accurate - a measure of how close a result is to the true value. An accurate result is very close, bar chart - a way of presenting data when one variable is discrete or categoric and the other is continuous. Numerical values of variables are represented by the height or length of lines or rectangles of equal width, categoric variable - a variable that can take on one of a limited, and usually fixed, number of possible values, continuous variable - a variable that has values that can be any number between a maximum and a minimum, control variable - a variable that you have to keep the same in an investigation, dependent variable - a variable that changes when you change the independent variable, discrete variable - a variable that can only have whole number values, economic impacts - the effects of an application of science that are to do with money, environmental - relating to the natural world and the impact of human activity on it condition, ethical issues - relating to moral principles or the branch of knowledge dealing with these, fair test - an investigation in which all the variables are kept constant except the variable that the investigator changes and the variable that is measured, hazard - a possible source of danger, hypothesis - an idea that is a way of explaining scientists’ observations, independent variable - a variable you change that changes the dependent variable, line graph - a way of representing results when there are two numerical variables, line of best fit - a smooth line on a graph that travels through or very close to as many of the points plotted as possible, model - a description, analogy, or equation that helps you to explain the physical world, normal distribution - a function that represents the distribution of many random variables as a symmetrical bell-shaped graph, outlier - a result that is very different from the other measurements in a data set, peer review - peer review is the checking and evaluation of a scientific paper by other expert scientists in order to help decide whether or not the paper should be published, precise - this describes a set of repeat measurements that are close together, prediction - a statement that says what you think will happen, random error - an error that caused there to be a random difference between measurement and true value each time you measure it, relationship - the way in which two or more people or things are connected, repeatable - a measure of how close values are to each other when an experiment is repeated with the same equipment, reproducible - when other people carry out an investigation and get similar results to the original investigation the results are reproducible, resolution - a measure of the smallest object which can be seen using an instrument, risk - the chance of damage or injury from a hazard, variable - a quantity that can change, for example, time, temperature, length, mass, uncertainty - the doubt in the result because of the way that the measurement is made,
