planning. The decision making task of modern management is more demanding and more important than ever. Many organisations employ operations research or management science personnel or consultants to apply the principles of scientific management to problems and decision making. In this module we focus on a number of useful models and techniques that can be used in the decision making process. Two important themes run through the study guide: data analysis and decision making techniques. Firstly

The History of statistics can be said to start around 1749 although‚ over time‚ there have been changes to the interpretation of the word statistics. In early times‚ the meaning was restricted to information about states. This was later extended to include all collections of information of all types‚ and later still it was extended to include the analysis and interpretation of such data. In modern terms‚ "statistics" means both sets of collected information‚ as in national accounts and temperature

Introduction The word Probability derives from probity‚ a measure of the authority of a witness in a legal case in Europe‚ and often correlated with the witness ’s nobility. In a sense‚ this differs much from the modern meaning of probability‚ which‚ in contrast‚ is used as a measure of the weight of empirical evidence‚ and is arrived at from inductive reasoning and statistical inference. A short history of Probability Theory............ The branch of mathematics known as probability theory was inspired

Basic Probability Notes Probability— the relative frequency or likelihood that a specific event will occur. If the event is A‚ then the probability that A will occur is denoted P(A). Example: Flip a coin. What is the probability of heads? This is denoted P(heads). Properties of Probability 1. The probability of an event E always lies in the range of 0 to 1; i.e.‚ 0 ≤ P( E ) ≤ 1. Impossible event—an event that absolutely cannot occur; probability is zero. Example: Suppose you roll a normal die

Problem Set – June 11th 1. How does our spatial representation of time constitute an element of consciousness? Jaynes outlines six essential features to consciousness in modern humans. The first is spatialization. This describes the ability to metaphorically construct abstract concepts in a spatial map. For example‚ think about human history from about 1000 AD to today. How did you conceive of this concept? Did you see a timeline running left to right‚ with bullet points for the Norman Conquest
