The interest in this paper is the use of chebyshev polynomials to approximate functions.

To use the empirical rule and chebyshev s theorem to draw conclusions about a data set. You probably have a good intuitive grasp of what the average of a data set says about that data set. Therefore 75% of the values of a data set lie within 2 standard deviations of the mean. Chebyshevtype relations, involving higher moments, which could be used to reduce this upper bound. Numerical methods and approximation theory iii mi sanu. Using the markov inequality, one can also show that for any random variable with mean and variance.

Mergelyan, uniform approximations of functions of a complex. The use of chebyshev polynomials for approximating functions. Suppose you want to find the percent of values of a data set that lie within 2 standard deviations of the mean. In this section we begin to learn what the standard deviation has to tell us about the nature of the data set. Furthermore, various classes of mathematical functions will be analyzed in order to conclude which kinds of functions could best be modeled by chebyshev polynomials. This problem is a basic example that demonstrates how and when to apply chebyshevs theorem.
