II.1 the concept of variables II.1.1 introduction the ultimate scientific aim is to understand causal links between events: WHY ? or HOW ?
methods used to achieve that aim: • measurement • analysis • modeling • prediction • control
measurement & analysis • all experiments/measurements provides data • human brain specifically designed to process images efficiently analysis usually involves graphic representation of data.
examples one quantity measured as a function of another
examples one quantity measured as a function of another
examples two quantities measured as a function of another
examples one quantity measured as a function of two others
examples one quantity measured as a function of two others
examples one quantity measured as a function of two others
examples one quantity measured as a function of three others
Examples one quantity measured as a function of three others
modeling to model and study complex problems one needs a rigorous mathematical framework
II.1.2 definitions • independent variables: control parameters, the quantities that can be varied at will. • dependent variables: the quantities that change as a consequence of the independent variable being varied.
II.2 Graphing 2 possible scales: linear and logarithmic II.2.1 the linear scale • use it when the variable has small range • the interval [a,b] has the same length as the interval [a+c,b+c]
II.2.1 the logarithmic scale • use it when the variable has large range • the interval [a,b] has the same length as the interval [a x c, b x c]
3 example types of plots • linear - linear
3 example types of plots • log - linear
