Python Programming in Context, 3rd Edition

4.8 Summary

This chapter introduced three types of Python collections: lists, tuples, and dictionaries. Together with strings, these four data types provide us with a powerful set of tools for solving problems. To investigate the use of these collections, we developed a set of algorithms for performing basic statistical analysis. In particular, we implemented functions to compute the following:

• ▶   Dispersion (simple range and standard deviation)

• ▶   Central tendency (mean, median, and mode)

• ▶   Frequency distribution

We introduced the methods of the statistics module, which also perform these operations.Finally, we used the Turtle class to create a graphical representation of a frequency histogram.
