Recall that the probability of an event occurring given that another event has already occurred is called a conditional probability. The probability that event B occurs, given that event A has already occurred is This formula comes from the general multiplication principle and a little bit of algebra. Since we are given that event A has occurred, we have a reduced sample space. Instead of the entire sample space S, we now have a sample space of A since we know A has occurred. So the old rule about being the number in the event divided by the number in the sample space still applies. After that last part, you have just worked a Bayes' Theorem problem. It is the number in A and B (must be in A since A has occurred) divided by the number in A. I know you didn't realize it - that's the beauty of it. If you then divided numerator and denominator of the right hand side by the number in the sample space S, then you have the probability of A and B divided by the probability of A. A Bayes' problem can be set up so it appears to be just another conditional probability. In this class we will treat Bayes' problems as another conditional probability and not involve the large messy formula given in the text (and every other text).
This unit on probability covers how to use simulations to calculate experimental probabilities and a variety of other methods the addition rule, the multiplication rule, conditional probability for calculating probability. Later, we'll use our understanding of probability to answer statistical questions. Probability forms the backbone of many important data science concepts from inferential statistics to Bayesian networks.

Statistics and Probability. This website provides training and tools to help you solve statistics problems quickly, easily, and accurately - without having to ask anyone for help. Probability and statistics, the branches of mathematics concerned with the laws governing random events, including the collection, analysis, interpretation, and display of numerical data. Probability has its origin in the study of gambling and insurance in the 17th century, and it is now an indispensable tool of both social and natural sciences. Statistics may be said to have its origin in census counts taken thousands of years ago; as a distinct scientific discipline, however, it was developed in the early 19th century as the study of populations, economies, and moral actions and later in that century as the mathematical tool for analyzing such numbers. For technical information on these subjects, Probability is a subject that deals with uncertainty. In everyday terminology, probability can be thought of as a numerical measure of the likelihood that a particular event will occur. Fermat and Pascal proposed somewhat different solutions, though they agreed about the numerical answer. Probability values are assigned on a scale from 0 to 1, with values near 0… Each undertook to define a set of equal or symmetrical cases, then to answer the problem by comparing the number for . Fermat, however, gave his answer in terms of the chances, or probabilities. He reasoned that two more games would suffice in any case to determine a victory.

Asking these kind of questions will only help you to understand what subjects think who they want to be, not their actaul selves. Considering that you are interested in health-related variables that are the variables affecting your health in a way, I'd go for data that is collected from the subject via a reliable. Decisions or predictions are often based on data—numbers in context. These decisions or predictions would be easy if the data always sent a clear message, but the message is often obscured by variability. Statistics provides tools for describing variability in data and for making informed decisions that take it into account. Data are gathered, displayed, summarized, examined, and interpreted to discover patterns and deviations from patterns. Quantitative data can be described in terms of key characteristics: measures of shape, center, and spread. The shape of a data distribution might be described as symmetric, skewed, flat, or bell shaped, and it might be summarized by a statistic measuring center (such as mean or median) and a statistic measuring spread (such as standard deviation or interquartile range). Different distributions can be compared numerically using these statistics or compared visually using plots. Knowledge of center and spread are not enough to describe a distribution.

Measure the foot size, the leg length, and you can deduce the footprints. Bubbles weighs 400lbs and has 3-foot legs, and will make tracks like this." More academically: "We have a fair coin. After 10 flips, here are the possible outcomes." Statistics is harder. If we get 6 heads and 4 tails, what're the chances of a fair coin? We measure the footprints and have to guess what animal it could be. Here's how we "find the animal" with statistics: Get the tracks. Each piece of data is a point in "connect the dots". Once we have the distribution ("bears"), we look up our generic measurements in a table. " questions: These questions are much deeper than what I pondered when first learning stats. The forwards-backwards difference between probability and statistics shows up all over math. The more data, the clearer the shape (1 spot in connect-the-dots isn't helpful. "A 6-inch wide, 2-inch deep pawprint is most likely a 3-year-old, 400-lbs bear". Once we know the animal, we can predict future behavior and other traits ("According to our calculations, Mr. Statistics helps us get information about the origin of the data, from the data itself. The metaphor isn't perfect, but more palatable than "Statistics is the study of the collection, organization, analysis, and interpretation of data". Every dry procedure now has a context: are we learning a new species? How to make a table from a probability distribution? Having an analogy for the statistics process makes later data crunching click. Some procedures are easy to do (derivatives) but difficult to undo (integrals). One data point makes it hard to find a trend.) Measure the basic characteristics. Every data set has a mean, median, standard deviation, and so on. The lookup table is generated from the probability distribution, i.e. These universal, generic descriptions give a narrowing: "The footprint is 6 inches wide: a small bear, or a large man? There are dozens of possible animals (probability distributions) to consider. We narrow it down with prior knowledge of the system.

Middle school math instruction includes the beginnings of probability and statistics, where students become acquainted with math applied to real problems. Probability and statistics is not purely mathematics, as it includes the sciences and is expressed in a language of its own. As math teachers present sets of data, review how they were sampled, examine their distributions, explain basic mathematical manipulations to identify trends, and draw inferences from the data, students are immersed in statistical terminology.

The probability of an event occurring is the chance or likelihood of it occurring. The probability of an event A, written P(A), can be between zero and one, with P(A) = 1 indicating that the event will certainly happen and with P(A) = 0 indicating that event A will certainly not happen. Probability can be studied in conjunction with set theory, with Venn Diagrams being particularly useful in analysis. The probability of a certain event occurring, for example, can be represented by P(A). The probability of a different event occurring can be written P(B). Clearly, therefore, for two events A and B, P(AÇB) represents the probability of A AND B occurring. P(AÈB) represents the probability of A OR B occurring. The rectangle represents the sample space, which is all of the possible outcomes of the experiment. In other words, all of the points within A represent possible ways of achieving the outcome of A. So in the diagram, P(A) P(B) is the whole of A (the whole circle) the whole of B (so we have counted the middle bit twice). A" is the complement of A and means everything not in A. Note that the probability that A occurs the probability that A does not occur = 1 (one or the other must happen). Thus: Events A and B are mutually exclusive if they have no events in common.

Data Analysis, Statistics, and Probability are mathematical processes that help solve real-world problems. Probability helps predict the likelihood that an event will happen. To help predict the likelihood of events, people use statistical information and data. In mathematics, the probability is a branch that studies the results or consequences of mathematical data. On the other hand, Statistics is a branch of mathematics that helps you make sense of data.

In the worm plot depicted, England’s performance is described by the blue line, and the West Indies’ by the green line. You can see at a glance that, although there was variation in the run rate, England consistently scored at a higher rate than the West Indies, and so won the match. Although some information has been lost - you don't know for instance from which balls in the overs runs were taken - this summary graph clearly displays all of the meaningful information. The human mind is very visual, and this is why graphics, such as graphs or pie charts, are very good for conveying statistical information. This used to obtain information about a large set of data from a smaller sample. Here, the statistician randomly selects a group of people, a thousand say, and asks them about their opinion, for example whether or not they like the current government.
