Topics for descriptive statistics include graphical displays, measures of center, measures of variation, and measures of position. You can learn how to create histograms, Ogives and other displays. Learn how to calculate the mean, median, and mode. Find variance and standard deviation. Find the 5 number summary, and use them to create box plots (box and whisker plots). This section focuses on how to describe the data that you have found.
Topics on this page include how to create a scatter plot, how to find the correlation coefficient, and how to create regression equation. This is a new page, and more content will be added in the near future.
Topics include different types of probability. Setting up probability distributions for discrete random variables. Finding probabilities of discrete and continuous random variables. Using graphing calculators to help find probabilities of various probability distributions. Find expected values of a probability distribution. Find the mean, variance and standard deviation of probability distributions. Explore various types of probability distributions. The central limit theorem and applications.
Topics include the explanation of confidence intervals, how to create z-intervals, t-intervals, and 1-proportion z-intervals. All intervals will be created using the formula for the designated confidence interval, as well as how to verify your intervals in the TI-84 and TI-Nspire graphing calculator.
Topics include how to perform and identify when to use specific types of hypothesis testing. The types include a z-test for the mean, a t-test for the mean, and a 1-proportion z-test. All hypothesis tests will be modeled by hand and with the TI-84 and TI-Nspire graphing calculators. Both p-value and rejection region decision rules will be utilized. More hypothesis tests will be added in the future.
