Annotate - Answer- Add notation or labelling to a graph, diagram or other drawing. Apply - Answer- Use information in a new context. Calculate - Answer- Work out the value of something. Comment - Answer- Make a judgement based on a value. Compare - Answer- Identify similarities and/or differences. Construct - Answer- Assemble a piece of equipment (during practical work). Deduce - Answer- Draw conclusions from information provided. Describe - Answer- Give an account of. Design - Answer- Set out how something will be done. Determine - Answer- Use given data or information to obtain an answer. Discuss - Answer- Present key points. Distinguish - Answer- List the differences between different items. Draw - Answer- Produce a diagram. Evaluate - Answer- Judge from available evidence. Explain - Answer- Give reasons. Identify - Answer- Provide an answer from a number of alternatives. List - Answer- List a number of features or points without further elaboration. Measure - Answer- Find an item of data for a given quantity Outline - Answer- Set out main characteristics. Predict - Answer- Give a plausible outcome. Show - Answer- Provide structured evidence to reach a conclusion. Sketch - Answer- Draw approximately. Solve - Answer- Arrive at answer using a numerical or algebraic method. State - Answer- Express in clear terms. Suggest - Answer- Present a possible case/solution. Write - Answer- Recall basic knowledge possibly after a simple numerical manipulation. Accuracy - Answer- If a measurement result is judged to be close to the true value. Calibration - Answer- Marking a scale on a measuring instrument. This involves establishing the relationship between indications of a measuring instrument and standard or reference quantity values, which must be applied. For example, placing a thermometer in melting ice to see whether it reads 0 °C, in order to check if this has been done correctly. Data - Answer- Information, either qualitative or quantitative, that has been collected. Measurement error - Answer- The difference between a measured value and the true value. Anomalies - Answer- These are values in a set of results which are judged not to be part of the variation caused by random uncertainty. Random error - Answer- These cause readings to be spread about the true value, due to results varying in an unpredictable way from one measurement to the next. They are present when any measurement is made, and cannot be corrected. Their effect can be reduced by making more measurements and calculating a new mean. Systematic errors - Answer- These cause readings to differ from the true value by a consistent amount each time a measurement is made. Sources can include the environment, methods of observation or instruments used. They cannot be dealt with by simple repeats. If one is suspected, the data collection should be repeated using a different technique or a different set of equipment, and the results compared. Zero error - Answer- 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. May result in a systematic uncertainty. Evidence - Answer- Data which has been shown to be valid. Fair test - Answer- A fair test is one in which only the independent variable has been allowed to affect the dependent variable. Hypothesis - Answer- A proposal intended to explain certain facts or observations. Interval - Answer- The quantity between readings, e.g. for a set of 11 readings equally spaced over a distance of 1 metre it would be 10 centimetres. Precise - Answer- Measurements have very little spread about the mean value. Depends only on the extent of random errors - it gives no indication of how close results are to the true value. Prediction - Answer- A statement suggesting what will happen in the future, based on observation, experience or a hypothesis. Range - Answer- The maximum and minimum values of the independent or dependent variables; important in ensuring that any pattern is detected. For example, can be eithe
