GCSE科学考试如何备考？哪能少了背这些单词，GCSE阶段的科学类课程主要包括GCSE生物、GCSE化学、GCSE物理、GCSE Combined Science等。对于中国学生而言，GCSE科学类课程难点不只在于知识的掌握，更在于适应全英文授课、掌握科学专业词汇以及全英文答题等方面。可以说，中国学生掌握了科学课程专有英文词汇，语言方面过关，GCSE阶段科学类课程的学习可以少一半烦恼！
英国最大的考试局——AQA考试局综合其科学课程的内容，给大家总结了一份科学类课程专用词汇表，其中汇集了GCSE科学课程学习者需要掌握的最基本的专用英语词汇。
Data
Information, either qualitative or quantitative, that has been collected.
收集到的定性或定量信息。
Error
See also uncertainty.
同“uncertainty”。
Measurement error
The difference between a measured value and the true value.
测量值与真实值之间的误差。
Anomalies
These are values in a set of results which are judged not to be part of the variation caused by random uncertainty.
一组结果中的值，这些结果被判断为不属于由不确定性变化引起的部分结果。
Random error
These cause readings to be spread about the true value, due to results varying in an unpredictable way from one measurement to the next. Random errors are present when any measurement is made, and cannot be corrected. The effect of random errors can be reduced by making more measurements and calculating a new mean.
由于结果在不同的测量中以不可预测的方式变化，这将导致读数围绕真实值分布。进行任何测量时都会出现随机误差，并且随机误差不能被纠正。随机误差的影响可以通过进行多次测量和计算新的平均值来减少。
Systematic error
These cause readings to differ from the true value by a consistent amount each time a measurement is made. Sources of systematic error can include the environment, methods of observation or instruments used. Systematic errors cannot be dealt with by simple repeats. If a systematic error is suspected, the data collection should be repeated using a different technique or a different set of equipment, and the results compared.
每次测量时，读数与真实值的差值是一致的。系统误差的来源包括环境、测量方法或使用的仪器。系统误差不能通过简单的重复实验解决。如果怀疑存在系统性误差，则应使用不同技术或不同设备重复数据收集，并比较结果。
Zero error
Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, eg the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty.
当被测量的真值为零时，测量系统给出了错误读数的指示，如无电流通过时，安培计上的指针指向不是零。零误差可能导致系统不确定性。
Evidence
Data which has been shown to be valid.
已被证明为有效的数据。
Fair test
A fair test is one in which only the independent variable has been allowed to affect the dependent variable.
公平测试只允许自变量影响因变量。
Hypothesis
A proposal intended to explain certain facts or observations.
为解释某些事实或观察而提出的提议。
Interval
The quantity between readings, eg a set of 11 readings equally spaced over a distance of 1 metre would give an interval of 10 centimetres.
读数之间的间隔量(如一组11个读数，在1米的距离上等距分布，则间距为10厘米)。
Precision
Precise measurements are ones in which there is very little spread about the mean value. Precision depends only on the extent of random errors – it gives no indication of how close results are to the true value.
精确测量是指在平均值上有很小的误差。精度只取决于随机误差的范围，但并没有指出结果与真实值有多接近。
