The standard normal distribution. The standard normal distribution is a . continuous distribution.. It has a mean of 0 and a standard deviation of 1. Explaining the Normal Distribution. Preliminaries: How to describe data. Discussion Question: How do we describe data in Statistics?. In this course, the way we describe data is by using the C.U.S.S. Method. We look at these characteristics:. 4-B. . Exact Area. . . . Use geometric shapes such as rectangles, . circles, trapezoids, triangles etc…. . rectangle. triangle. parallelogram. Approximate Area . . . Midpoint. Click the mouse button or press the Space Bar to display the answers.. Statistics are from ______ and parameters are from ________. In a uniform distribution everything is ______ likely.. If a distribution is skewed right, which is greater, the mean or the median and why?. History. Abraham de . Moivre. (1733) – consultant to . gamblers. . Pronunciation. .. Pierre Simon . Laplace – mathematician, astronomer, philosopher, determinist.. Carl Friedrich . Gauss – mathematician and astronomer.. Objectives:. For variables with relatively normal distributions:. Students should know the approximate percent of observations in a set of data that will fall between the mean and ± 1 . sd. , 2 . sd. Review Bell Ringer. Section 3.1. Section 3.2. Figure 3.1 is a histogram of the scores of all 947 seventh-grade students in Gary, Indiana, on the vocabulary part of the Iowa Tests of Basic Skills.1 Scores of many students on this national test have a quite regular distribution. The histogram is symmetric, and both tails fall off smoothly from a single center peak. There are no large gaps or obvious outliers. The smooth curve drawn through the tops of the histogram bars in Figure 3.1 is a good description of the overall pattern of the data..  . Want more tools and templates? .
