**Tutorials on Analysis of Data using
MATLAB**

**The tutorials below are aimed at freshman engineering students using
Student Version of MATLAB, i.e. with only the symbolic toolbox. To be sure, MATLAB sells excellent toolboxes
on statistics and curve fitting, but these are not included in the Student
Version. Furthermore, while convenient,
the programs in these toolboxes are generally too “user friendly.” That is, they require little thought or
understanding.**

**The tutorials use bold italics**

**The first five tutorials use data for the
vapor pressure of carbon monoxide versus temperature as an example. These data are first fit with polynomials,
next with the Clapeyron equation, and finally with
the Antoine equation. The following
tutorials are intended to be performed in the order indicated, with each
building on the work done in the preceding.**

**3.
****Use
of MATLAB to fit data to a polynomial**

**4.
****Using theory to
correlate data**

**5.
****Using
a semi-empirical equation to correlate data**

**The next tutorial deals with descriptive
statistics for data on a single variable, including the mean, standard
deviation, histograms, cumulative distribution plots, skewness,
kurtosis and confidence limits for the mean.
It ends with a MATLAB function that calculates all of these, except a
histogram, for a given set of data.**

**6.
****Descriptive
statistics for measurements of a single variable**

**The next tutorial deals with comparison of
means of two populations using samples from those populations.**
