的短语，如 ‘The bar chart shows the number of students who prefer each fruit.’ 或 ‘The highest bar represents apples, which had a frequency of 12.’ 描述坐标轴：’The horizontal axis shows the categories, and the vertical axis shows the frequency.’ 对于象形图，可以说 ‘Each circle represents 2 people, so half a circle stands for 1 person.’ 练习用 ‘while’ 和 ‘whereas’ 连接句子：’Oranges were chosen by 8 students, whereas bananas were chosen by only 3.’
Listen to a partner describe a graph and try to draw it from their words alone. This listening exercise forces you to pay attention to details like scale, labels and values. Afterwards, compare your drawing with the original and discuss any misunderstandings.
听一个同伴描述一幅图表，然后仅凭他们的话试着把它画出来。这个听力练习迫使你注意比例、标签和数值等细节。之后，将你的图画与原图比较，并讨论任何误解。
3. Talking about Averages: Mean, Median, Mode and Range | 讨论平均数：平均数、中位数、众数和极差
Use precise language when explaining how to calculate each measure. Say ‘To find the mean, I add up all the values and then divide by how many there are.’ For median, say ‘I put the numbers in order and then find the middle one. If there are two middle numbers, I find their mean.’ For mode, say ‘The mode is the number that appears most often.’ For range, say ‘I subtract the smallest value from the largest value.’ Practise these explanations until they feel natural.
在解释如何计算各项指标时，要使用精确的语言。说 ‘To find the mean, I add up all the values and then divide by how many there are.’ 对于中位数，说 ‘I put the numbers in order and then find the middle one. If there are two middle numbers, I find their mean.’ 对于众数，说 ‘The mode is the number that appears most often.’ 对于极差，说 ‘I subtract the smallest value from the largest value.’ 练习这些解释，直到它们感觉自然。
In a speaking test, you might be given a small data set and asked to describe it. For example, with the numbers 3, 5, 5, 7, 9, you could say ‘The mean is 5.8, the median is 5, the mode is 5 and the range is 6.’ Then add a comparison: ‘Because the mean and median are close, the data is fairly symmetrical.’
在口试中，你可能会得到一个小的数据集并被要求描述它。例如，对于数字 3, 5, 5, 7, 9，你可以说 ‘The mean is 5.8, the median is 5, the mode is 5 and the range is 6.’ 然后添加一个比较：’Because the mean and median are close, the data is fairly symmetrical.’
4. Interpreting Pie Charts in Speech | 用口语解读饼图
When talking about a pie chart, use fractions and percentages. Say ‘The blue sector represents three eighths of the whole, which is 37.5%.’ Mention the largest and smallest sectors: ‘The yellow sector is the largest, taking up nearly half the pie.’ Avoid saying ‘the pie chart tells us about people’ – be specific: ‘The pie chart shows how Year 7 students travel to school.’ Practise phrases like ‘a quarter of’, ‘a third of’, ‘just over half’, and ‘slightly less than a fifth’.
谈论饼图时，使用分数和百分比。说 ‘The blue sector represents three eighths of the whole, which is 37.5%.’ 提及最大和最小的扇形：’The yellow sector is the largest, taking up nearly half the pie.’ 避免说 ‘the pie chart tells us about people’——要具体：’The pie chart shows how Year 7 students travel to school.’ 练习像 ‘a quarter of’、’a third of’、’just over half’ 和 ‘slightly less than a fifth’ 这样的短语。
Listen to a teacher or a recording describing a pie chart and try to answer comprehension questions without seeing the chart. For example, ‘Which sector represents the most popular choice?’ or ‘What fraction of students walk to school?’ This builds your ability to absorb statistical information through listening alone.
听老师或录音描述一幅饼图，并尝试在看不到图表的情况下回答理解性问题。例如 ‘Which sector represents the most popular choice?’ 或 ‘What fraction of students walk to school?’ 这能锻炼你仅通过听力吸收统计信息的能力。
5. Expressing Probability in Everyday Statistical Talk | 在日常统计谈话中表达概率
Probability appears in Year 7 statistics through words like ‘likely’, ‘unlikely’, ‘certain’, ‘even chance’, and ‘impossible’. Speak using these terms accurately. For example, ‘It is likely that it will rain tomorrow because the forecast shows an 80% chance.’ Or ‘When I roll a fair dice, there is an even chance of getting an odd number.’ Use ‘certain’ only when the probability is 1: ‘It is certain the sun will rise tomorrow.’
