Summary This chapter introduces MATLAB functions that have widespread and important uses in statistics and data analysis; however, their proper application requires informed judgment and experience. Section 7.1 gives an introduction to basic statistics and...

Interpolation Engineering problems often require the analysis of data pairs. For example, the paired data might represent a cause and effect, or input-output relationship, such as the current produced in a resistor as a result of an applied voltage, or a time history,...

We often do not have a simple probability distribution to describe the distribution of outcomes in many engineering applications. For example, the probability that a circuit. consisting of many components will fail is a function of the number and the .age’of the...

The Normal Distribution Rolling a die is an example of a process whose possible outcomes are a limited set of numbers; namely, the integers from 1 to 6. For such processes the probability is a function of a discrete-valued variable, that is, a variable having a...

Statistics, Histograms, and Probability In all likelihood you have computed an average, for example, the average of all your test scores in a course. To find your average, you add your scores and divide by the number of tests. The mathematical term for this average is...
