Appendix8.7 Presentation of dataThe solidus (/) is to be used for separating the quantity and the unit in tables, graphs and charts, e.g. time / sfor time in seconds.(a) Tables• Each column of a table should be headed with the physical quantity and the appropriate unit,e.g. time / s.• The column headings of the table can then be directly transferred to the axes of a constructed graph.(b) Graphs• Unless instructed otherwise, the independent variable should be plotted on the x-axis (horizontalaxis) and the dependent variable plotted on the y-axis (vertical axis).• Each axis should be labelled with the physical quantity and the appropriate unit, e.g. time / s.• The scales for the axes should allow the majority of the graph grid to be used in both directions, andbe based on sensible ratios, e.g. 2 cm on the graph grid representing 1, 2 or 5 units of the variable(or 10, 20 or 50 units, etc.).• The graph is the whole diagrammatic presentation, including the best-fit line when appropriate. Itmay have one or several data sets plotted on it.• Points on the curve should be clearly marked as crosses (x) or encircled dots (☼).• Large ‘dots’ are penalised. Each data point should be plotted to an accuracy of better than one halfof each of the smallest squares on the grid.• A best-fit line (trend line) should be a single, thin, smooth straight-line or curve. The line does notneed to coincide exactly with any of the points; where there is scatter evident in the data, Examinerswould expect a roughly even distribution of points either side of the line over its entire length. Pointsthat are clearly anomalous may be ignored when drawing the best-fit line.• The gradient of a straight line should be taken using a triangle whose hypotenuse extends over atleast half of the length of the best-fit line, and this triangle should be marked on the graph.(c) Numerical results• Data should be recorded so as to reflect the precision of the measuring instrument.• The number of significant figures given for calculated quantities should be appropriate to the leastnumber of significant figures in the raw data used.8.8 FormsThis section contains copies of the following forms, together with instructions on how to complete them:• Experiment Form• Individual Candidate Record Card• Coursework Assessment Summary Form46 Cambridge IGCSE Physics 0625.
