Descriptive Statistics (graded) If you were given a large data set such as the sales over the last year of our top 1,000 customers, what might you be able to do with this data? What might be the benefits of describing the data? Week 2 Regression (graded) Suppose you are given data from a survey showing...

B. Weaver (31-Oct-2005) Probability & Hypothesis Testing 1 Probability and Hypothesis Testing 1.1 PROBABILITY AND INFERENCE The area of descriptive statistics is concerned with meaningful and efficient ways of presenting data. When it comes to inferential statistics, though, our goal is to make...
sunny or cloudy. If a day is sunny, the following day will be sunny with probability 0.60. If a day is cloudy, the following day will be cloudy with probability 0.70. Suppose it is cloudy on Monday. a) What is the probability that it will be sunny on Wednesday? There are two mutually exclusive ways...
series, such series is termed as normal frequency distribution or just frequency distribution. On the contrary, when there is estimation as to how the outcomes for any event will vary, they form a theoretical frequency distribution. FREQUENCY DISTRIBUTION • Observed frequency • Event occurred ...
