Chapt 8 _ Fitting data
Data from measurements
Each data point in an experiment is a set of numbers for a system
Data points represent either univariate or multivariate systems.
A univariate system has one independent variable and
Linear Regression Taylor Chapter 8
Now that we have some handle on data, and looking at error in measurement, lets look at data that should fit
a straight line.
Many experiments have parameters between two variables that is linear. In engineering for exam

SDOM As the number of measurements increases SDOM gets smaller.
Its related to the uncertainty. The uncertainty gets more precise with larger
sets of data because as the number of measurements increases, the mean is
more defined, and therefore the STD is
