an array of simple and conditional probabilities. For example: Suppose there is a certain disease randomly found in one-half of one percent (.005) of the general population. A certain clinical blood test is 99 percent (.99) effective in detecting the presence of this disease; that is‚ it will yield an accurate positive result in 99 percent of the cases where the disease is actually present. But it also yields false-positive results in 5 percent (.05) of the cases where the disease is not present.

sample or a population is computed by adding all of the observations and dividing by the number of observations. Returning to the example of the five women‚ the mean weight would equal (100 + 100 + 130 + 140 + 150)/5 = 620/5 = 124 pounds. In the general case‚ the mean can be calculated‚ using one of the following equations: Population mean = μ = ΣX / N OR Sample mean = x = Σx / n where ΣX is the sum of all the population observations‚ N is the number of population observations‚ Σx is the sum of

ever realize it; however‚ everyone has made some form of statistical statement or thought within their everyday life; from conversations to thinking about something. Take a puppy for example. For every month in age a puppy is equates to one hour of being able to hold their bladders (Humane Society‚ 2009). Other examples would be Survey Data’s that are fundamentally amalgamated into scopes of miscalculations‚ randomized sampling as well as certainty periods. Such thoughts like these are statistical

of Hume’s (1748) An Enquiry Concerning Human Understanding. Namely‚ section six‚ Of Probability‚ and‚ section seven‚ Of the Idea of Necessary Connexion‚ focusing on the text’s key points. Hume starts section six by asserting that there is no such thing as chance in the world. Instead‚ it is our ignorance of the causes of events that lead us to believe in chance. Nevertheless‚ Hume posits that there is probability‚ that is‚ a greater chance of something taking place than a contrary. Here‚ Hume uses

Probable Probability; Rolling Dice Statistics is based upon based upon common sense and logic‚ in a complex data. Probability is just one of the many topics in statistical mathematics. It is used in our daily life‚ all over the world. Even games‚ require taking a chance and using probability to determine the predicted outcomes. Probability is the measure of how often a particular event will happen if something is done repeatedly‚ (596 Webster’s Dictionary). You cannot determine
