Statistics is a study of data: describing properties of data (descriptive statistics) and drawing conclusions about a population based on information in a sample (inferential statistics). If the trial consists of ipping a coin twice, the On the other hand, emphasis is given to the notion of a random variable and, in that context, the sample space. Statistics is used to answer long-range planning questions, such as when and where to locate facilities to handle future sales. Statisticians try to interpret and communicate the results to others.

But it is hard to tell the truth without statistics." • Statistics make data into information • Develop an understanding of some basic ideas of statistical reliability, stochastic process (probability concepts). All the common summary statistics, like means and medians, variances and standard deviations, minima and maxima, percentiles, even regression lines, chi-square values, and P values, are summary statistics of distributions of data. Since Statistics involves the collection and interpretation of data, we must first know how to understand, display and summarise large amounts of quantitative information, before undertaking a more sophisticated analysis. a.

A fundamental concept in summary statistics is that of a central value for a set of observations and the extent to which the central value characterizes the whole set of data. Bhd. You should not confuse this concept with the population of a city for example. Measures of central value such as the mean or median must be coupled with measures of data dispersion (e.g., average distance from the mean) to indicate how well the central value characterizes the data as a whole. The most fundamental branch of statistics is descrip- tive statistics,that is, statistics used to summarize or describe a set of observations.
