Statistics
Statistics prepares students for our changing technological world. So-called "big data" and A.I. technology are built upon statistical foundations, and statistical thinking is becoming increasingly important in the job market. In this course students learn inferential and descriptive statistics, become comfortable with experimental methods as well as data sets, both in their raw and graphical forms. Students learn to interpret histograms, stem plots, time plots, and scatter plots. They use descriptive statistics such as the median, mean, and standard deviation to describe data, and evaluate data distributions. Students examine relationships using correlations and least square regressions, and calculate the probability of simple and compound events. They estimate confidence intervals and explore tests of significance, as well as evaluate the statistical validity.