概率通过 ‘likely’、’unlikely’、’certain’、’even chance’ 和 ‘impossible’ 等词汇出现在七年级统计中。准确地使用这些术语说话。例如 ‘It is likely that it will rain tomorrow because the forecast shows an 80% chance.’ 或者 ‘When I roll a fair dice, there is an even chance of getting an odd number.’ 只有当概率为 1 时才使用 ‘certain’：’It is certain the sun will rise tomorrow.’
Practise converting between fractions, decimals and percentages in speech: ‘The probability of picking a red card from a standard pack is one half, which is also 0.5 or 50%.’ This fluency will help you in both oral exams and group discussions.
练习在口语中进行分数、小数和百分数之间的转换：’The probability of picking a red card from a standard pack is one half, which is also 0.5 or 50%.’ 这种流利度将有助于你在口试和小组讨论中的表现。
6. Asking and Answering Questions about Data | 对数据提问和回答
Typical listening tasks require you to answer questions based on spoken data descriptions. Prepare by learning standard question words: ‘How many?’, ‘What is the difference between…?’, ‘Which category had the highest/lowest frequency?’, ‘What was the total number of…?’ and ‘How does … compare to …?’ Practise using complete sentences in your answers, e.g. ‘The difference between the two groups is 7.’ instead of just ‘7’.
典型的听力任务要求你根据口述的数据描述回答问题。通过学习标准疑问词来准备：’How many?’、’What is the difference between…?’、’Which category had the highest/lowest frequency?’、’What was the total number of…?’ 以及 ‘How does … compare to …?’ 练习用完整句子作答，例如 ‘The difference between the two groups is 7.’ 而不是只说 ‘7’。
For speaking, you should be able to ask follow-up questions. For instance, if a partner says ‘The mean time spent on homework is 45 minutes’, you could ask ‘Did you include students who did no homework?’ or ‘What was the sample size?’ This shows higher-level statistical thinking.
对于口语，你应该能提出后续问题。例如，如果同伴说 ‘The mean time spent on homework is 45 minutes’，你可以问 ‘Did you include students who did no homework?’ 或者 ‘What was the sample size?’ 这表明了更高层次的统计思维。
7. Listening to Data Collection Instructions | 听取数据收集指令
In a lesson, your teacher might give verbal instructions for a survey, such as ‘Ask 20 people what their favourite colour is and record the results in a frequency table. Then draw a bar chart with the categories on the horizontal axis and frequencies up to 20 on the vertical axis.’ Listen for key numbers and steps. Jot down notes while listening: numbers, categories, and action words like ‘record’, ‘tally’, ‘draw’, ‘label’.
在课堂上，你的老师可能会口头给出调查指令，例如 ‘Ask 20 people what their favourite colour is and record the results in a frequency table. Then draw a bar chart with the categories on the horizontal axis and frequencies up to 20 on the vertical axis.’ 注意听关键数字和步骤。边听边快速记下：数字、类别以及如 ‘record’、’tally’、’draw’、’label’ 这样的动作词。
To practise, find a short audio or have a friend read instructions while you sketch the requested diagram. Compare your result with the expected output. Common mistakes include using the wrong scale or missing a label – listening carefully prevents these errors.
为了练习，找一段简短的音频或让一个朋友读出指令，同时你画出要求的图表。将你的结果与预期输出进行比较。常见的错误包括使用了错误的比例或遗漏了标签——仔细听可以避免这些错误。
8. Group Discussion on Survey Results | 关于调查结果的小组讨论
When discussing survey findings in a group, use phrases like ‘In our survey, we found that…’, ‘According to the data, …’, and ‘One interesting result was …’. Support your opinions with numbers: ‘60% of students said they prefer chips, which suggests it is the most popular lunch choice.’ Agree and disagree politely: ‘I agree with your point, but I think we should also consider…’ or ‘I see it slightly differently because…’.
