02 Metrics, Accur/Prec, Graph (McGowan)
AB
metric systemsystem international (SI)
fundemental unitsSeven basic SI units, s, A, cd, K, mol, m, kg
derived unitscombing two or more fundemental units
Scientific notation1 X 10^n
AccuracyHow close to exact value
PrecisionReproducibility
ParallaxError due to viewing at an angle.
Dependent variableresponding variable
Independent variablemanipulated variable
linear graph with intercepty = kx + b
quadratic graph (exponential)y = kx^n n > 1
inverse graph (hyperbolic)y = kx^n n < 1
linear graph without intercepty = kx (note exponent is = 1)
Reason why metric system is usedBase 10
y axisdependent axis
x axisindependent axis
