Standard Course Week 5 INTRODUCTION TO PROBABILITY DISTRIBUTIONS Cumulative Frequency Distributions Area under the Curve, & Probability Basics Relative frequencies Cumulative frequencies Ogives Classes in distributions Frequency distribution curves Area under the curve Fundamental concepts of probability Likelihood of events Computing probablity of sequences and combinations of independent events Basics of probability & theoretical probability distributions in Excel: Uniform Normal Chi-square F Student's-t THIS WEEK'S TEXTBOOK CHAPTER Edit Students can manually mark this item complete: THIS WEEK'S TEXTBOOK CHAPTER Statistics Text Chapter 5 -- Cumulative frequencies, areas under the curve, probability URL Edit title Edit Students can manually mark this item complete: Statistics Text Chapter 5 -- Cumulative frequencies, areas under the curve, probability Learning Objectives for This Week By the end of this week's study, students should be able to Distinguish among histogram frequencies, relative frequencies, cumulative frequencies (ascending and descending), and cumulative relative frequencies. Recognize and use the term "ogive" correctly Interpret histogram data in terms of probability of randomly selecting values less than or equal to a specific value or greater than a specific value Correctly interpret the concept of "area under the curve" in terms of actual frequencies and of probability Recognize that the maximum possible probability is 1, that the probability of an event that is certain is 1, and that the probability of an impossible value is 0. Compute the probability of the converse (P') of event P as (1 - P) Compute the probability that two or more independent events given the individual probabilities of those events Recognize when the uniform probability distribution is appropriate to use Compute probabilities based on the uniform probability distribution Recognize when the Normal (Gaussian, bell-curve) distribution is likely to be observed Describe the probabilities for various values of the standard Normal deviate z Use the appropriate Normal,t, chi-square and F distribution functions in Excel to compute probabilities of various conditions Edit Students can manually mark this item complete: Learning Objectives for This Week By the end of t...