在小组中讨论调查结果时，使用诸如 ‘In our survey, we found that…’、’According to the data, …’ 和 ‘One interesting result was …’ 这样的短语。用数字支持你的观点：’60% of students said they prefer chips, which suggests it is the most popular lunch choice.’ 有礼貌地表示同意和不同意：’I agree with your point, but I think we should also consider…’ 或 ‘I see it slightly differently because…’。
In an oral exam simulation, you may be asked to take part in a role play where you present findings and respond to questions. Focus on turn-taking and clarity. Use ‘Could you repeat that?’ or ‘Sorry, I didn’t catch the exact figure.’ when you need clarification. This not only aids communication but also shows good listening skills.
在模拟口试中，你可能会被要求参加角色扮演，展示发现并回答问题。注意轮流发言和清晰表达。当你需要澄清时，使用 ‘Could you repeat that?’ 或 ‘Sorry, I didn’t catch the exact figure.’ 这不仅有助于交流，也体现了良好的听力技能。
9. Common Pronunciation and Intonation Pitfalls | 常见发音和语调陷阱
Many Year 7 learners stumble over ‘th’ sounds in ‘thirty’, ‘third’ and ‘thousand’. Practise slowly: ‘th-ir-ty’ with the tongue between the teeth. The word ‘statistics’ itself has a tricky st-st cluster; break it down: ‘sta-tis-tics’. Numbers like ‘eight’ and ‘eighth’ are often confused – ‘eighth’ has a long ‘tth’ sound at the end. Also, intonation matters: when saying a series of numbers, your voice should go up on each item except the last, which goes down to show completion.
许多七年级学生在 ‘thirty’、’third’ 和 ‘thousand’ 中的 ‘th’ 发音上磕巴。慢慢练习：’th-ir-ty’，舌头放在牙齿之间。’statistics’ 这个词本身有一个棘手的 st-st 辅音群；分解它：’sta-tis-tics’。像 ‘eight’ 和 ‘eighth’ 这样的数字经常被混淆——’eighth’ 结尾有一个长的 ‘tth’ 音。此外，语调很重要：当说出一系列数字时，你的声音应该在每个项目上升，除了最后一个下降以表示结束。
Record yourself reading a short statistical paragraph and listen back. Check for clear ‘s’ versus ‘z’ sounds (e.g. ‘graphs’ ends with an ‘f’ sound, but ‘numbers’ has a ‘z’ sound). These small differences greatly affect your speaking score in an oral assessment.
录下自己朗读一段简短的统计段落并回听。检查清晰的 ‘s’ 对 ‘z’ 音（例如 ‘graphs’ 以 ‘f’ 音结尾，但 ‘numbers’ 有一个 ‘z’ 音）。这些细微的差别会在口试中很大程度上影响你的口语评分。
10. Oral Exam Practice Scenarios | 口试练习情景
Set up a mock oral test: a partner gives you a data set (e.g. shoe sizes of 15 classmates) and asks you to describe the distribution, find the mode and median, and suggest what the data shows. Time your response: aim for 1-2 minutes of fluent speech. Use a checklist: did you name the data set? Did you state the mode and median correctly? Did you mention the range and any unusual values? Did you conclude with a real-world observation?
设置一个模拟口试：一个同伴给你一个数据集（例如 15 个同学的鞋码），并要求你描述分布、找出众数和中位数，并建议数据反映了什么。计录你的回答时间：力争进行 1-2 分钟的流利说话。使用一个检查表：你是否命名了数据集？你是否正确陈述了众数和中位数？你是否提到了极差和任何异常值？你是否以一个现实观察收尾？
Another useful exercise is to listen to a short news report containing statistics and summarise it verbally. For instance, ‘In a survey of 200 teens, 75% use social media daily. The remaining 25% use it less often. The most common platform was Snapchat, chosen by 40% of respondents.’ This trains both listening comprehension and the ability to rephrase data in your own words, a key skill for WJEC oral assessments.
另一个有用的练习是听一段包含统计数据的简短新闻报道，并口头总结。例如，’In a survey of 200 teens, 75% use social media daily. The remaining 25% use it less often. The most common platform was Snapchat, chosen by 40% of respondents.’ 这既训练了听力理解，也训练了用你自己的话重新表述数据的能力，这是 WJEC 口试的关键技能。
