Outline of Chapter 6 text - Elementary Statistics: A Brief Version(A. Bluman 3rd Ed., 2003)

Chapter 6 Outline Identify disseminations as symmetrical or skewed. Identify the properties of the pattern statistical dispersion. Find the range under the prototype natural distribution, given various z values. Find the probabilities for a normally distributed variable by transforming it into a standard normal variable. Find specific entropy values for given percentages physical exercise the standard normal distribution. Use the central limit theorem to reckon problems involving standard baseborns for large samples. Use the normal approximation to count on probabilities for a binomial variable. Introduction Many continuous variables swallow distributions that be price-shaped and are called approximately normally distributed variables. A normal distribution is also cognize as the bell curve or the Gaussian distribution. principle and skew Distributions The normal distribution is a continuous, bell-shaped distribution of a variable. If the data values are evenly distributed about the designatespirited, the distribution is utter to be symmetrical. If the majority of the data values illume to the fishy or castigatefulness of the mean, the distribution is said to be skewed. Left skewed Distributions When the majority of the data values fall to the unspoiled of the mean, the distribution is said to be negatively or odd skewed. The mean is to the odd of the median, and the mean and the median are to the left(p) of the mode.

duty Skewed Distributions When the majority of the data values fall to the left of the mean, the distribution is said to be positively or right skewed. The mean falls to the right of the median and both the mean and th e median fall to the right of the mode. Equa! tion for a radiation diagram Distribution The numeric equation for the normal distribution is: Properties of the Normal Distribution The shape and government agency of the normal distribution curve depend on deuce parameters, the mean and the...
